California Highways (www.cahighways.org): Route 49

(3) From Route 120 near Chinese Camp to Route 80 near Auburn via the vicinity of Sonora; via Angels Camp, San Andreas, and Jackson; and via the vicinity of El Dorado, Diamond Springs, and Placerville.

(b) The relinquished former portion of Route 49 within the City of Auburn is not a state highway and is not eligible for adoption under Section 81. For the relinquished former portion of Route 49, the City of Auburn shall maintain within its jurisdiction signs directing motorists to the continuation of Route 49. The city may apply to the department for approval of a business route designation in accordance with Chapter 20, Topic 21, of the Highway Design Manual.

Post 1964 Signage History

As defined in 1963, this was a single segment running from "Route 120 to Route 20 via Sonora, Angels Camp, San Andreas, Jackson, El Dorado, Diamond Springs, Placerville, and Auburn." Before the year was out, this was split into two segments by Chapter 1698: "(b) Route 120 to Route 80 in Auburn via the vicinity of Sonora; via Angels Camp, San Andreas, and Jackson; via the vicinity of El Dorado, Diamond Springs, and Placerville. (c) Route 80 near Auburn to Route 20."

In 1965, Chapter 1372 changed the wording further to "Route 120 near Chinese Camp to Route 80 in Auburn via the vicinity of Sonora; via Angels Camp, San Andreas, and Jackson; via the vicinity of El Dorado, Diamond Springs, and Placerville." This change has the side effect of transferring the former segment of cosigned Route 108/Route 49 between Yosemite Junction NE to Route 49 formally to Route 108, and to eliminate the cosigning of Route 120 with Route 49 from Route 49 near Chinese Camp NW to Yosemite Junction.

In 1968, Chapter 282 changed the terminus to "Route 80 near Auburn".

According to Joe Rouse, the segment of Route 49 from Moccasin to Chinese Camp was supposed to be part of a four-lane freeway/expressway facility on Route 120 from Oakdale to (he thinks) somewhere near Groveland. This would have included a replacement of New Priest Grade. Because it's built to two-lane expressway standards, the speed limit is higher. The James Robert Bridge across Lake Don Pedro was built to accommodate four lanes; as a result, the piers are wider than the structure itself with Y-shaped bent caps that now only support one set of lanes.

Sonora Bypass Proposal In 1968, the CHC began discussing proposals for the Sonora Bypass. The 6.1 mi section, a combination of Route 49 and Route 108, extends from 0.4 mi W of Mooney Road S of Jamestown to 1.1 mi E of Sonora. The recommended alternative was designated as A-2. It leaves the alignment of existing Route 49 0.5 N of Mooney Road to run due N for about a mile. It then turns NE, recrossing the existing highway N of Jamestown and continuing to near the SW corner of Sonora. It then jogs E to pass 0.5 mi S of Sonora before turning generally NE again to join a previously adopted freeway at existing Route 108 immediately E of Pine Road. The plan is for a scenic expressway, not a freeway, at this point. Route A-1, the other proposal, was identical to A-2 from the western start for more than half the total route distance, splitting a half-mile east of Volponi Acres at Mill Villa Hill, where A-2 heads S to join up with Route B, near Campo Seco Road. Route A-1 at Mill Villa Hill jogs S of the existing highway and passes through the southern edge of Sonora, crossing Washington and Stewart Sts. on a 40' high overpass. Route B immediately heads S after crossing the Jacksonville Road generally paralleling Campo Seco Road.

In 2008, Chapter 635 (AB 1915, 9/30/2008) authorized the relinquishment of the portion within the city limits of the city of Auburn, with the usual terms and conditions language:

(1) The commission may relinquish to the City of Auburn the portion of Route 49 that is located within the city limits of that city, upon terms and conditions the commission finds to be in the best interests of the state, if the department and the city enter into an agreement providing for that relinquishment.

(2) A relinquishment under this subdivision shall become effective immediately following the county recorder's recordation of the relinquishment resolution containing the commission's approval of the terms and conditions of the relinquishment.

(3) On and after the effective date of the relinquishment, the relinquished portion of Route 49 shall cease to be a state highway.

(4) The portion of Route 49 relinquished under this subdivision shall be ineligible for future adoption under Section 81.

(5) For the portion of Route 49 that is relinquished under this subdivision, the City of Auburn shall maintain within its jurisdiction, signs directing motorists to the continuation of Route 49. The city may apply to the department for approval of a business route designation in accordance with Chapter 20, Topic 21, of the Highway Design Manual.

The portion within Auburn was relinquished in May 2009.

In September 2012, AB 2679, Chapter 769, updated the text to recognize that the portion had been relinquished.

SB 788 (Chapter 525, 10/9/2013) Delted the relinquishment wording to eliminate the requirement for continuity of traffic flow:

(b) The relinquished former portion of Route 49 within the City of Auburn is not a state highway and is not eligible for adoption under Section 81. For the relinquished former portion of Route 49, the City of Auburn shall maintain within its jurisdiction signs directing motorists to the continuation of Route 49 ~~and shall ensure the continuity of traffic flow on the relinquished portion of Route 49, including any traffic signal progression~~. The city may apply to the department for approval of a business route designation in accordance with Chapter 20, Topic 21, of the Highway Design Manual.

Pre 1964 Signage History

In 1934, Route 49 was signed along the route from Jct Route 140 at Mariposa to Jct. Route 24 (now Route 70) near Reno Jct, via Sonora, Jackson, and Nevada City. Between Chinese Camp and Sonora, a different route is used. Picture a triangle:

One leg is the new route from Route 49/Route 120 to Route 49/Route 108 near Sonora. This is signed Route 49.
Another leg is former LRN 13, and runs from Route 108/Route 120 near 4 mi NW of Chinese Camp to Route 108/Route 49 near Sonora. This is signed Route 108.
The third leg (LRN 40) runs from Route 120/Route 49 near Chinese Camp to Route 120/Route 108 4 mi NW of Chinese Camp). This is signed Route 120.

Between Route 120 and Route 108 S of Jamestown, this was a new routing for Route 49 defined in 1965. Between Route 108 S of Jamestown and Route 108 near Sonora, this was LRN 13 (1910). Between Route 108 near Sonora and US 50, Route 49 was LRN 65, defined in 1933. The segment between US 50 and I-80 was defined in 1921.

Jacksonville (Former Route 49: ~ Route 120 TUO R19.352)

Jacksonville was a California Gold Rush mining community located on the Tuolumne River of southwest Tuolumne County. The original alignments of Sign Route 49 and Sign Route 120 both once passed through the town site of Jacksonville. Jacksonville was razed during 1967-71 to make way for the expanded Don Pedro Lake which inundated the town site.
(Source: Gribblenation Blog (Tom Fearer), "Former California State Route 49 and California State Route 120 through Jacksonville", 7/13/2023)

In 1853 the Grizzly Gulch Trail was declared a public highway by Tuolumne County. By 1859, a new highway was completed along the southern flank of Grizzly Gulch as a franchise toll road. This highway at the time was known as the Grizzly Gulch Wagon Road and provided direct access from Jacksonville to the Big Oak Flat-Groveland area. This was later renamed Priest Grade Road. In 1912, the communities of Big Oak Flat and Groveland hired a surveyor to locate a new grade along the northern flank of Grizzly Gulch as replacement for the Priest Grade. Construction of a seven-foot-wide roadway along northern Grizzly Gulch began in 1912 via local donations. By 1913, the New Priest Grade Road was completed. New Priest Grade Road was also purchased by Tuolumne County as a public roadway. The State of California added the New Priest Grade Road as part of LRN 40 via legislation in 1915 as:
(Source: Gribblenation Blog (Tom Fearer), "Former California State Route 49 and California State Route 120 through Jacksonville", 7/13/2023)

"that certain toll road in Tuolumne and Mariposa counties known as the Big Oak Flat and Yosemite Toll Road beginning at a point near the former location of Jack Bell Sawmill in Tuolumne Cty and extending thence in an E-ly direction through a portion of Mariposa Cty at Hamilton Station, thence again into Tuolumne Cty, past Hearden Ranch, Crocker Station, Crane Flat, and Gin Flat to the boundary line of the original Yosemite Grant near Cascade Creek."

The road was modernized to state highway standards in 1927. During 1933, LRN 65 was extended south of Sonora to Mariposa by way of Chinese Camp and Jacksonville. This served to connect the traditional communities of the California Gold Rush via the so called "Mother Lode Highway." In 1934, when Sign Routes were announced, Jacksonville became host to a multiplex: Sign Route 49 and Sign Route 120 along the Tuolumne River. Sign Route 49 was aligned from Sign Route 140 in Mariposa to Sign Route 24 at Reno Junction. Sign Route 120 was aligned from US 99 in Manteca to Sign Route 168 near Benton. Sign Route 120 east of Jacksonville followed New Priest Grade Road, Big Oak Flat Road and Tioga Pass Road through Yosemite National Park over the Sierra Nevada Mountains. In 1962, public hearings were held to discuss the relocation of Sign Route 120/LRN 40 from Yosemite Junction to Groveland due to the proposed expansion of the Don Pedro Reservoir. The realignment would also include portions of Sign Route 49 through the Chinese Camp and Jacksonville area. The adoption of a new alignment occurred in 1963. Construction on the expansion of Don Pedro Dam began in August 1967 and was formally dedicated upon completion during May 1971. Route 120 and Route 49 were realigned in the Chinese Camp-Moccasin corridor to a new two-lane expressway. The town site of Jacksonville was submerged under the waters of Don Pedro Lake. The realignment of Route 49 and Route 120 shifted both highways to the south bank of the Tuolumne River and Don Pedro Lake.

Jamestown (~ TUO 13.477 to ~ TUO 16.516)

The First State Highway Bond Act defined the road from Salida east to Sonora through Jamestown as a State Highway; this eventually became LRN 13. The routing of LRN 13 through Jamestown was via Main Street. In 1934, this was signed as part of Sign Route 49. In 1941, Sign Route 49/LRN 13 south of Jamestown was relocated off of what is now Harvard Mine Road; the new alignment was dedicated on August 31, 1941. The September/October 1948 California Highways & Public Works notes that Sign Route 108 was extended west of Jamestown co-signed with Sign Route 49, to at least Montezuma Road. The bypass of Jamestown alignment of Route 49/Route 108 opened sometime between 1967 and 1970.

Jackson (~ AMA 2.252 to ~ AMA 5.453)

LRN 34 was defined in 1909 as "From LRN 4 near Arno to Jackson". LRN 34 was extended over Carson Pass to Hope Valley by way of legislative action taken during 1911. Prior to 1933 the State of California was prohibited from maintaining highways within incorporated cities. The through route in Jackson for eastbound LRN 34 appears to have always entered Jackson via Sutter Street which passed by the active mines in the city. The through route through Jackson for LRN 34 eastbound towards Carson Pass would have been via Main Street, Water Street and Broadway. Then, in 1921, LRN 65 was defined, providing a north/south state highway through Jackson. LRN 65 was defined as "...that portion of the public highway commencing at Auburn in Placer County through Placerville, Jackson, San Andreas, and Angels to and connecting with the state highway at Sonora, Tuolumne county..." LRN 65 passed through the city of Jackson northbound via Broadway, Water Street, Main Street and Sutter Street towards Martell. In 1933, the state codes were changed permitting state highways within cities; and in 1934, the sign route system was created. The entirety of LRN 65 was assigned as a portion of Sign Route 49. Sign Route 8 was assigned as a new highway that followed LRN 5 from Stockton to Mokelumne Hill, LRN 65 to Jackson and LRN 34 over Carson Pass. Sign Route 49 and Sign Route 8 both multiplexed north from Mokelumne Hill into Jackson via Broadway. At Water Street, Sign Route 8 split east via LRN 34 towards Carson Pass whereas Sign Route 49 followed LRN 65 through downtown Jackson via Main Street and Sutter Street towards Martell. By 1940, Sign Route 8 had been truncated to Mokelumne Hill in favor Sign Route 88 east of Jackson. Sign Route 88 eastbound had entered Jackson multiplexed with Sign Route 49 southbound on Sutter Street, Main Street and Water Street towards Broadway. Sign Route 88 originated from Stockton and reached Jackson via LRN 97 (added to the State Highway System during 1935) and LRN 34.
(Source: Gribblenation Blog (Tom Fearer), "The history of California State Route 49, 8 and 88 in Jackson", 4/10/2023)

In 1944, a realignment of Sign Route 49, Sign Route 88, LRN 34 and LRN 65 in Jackson was approved by the California Highway Commission as a Post-World War II project. Sign Route 49 and LRN 65/Mother Lode Highway were realigned west of downtown Jackson onto a new bypass alignment. Sign Route 88 followed the new western bypass of downtown to a new junction at the Carson Pass Highway/LRN 34 south of Jackson Creek. The new highway alignments in Jackson were dedicated on August 7, 1948, by State Highway Commissioner Homer P. Brown and Jackson Mayor Edward T. Wise. The alignment of Sign Route 49 and Sign Route 88 in Jackson have remained unaltered since August 1948.

San Andreas (~ CAL 19.414 to CAL R22.241)

Modern Route 49 currently passes through San Andreas via a bypass of downtown on St. Charles Street. Prior to the current bypass alignment being constructed, Route 49 passed through San Andreas via Main Street and Gold Strike Road. The state highway system came to San Andreas with the 1909 First State Highway Bond Act, which defined what would become LRN 24. The original definition of LRN 24 had San Andreas as the eastern route terminus with the highway originating at LRN 4 in Lodi. An eastern segment of LRN 24 was added to by 1911 Legislative Chapter 468, which annexed the Big Trees Toll Road over Ebbetts Pass into the State Highway System. A second highway in San Andreas was added to the State Highway System as part of 1921 Legislative Chapter 839, which defined what would become LRN 65. LRN 65 passed north/south through San Andreas and originally was defined as: "All that portion of the public highway commencing at Auburn in Placer County through Placerville, Jackson, San Andreas and Angels to and connecting with the state highway lateral at Sonoma, Tuolumne county is hereby... declared to be a state highway... highway shall be known as the "Mother Lode Highway"." 1934 saw the signage of routes, and Route 12 and Route 49 were added as Sign Routes directly serving San Andreas. Route 12 terminated in San Andreas via the western segment of LRN 24 at Route 49/LRN 65, at the intersection of St. Charles Street at Main Street. Route 49 followed LRN 65 through San Andreas via southern St. Charles Street, Main Street and Gold Strike Road. By 1963, a new bypass alignment of Route 49/LRN 65 was in the process of construction, as Main Street in downtown San Andreas was an choke point on Route 49/LRN 65.

Placerville (~ ED 14.043 to ED 16.255)

Rte 49 Proposed Placerville Adoption In a discussion on AARoads, Nathan Edgars (NE2), Scott Parker (Sparker) and Tom Feaerer (Max Rockatansky) provide more history: Route 49 through Placerville is surprisingly steep and narrow for a route that runs to a downtown area. With all the work it must have taken to get an expressway on US 50 it seemed like it would be an obvious choice to upgrade. It appears that the alignment of Route 49 in Placeville is original as most of the infrastructure would have existed back in 1934. US 50 would have run on Main Street originally which had a brief multiplex with Route 49. The four lane expressway US 50 now takes through Placerville appears to have been complete by 1957 or 1958.
(Source: AARoads Discussion, June 2017)

In 1962, public hearings were held for the future relocation of about 23 miles of Route 49 in El Dorado County from the Amador County Line to Coloma. The relocation map shows a number of feasible options under consideration. These options connected on the S to the existing state highway, and on the N to a segment of Route 49 adopted 3/16/1959. The route also connected to the new routing of US 50, adopted 4/25/1962.

Rte 49 Placerville Recission In 1982, notice was published regarding rescinding of the route adoption of a 7.7 mi segment of Route 49 N of US 50 between US 50 and Marshall Road. This segment was adopted in 1964. It connected with a separate segment S of US 50 that was rescinded by the CHC back in 1975. The ostensible reason for the rescission was lack of funds. The two segments together would have created a future bypass of the downtown Placerville area. This may be the route shown as A on the proposal map.

Rte 49 Lotus to Cool Realignment In 1958, public meetings were held on the proposed realignment of Route 49 between Lotus and Cool. The proposal calls for the eventual realignment of 10.3 mi of Route 49, beginning at Cool and generally following the present highway to a point near Pilot Hill, where it crosses the existing road and continues in an E direction N of the present alignment to about 1 mi W of Hastings Creek. From this point to Hastings Creek, the existing alignment will generally be utilized. At Hastings Creek, the road will be on a new alignment south of the present road to just E of Greenwood Creek. Between Greenwood Creek and Brush Creek, the route again follows the existing alignment. At Brush Creek, the highway again departs the existing alignment and continues E on a new alignment S of the present road to Lotus Road where it will join the portion of Route 49 that was relocated after the heavy storms of 1955.

In a discussion on AARoads, Nathan Edgars (NE2), Scott Parker (Sparker) and Tom Feaerer (Max R) provide more history: The Foresthill Bridge (near ~ ED 38.233, which is accessible for free so long as you tell the people at the ranger station all you want is a picture or two) was constructed from 1971 to 1973 and was intended to be a realignment of Route 49 for the Auburn Dam Project. The Auburn Dam Project was stopped in 1975 after an earthquake due to the design of the dam being deemed insufficient to withstand a similar magnitude with the concrete gravity arch design. The Auburn Dam was supposed to the tallest dam in the United States and would have flooded the confluence of the North Fork and Middle Fork American River where Route 49 traverses. The original alignments of Route 49 through Grass Valley and Nevada City would have probably been: Auburn Street, Main Street, Nevada City Highway, Sacramento Street, and Broad Street. With Grass Valley, Route 20 would have come in to meet Route 49 via the Rough and Ready Highway at the intersection of Main Street and Auburn Street. Route 20 would have multiplexed Route 49 all the way to Nevada City where it continued over Sacramento Street onto Nevada Street. LRN 25 would have met Route 20 and Route 49 in Grass Valley at Bennett Street, which would have become Route 174 during the 1964 renumbering. The modern freeway alignment of Route 20/Route 49 can be seen in development from 1966 to 1969 State Highway Maps. Route 20 seems to have been realigned off the Rough and Ready Highway to the south to meet Route 49 at Empire Street sometime between 1982 and 1986.

In March 2012, the CTC authorized vacation of right of way in the county of Tuolumne near Sonora along Route 49 at Poppy Hills Drive (~ TUO 23.402), consisting of highway right of way no longer needed for State highway purposes. The County of Tuolumne was given a 90-day notice of intent to vacate, without protesting such action.

In May 2019, the CTC approved for future consideration of funding a project is located on Route 49 near the town of Tuttletown in Tuolumne County (10-Tuo-49, PM 25.3). The project proposes to widen the southbound side of Route 49 at post mile 25.3. The proposed project addresses the need to provide adequate pavement width to accommodate Surface Transportation Assistance Act design vehicles. The project will also address the need to reduce recurring maintenance repair work on shoulder damage caused by trucks driving off the route pavement edges. The estimated total cost of the proposed project is $2.6 million and is not currently programmed. Construction is estimated to begin in 2021.

Construction is estimated to begin 2026-27. The scope, as described for the preferred alternative, is consistent with the project scope as programmed by the Commission in the 2022 SHOPP. A copy of the MND has been provided to Commission staff. The project will result in less than significant impacts to the environment after mitigation. The following resource areas may be impacted by the project: visual aesthetics due to the loss of heritage oak trees. Avoidance, minimization, and mitigation measures will reduce any potential effects to the environment. These measures include, but are not limited to, paying in-lieu fees to the City of Angels Camp Oak Tree Preservation Fund, per the City of Angels Camp Oak Tree and Heritage Tree Ordinance. As a result, a MND was completed for this project.

In September 2021, Caltrans started holding open houses regarding a project to improve the intersection of Route 26 and Route 49 (~10-Cal-49 PM 27.565/27.66; 10-Cal-26 18.022/CAL 18.118), as a result of a number of broadside collisions. The intersection where the two highways meet currently has a four-way stop, which Caltrans believes warrants an overhaul. Proposed alternatives to the current four-way stop include a roundabout (Alternative 1) or two-signal stop lights (Alternative 2), with the third option being to leave it as-is (Alternative 3). According to Caltrans, a pattern of broadside collisions has been identified at the intersection of Route 26 and Route 49, which are caused by motorists failing to yield. The proposed roundabout is estimated to cost close to $10.5 million dollars, while the traffic signal would cost about half of that, at $4.8 million. Pros for the roundabout listed online by Caltrans include eliminating head-on and broadside collisions, more continuous flow of traffic, less noise and air pollution, and they are more pedestrian-friendly. An obvious con is the cost, as well as more difficult construction staging. Pros listed for a traffic signal include easier construction staging, more cost-effectiveness, and ease of use as drivers are already familiar with traffic signals at intersections. A major con listed is higher through-speeds and more “conflict points” leading to more severe collisions. Other cons listed are less continuous flow of traffic, less pedestrian-friendly, and less access to businesses near the intersection. In a Facebook poll posted in a Mokelumne Hill community group, the majority of votes were for leaving the intersection as-is, at 103 votes. The next highest response, at 32 votes, was in favor of a roundabout, and only six votes went to the signal option. Several community members submitted their own suggestions, including decreasing the speed limits through the intersection, adding rumble strips, flashing lights, or making stops required one way, with cross-traffic required to yield. Two votes went to the proposal to “pay attention and drive.” A tentative schedule provided by Caltrans estimates project completion by November of 2025.

In October 2022, the CTC approved for future consideration of funding Highway 26/49 Intersection Control Improvement Project (10-Cal-26, PM 18.10, 10-Cal-49, PM 18.10). Improve safety at the intersection of Route 26 and Route 49, in Mokelumne Hill, in Calaveras County. The project is located at the intersection of Route 26 and Route 49, in Calaveras County. The Department proposes to construct a roundabout at the intersection of Route 26 and Route 49 in the town of Mokelumne Hill to reduce the number and severity of broadside collisions at the intersection. This project is fully funded and currently programmed in the 2022 SHOPP for a project total of $18,952,000, which includes Right of Way (capital and support) and Construction (capital and support). Construction is estimated to begin in 2024-25. The scope, as described for the preferred alternative, is consistent with the project scope as programmed by the Commission in the 2022 SHOPP.

In November 2005, the CTC considered relinquishment of right of way in the City of Sutter Creek, at the entrance to the Sutter Terrace Mobile Home Park (~ AMA 4.542), consisting of reconstructed and relocated city streets.

Amador/Sutter Creek Bypass

The Amador/Sutter Creek bypass of Route 49 is planned to follow a new, straighter alignment from the Route 104/49 junction in Sutter Hill (~ AMA 6.95) north to Drytown (~ AMA 13.485).

Between 2002 and 2006, a bypass was constructed of the cities of Sutter Creek and Amador City (~ AMA R7.306 to AMA R10.762). The EIR came back with a negative declaration in May 2002 (CTC May 2002 2.2c.(1)). The bypass was a two-lane expressway that opened in mid-November 2006.

In March 2006, the CTC considered relinquishment of right of way in the city of Amador City, consisting of superseded highway right of way. The City of Amador City, by relinquishment agreement dated March 20, 2003, and by amendment to agreement dated December 29, 2006, waived the 90-day notice requirement and agreed to accept title upon relinquishment by the State. The CTC also considered relinquishment of right of way in the city of Sutter Creek, consisting of superseded highway right of way and reconstructed city street. The City of Sutter Creek, by controlled access highway agreement dated March 17, 2003, agreed to accept title upon relinquishment by the State. The City by relinquishment agreement dated March 17, 2003, and by amendment to agreement dated December 29, 2006, waived the 90-day notice requirement and agreed to accept title upon relinquishment by the State.

In December 2007, five segments of right of way in the county of Amador, between PM 9.0 and 11.7, consisting of superseded highway right of way and relocated and reconstructed county roads, were up for relinquishment.

In August 2014, the CTC authorized vacation of right of way in the county of Amador along Route 49 near its junction with Main Street (this is N of Sutter Creek but S of Amador City), consisting of superseded highway right of way no longer needed for State highway purposes. The County was given a 90-day notice of intent to vacate and did not protest such action (10-Ama-49-PM R10.8).

Plymouth: Shenandoah Road Interchange (~ AMA 17.226)

The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, provided the following expenditures on or near this route:

High Priority Project #3321: Improvement of Main Street - Shenandoah Road/Route 49 Intersection, Plymouth. $800,000.

In July 2017, it was reported that Caltrans is partnering with Plymouth and the Amador County Transportation Commission to convert an intersection with four stop signs into a user-friendly roundabout. The project broke ground Friday, July 14, at the site where Route 49 connects with Shenandoah Road and Main Street. The Route 49 Plymouth Roundabout is expected to have a total project cost of $6 million and be finished in the spring of 2018. George Reed Construction of Modesto is performing the work. Rather than all four vehicles being forced to come to a complete stop, idling their engines and contributing to noise and air pollution, motorists will glide through the roundabout with minimal delay. It will also benefit farm equipment turning east onto Shenandoah Road, and commercial trucks turning west onto Main Street or passing through on the way to Jackson or Placerville. This Route 49 intersection also will be upgraded to the standards of the Surface Transportation Assistance Act, providing easier access for large trucks and tractors bringing in supplies and hauling out wine grapes, produce and livestock.

Curve near Nashville In March 2012, the CTC approved for future consideration of funding a project that will improve safety by replacing a compound curve with a single radius curve, widening the lanes and shoulders, and removing trees to improve sight distance along Route 49 (~ ED 3.868). The project is programmed in the 2010 State Highway Operation and Protection Program (SHOPP). The total estimated project cost is $2,601,000 for capital and support. Construction is estimated to begin in Fiscal Year 2012-13. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2010 SHOPP.

[Route 49 near El Dorado] In February 2009, the CTC approved a project to realign, widen and add shoulders on Route 49 near El Dorado (03-ED-49, PM 6.6/8.2). Depending on the availability of funding, it is estimated that the Department will begin construction in Fiscal Year 2008-09.

Patterson Signalization In April 2012, the CTC approved for future consideration of funding a project that is located in the community of Diamond Springs in El Dorado County. The project will signalize and improve the intersection of Pleasant Valley Road (Route 49) and Patterson Drive (~ ED 10.704). Proposed improvements include widening the approaches to the intersection; addition of turn pockets; installation of traffic signals; installation of curbs, gutters, and sidewalks; grading and paving; drainage improvements; and minor landscaping. The project is estimated to cost $4.05 million and is programmed with State ($1,600,000) funds and Local ($2,450,000) funds. Construction is estimated to begin in fiscal year 2013/14.

In December 2007, the CTC considered relinquishment of right of way in the townsite of Diamond Springs, county of El Dorado, from approximately 213 feet west of the existing intersection of Route 49 and Pleasant Valley Road to 525 feet north of the existing intersection of Route 49 and Pleasant Valley Road and 256 feet east of the existing intersection of Route 49 and Pleasant Valley Road, consisting of superseded highway right of way (~ ED 11.871).

In May 2016, the CTC authorized $1,000,000 for a project in El Dorado County, on Route 49 from north of the intersection of Route 49 and Fowler Lane (~ ED 11.862) to Bradley Dr. (~ ED 12.364). Outcome/Output: Improve traffic safety and operations by realigning Route 49.

El Dorado to Auburn

A new Route 49 alignment is planned between Placerville and Coloma (~ ED 14.832 to ED 23.112) directly paralleling Cold Springs Road.

South Fork American River Bridge (~ ED 023.99)

In May 2015, the CTC approved for future consideration of funding a project in El Dorado County that will replace the South Fork American Bridge on Route 49 near the towns of Coloma and Lotus. The project is programmed in the 2014 State Highway Operation and Protection Program. The estimated cost is $20,817,000 for capital and support. Construction is estimated to begin in Fiscal Year 2015-16. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2014 State Highway Operation and Protection Program.

In June 2016, the CTC approved $16,593,000 for a project in El Dorado County on Route 49 near Coloma, from 0.1 mile east of Marshall Road to 0.3 mile east of Lotus Road. Outcome/Output: Provide seismic standards and structural integrity by replacing South Fork American River Bridge No. 25-0021 on new alignment, constructing retaining walls, installing drainage systems, and relocating utilities

Georgetown Bridge Debris (North Fork American River) (~ PLA 0.008)

In March 2023, it was reported that the Placer County Board of Supervisors unanimously approved a fund transfer agreement with Caltrans that permits it to receive funding allocated for the removal of Route 49 Bridge debris in the North Fork of the American River (~ PLA 0.008). The $8 million in funding was made available to Placer through Assembly Bill 178 within the California 2022-23 budget to “remove the steel and concrete wreckage of the former State Route 49 Bridge that lies in the American River.” The bridge broke into three pieces and was washed away in December 1964, when the partially constructed Hell Hole Dam failed during an atmospheric weather event. Just nine months later the Auburn Dam Project was passed by Congress and signed into law by President Johnson on September 2, 1965. The metal and concrete bridge debris deposited in the river channel and along its banks was left where it was because it was assumed the Auburn Reservoir would soon cover it under hundreds of feet of water. However, the debris creates a hazard to those who swim and boat this river segment in the heavily used Confluence area of the Auburn State Recreation Area. The receipt of the funds is the first step in getting the project underway and the execution of the transfer agreement will assist in receiving the $8 million. From there, Placer County will begin to evaluate the actual removal. They will do environmental studies, make sure it’s feasible and safe and start the process of working with stakeholders, regulatory agencies and to eventually be able to remove the debris. Due to the funding being a lump-sum bill, there is no option to increase the funds and the county would have to go back to the legislative advocacy process for a new allotment.

In August 2025, it was reported that a major project has begun to remove 750 tons of metal and concrete that had been sitting in the riverbed of the North Fork of the American River for decades. The debris is all that’s left after a Christmas storm destroyed the Georgetown Bridge near Auburn, in the Sierra Nevada foothills, 61 years ago. Torrential rain in the days before Christmas 1964 had caused rivers to swell and stoked fears of flooding across Northern California and the Sierra Nevada foothills. Higher up in the Sierra Nevada, on the Rubicon River, rain and snowmelt pounded against the Hell Hole Dam. But on the morning of Dec. 23, 1964, the partially built dam burst, releasing a “hurtling wall” of water downstream toward Auburn, where a surge of frothing, fast-moving water took out the Georgetown Bridge on Route 49, near the confluence of the North Fork and the Middle Fork of the American River. Twisted metal and concrete from the bridge sank beneath the water at the bottom of the North Fork of the American River. More than 60 years later, the remnants are still there. This includes bridge girders that are 10 feet tall and 200 feet long, stuck in the riverbed. There were plans to build another dam in Auburn, and at the time, officials thought the bridge debris would be far underwater from a new reservoir. But the dam was never built, and the debris remained in the river. In the fall of 2020, a nonprofit organization called Protect American River Canyons decided it was time to finally pull the bridge out of the water and resolve the underwater hazard. It worked with divers to survey the debris and spoke with Placer County officials about taking on the project. Former state Sen. Brian Dahle helped the county secure $8 million to remove 750 tons of metal and concrete that remain underwater. The first phase involves building a temporary ramp and a beach area so that crews can access the site and store heavy equipment throughout the project. During the project, a portion of the Calcutta Falls Trail and some roadside parking will be closed. Part of the river will be closed to the public, as well. The stretch between Old Foresthill Road Bridge and No Hands Bridge will be closed to water recreation.
(Source: SF Gate, 8/20/2025)

Although not directly on Route 49, there are plans to retrofit and upgrade the Foresthill Bridge (~ PLA 0.044). The bridge was constructed in 1973 for $13 million as a proposed rerouting of Route 49 to avoid low-lying areas that would be flooded when the Auburn Dam was completed. The dam, however, was cancelled and the connection to Route 49 was never constructed, leaving the bridge orphaned and maintained by Placer County. In February 2010, it was reported that the bridge was up for an estimated $71 million seismic retrofitting. Potential contractors were treated to an up-close view of the bridge and briefed on the scope of work to be done, including the complex job of painting the span without letting original lead-based paint particles drop into the river below. Bids were to be advertised in April 2010, and the contract to be awarded in May 2010. Construction could start in August 2010 and last until 2012.

Cool to Auburn Corridor (~ ED 34.546 to PLA 3.128)

In April 2023, it was reported that a multi-year study looking into a bevy of concerns regarding a stretch of Route 49 between Cool and Auburn has provided a list of potential fixes. Narrow roadways, tight turns, limited shoulders packed with parked cars, hikers and river-goers crossing the road to and fro and oversized trucks driving through tight turns all contribute to long drive times and raise the risk of possible traffic incidents on Route 49. The El Dorado County Transportation Commission, in partnership with California State Parks, Caltrans, El Dorado County and the Placer County Transportation Planning Agency, conducted a study after concerns were raised by local residents and authorities in early 2020. Trip data, collected using the Replica Data software platform, determined that travelers along the highway made trips with an average distance of 58 miles, with longer trips during peak summer months. The data suggested most travelers through the confluence area were likely not local residents and average vehicle occupancy was 1.6 people per vehicle. The Replica Data software platform collected information using cell phone location data from within the study corridor. Key pain points and potential solutions were identified through data collection, public workshops and surveys between 2021 and 2023. Completed in February 2023, the EDCTC’s final report is a set of suggestions and prioritized timelines; actual projects will require one or more of the agencies in the area to schedule, budget and plan them, and would need to go through a development process of possibly three to 10 years. Problems and projects identified include:
(Source: Mountain Democrat, 4/3/2023)

Trucking and Trucks. (Near Term) The highway in the area is only designated for use by trucks with a kingpin to rear axle length from 30 to 38 feet; data collected shows around 30% of trucks that traverse the corridor exceed those limits. Trucking as a business prioritizes short routes and quick delivery; if a route calls for going from Placerville to Auburn or vice versa, it would involve switching from US 50 to I-80 in Sacramento. Rather than take that long detour, truckers might opt for the shorter route along Route 49 either because their navigation software suggests it and they are unaware of truck size limits, or they know the limits but choose to take their chances. The EDCTC recommends two approaches to the issue of oversized truck travel. The first suggestion is installation of signage at key locations indicating that oversized trucks are not allowed; the second suggestion is a call for increased enforcement by California Highway Patrol officers paired with advocating that federal truck route designations be changed to not allow oversized trucks access to the Route 49 corridor. To avoid issues stemming from trucks that will need to turn around to avoid going down the corridor, the EDCTC has raised the possibility of installing a roundabout in Cool at the intersection of Route 49 and Route 193.
Evacuation Concerns. (Near Term) Evacuation preparedness is not within the explicit scope of the study but many of the suggestions are expected to be useful in hazard scenarios. Such suggestions include removing vegetation along the highway and parking lots on local roadways, placing permanent “no parking” signs at pullouts along the highway where overflow parking frequently occurs and installation of intelligent signage capable of informing visitors of parking availability or evacuation information in case of an emergency.
Transit Shuttles. (Near Term) A potential relief to parking woes could take the form of a shuttle service through the confluence area between Auburn and Cool. The EDCTC study concluded that a bus service could be fully subsidized for all 97 days of the summer season or all 104 weekend days of the year through collection of 50% of parking revenues during the summer season. A fare could additionally fund the service, with a potential lower ridership as opposed to a free shuttle. A short-term pilot shuttle program could aid in establishing ridership levels and demand prior to finalizing a long-term shuttle plan.
Parking Facilities (Mid Term) A 2019 California State Parks internal paper explored options with Caltrans and the U.S. Bureau of Reclamation regarding potential traffic safety solutions. The conclusion of the paper identified formalizing existing parking areas with painted stripes as a preferable solution to cars overcrowding the edges of the highway. The EDCTC study came to the same conclusion, determining that formalizing and paving undeveloped parking lots near the confluence would ease congestion. Fees could be implemented, with price structure consistent with the one used by State Parks. An area could be set aside specifically for emergency vehicles.
Pedestrian Safety (Mid Term) Installation of pedestrian crossings, ADA improvements and flashing beacons could aid in minimizing the chance for accidents. (Long Term) EDCTC indicated a pedestrian bridge along the highway could be a worthwhile project. Changes to existing intersections were also proposed, if warranted by traffic volume.
Roadway Safety. (Mid Term) For ease of use and safety, improved road striping alignment to correct shoulder width and installation of rumble strips at hairpin turns along the corridor have been identified as potential projects. The study also raised the possibility of coordinating with Caltrans and reducing speed limits on the highway near the confluence.

In June 2019, the CTC approved for future consideration of funding a project located on Route 49 in the city of Auburn in Placer County (03-Pla-49, PM 1.8/2.4). The project proposes to realign two reverse curves at the Route 49/Borland Avenue/Lincoln Way intersection. The project proposes to construct a roundabout facility and widen shoulder widths to meet the Highway Design Manual standards. The proposed project will address the need to reduce the number of collisions involving loss of control in the reversing curves and trailer off-tracking on narrow shoulders at tight radius curves. The project is currently programmed in the 2018 SHOPP for an estimated total of $8.9 million, which includes Construction (capital and support) and Right-of-Way (capital and support). Construction is estimated to begin in 2020. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2018 SHOPP.

In June 2022, the CTC approved a request for an additional $2,276,000 in Construction Capital for the SHOPP Safety Improvements project on Route 49, in Placer County, to award the construction
contract (03-Pla-49 2.2/2.4, PPNO 03-4785; ProjID 0316000077; EA 1H240). This project is located on Route 49 in the City of Auburn, at Lincoln Way, in Placer County. The project will replace the signalized intersection by realigning the roadway and constructing a roundabout. This safety improvement project will reduce the number of collisions experienced on this segment of Route 49. The project will reduce the potential for rear-end collisions and other collisions involving the loss of control in the reversing curves and will eliminate problems due to trailer off-tracking on the narrow shoulders in the tight radius curves. In June 2019, the project was programmed for $4,000,000 in Construction Capital and $1,300,000 in Construction Support in the SHOPP (Subprogram: Safety Improvements) for allocation in the Fiscal Year 2019-20. In June 2020, the project received a 16-month time extension for project expenditure for the Plans, Specifications, and Estimate phase. In August 2021, the project received a construction allocation for $4,745,000 in Construction Capital and $1,525,000 in Construction Support. In January 2022, the project received a six-month time extension for awarding the project contract; bids were opened in January 2022, and the amount required to award to the lowest bidder exceeded the amount available from the approved project allocation and G-12 allotment. In November 2021, the Department advertised the contract, with the bid opening in January 2022. The contract received four bids, however, the first and second-lowest ranked bidders did not meet the “good faith effort” for the Disadvantaged Business Enterprise (DBE) goals. The third lowest bidder is 42.0 percent above the Engineer’s Estimate (EE) and the fourth bidder is 52.6 percent above the EE. The lowest three bidders were contacted about their bids. Each of them explained that their bids are higher than anticipated due to the relatively smaller footprint of the project area, risks related to utility relocation during construction, the restrictions on the number of working days, and a slower production rate of work needed due to short shifts and staged work, which is reflected in the bid items related to sanitary sewer line relocation, traffic control, street sweeping, structural concrete items. In addition, each of the contractors stated that their bids reflected pressures related to the current supply chain issues, labor shortages due to the pandemic, a higher DBE recruitment goal, and current material price volatilities. The Department had anticipated a higher price for the elements of the roundabout by estimating the proposed scope of work based on historical unit prices and escalating them to the midpoint of construction. In addition, the Department included higher costs for the limitations of the footprint, utility relocation risks, and possible risks associated with constructability and traffic control. Although the project estimate was updated six weeks prior to the approval of the allocation by the Commission at the August 2021 meeting, when the supply chain issues and labor shortages were still dynamic, it is possible that the overall estimate was still undervalued as the current market trends are beyond those expectations. Due to the recently implemented higher DBE recruitment goal, no allowances were considered in the EE. The biggest cost differences between the EE and lowest bid are related to the unit prices for a number of bid items. In aggregate, these items amount to an increase of $1,629,000 over the EE. The remaining increase is due to minor unit price cost increases of other bid items. The Department has determined that these additional requested supplemental funds are in the best interest of the State to avoid delays in implementing this important safety improvement project and avoid the extra cost to the Department. The Department has exercised all feasible measures to minimize costs in carrying out work related to this project and has determined that this request is well-supported and is the only viable alternative available.

In October 2022, it was reported that construction had started on a $9.9 million roadway project that will improve a quarter-mile segment of Route 49 near Lincoln Way and Borland Avenue in south Auburn. The project will realign two reversing curves to improve sight distance and safety by reducing the sharpness of each curve. Additionally, the existing traffic signal at the Lincoln Way/Borland Avenue intersection will be replaced with a roundabout to improve safety and traffic flow. This safety project is the second of three Auburn-area projects that will improve the Route 49 corridor in Placer County. In spring 2022, Caltrans completed a $47.4 million roadway improvement and complete streets project between the I-80 separation and Dry Creek Road that widened shoulders, added sidewalks and new traffic signals and rehabilitated the roadway. A $26.7 million safety project is in development to add a median concrete barrier on Route 49 between Lorenson Road and Lone Star Road in North Auburn, with roundabouts providing operational improvements at the two intersections.

In April 2023, it was reported that preparation work was resuming for a roundabout at the gateway to the American River Canyon as utility contract work at the intersection of Lincoln Way and Borland Avenue intersection begins. This map, provided to the city of Auburn by the Caltrans contractor, outlines construction and traffic impacts expected as part of the American Canyon Roundabout work, which has restarted this week. The work is in preparation for Caltrans' $9.9 million roadway project that aims to improve a quarter-mile segment of Route 49 near Lincoln Way and Borland Avenue. The project will align two reversing curves to improve sight distance and safety by reducing the sharpness of each curve. The work will include replacing the Lincoln Way/Borland Avenue intersection with a traffic circle. After utility work is completed, Caltrans' can restart its efforts to install a traffic circle at the busy intersection, which is the gateway to recreational activities in the Auburn State Recreation Area. The project was previously paused due to the winter weather conditions.

In August 2024, the CTC approve a request for an additional $775,000 (11.0% increase) in Construction Capital for the SHOPP Safety Improvements project on Route 49, in Placer County. (EA 1H240, PPNO 4785). This project is located on Route 49, in the City of Auburn (City), at the intersection of Route 49 and Lincoln Way/Borland Avenue, in Placer County. The project will replace the signalized intersection by realigning the roadway and constructing a roundabout. In October 2016, the project was programmed for $1,697,000 in Construction Capital and $819,000 in Construction Support in the SHOPP for allocation in Fiscal Year 2019-20. In January 2019, the project was amended to increase Construction Capital to $4,000,000 and Construction Support to $1,300,000 due to the addition of scope to construct a roundabout. In June 2020, the project received a 16-month allocation time extension for the Construction phase. In October 2021, the project was allocated for $4,745,000 in Construction Capital and $1,525,000 in Construction Support. In May 2022, the project received supplemental funds in the amount of $1,306,000 in Construction Capital to award the contract. The project was then awarded for $6,051,000 in Construction Capital. In June 2022, construction began with 130 working days. In April 2024, the project received G-12 funds in the amount of $353,000 in Construction Support. The project cannot receive G-12 funds for Construction Capital due to the supplemental funds that were requested to award the project. The remaining funds are currently at $2,708,000 in Construction Capital and $707,000 in Construction Support. The project is 60 percent complete with 60 working days remaining. The planned Construction Contract Acceptance is scheduled for May 2025. A known risk has come to fruition as the project realized cost increases due to delays experienced by Pacific Gas and Electric (PG&E), Placer County Water Agency (PCWA), and the City in obtaining Maintenance Consent Letters (MCLs) from Union Pacific Railroad (UPRR) for the relocation of utility poles, water lines, and sewer lines. The Department did everything possible to avoid construction delays by obtaining an MCL for all of the transportation work within UPRR right of way and facilitating communication between UPRR and the utility companies. Utility Agreements were executed between the Department, PG&E, PCWA, and the City for the relocation of the utility-owned facilities within the project limits. These Utility Agreements allowed the Department to issue right of way certification and the project to proceed to Ready to List in June 2021. However, delays have persisted because the utility-owned facilities are located within UPRR right of way where the utility companies were required to apply individually for their own MCLs and subsequent Right of Entry (ROE) permits. The utility MCLs are outside of state control as they are agreements between two external independent entities so the Department cannot make these types of requests for the utility companies. Despite the Department’s efforts to facilitate timely coordination of these agreements, the time to process the agreements and perform the relocation work has exceeded the estimated project schedule. The PG&E overhead utility pole relocation work specified in this project was planned to occur between December 2021 and February 2022 as stated in the project’s special provisions. PG&E relocation did not proceed as scheduled due to a delay in obtaining a ROE Agreement with UPRR. PG&E’s utility relocation work did not begin until April 2023, more than 14 months later than stated in the special provisions. This work continued sporadically until the last pole was removed in January 2024. The PG&E relocation work delayed the contractors’ operations causing increased costs in stormwater maintenance, labor costs, and inefficiencies.

In June 2025, it was reported that construction was continuing along Route 49 at Lone Star Road for a $38 million safety barrier and roundabout project. Crews were reducing northbound and southbound Route 49 to one lane in each direction, with restrictions on turns. There were also SB lane reductions planned. Additional lane reductions were scheduled for August at the intersection of Lorenson Road/Florence Lane and in September at the intersection of Lone Star Road. The extended lane reductions allowed room for crews to continue working safely on the new roundabout. The project is expected to be completed by fall 2025. At that time, the 1.3-mile stretch along Route 49 will include a concrete median barrier and roundabouts at the Lorenson Road/Florence Lane and Lone Star Road intersections. Additional work will include new pavement, striping, curb gutters, sidewalks, lighting and signage.

In October 2025, the CTC approved a request for an additional $850,000 (14.0 percent increase) in Construction Capital for the SHOPP Safety Improvements project on Route 49, in Placer County. (EA 1H240, PPNO 4785). This project is located on Route 49, in the City of Auburn (City), at the intersection of SR 49 and Lincoln Way/Borland Avenue, in Placer County. The project will replace the signalized intersection by realigning the roadway and constructing a roundabout. The cost increase is due to delays experienced by the City in obtaining Maintenance Consent Letters (MCL) from Union Pacific Railroad (UPRR) Company for the relocation of sewer lines. The Department obtained an MCL for all transportation work within UPRR’s right of way. Utility agreements were made with City for the relocation of their facilities within the project limits. Since the utility facilities were located within UPRR’s right of way, the utility owners were required to apply for their own MCLs and subsequent right of entry permits, since the Department cannot make the requests on behalf of the utility companies. The utility agreements allowed the Department to issue a right of way certification and the project to proceed to construction. SHOPP Update: $850,000. 03-Pla-49 2.2/2.4.

In November 2025, it was reported that construction has started in Auburn on the roundabout at the intersection of Lincoln Way/Borland Avenue as part of the $13.1 million American Canyon Roundabout Project. Lamon Construction Co., Inc. of Yuba City is the prime contractor for the project, which will realign two reversing curves to improve sight distance and safety by reducing the sharpness of each curve. Additionally, the existing traffic signal at the Lincoln Way/Borland Avenue intersection is being replaced with a roundabout to improve safety and traffic flow.

In March 2026, it was reported that the $13.1 million safety and mobility project along Route 49 in Auburn has been completed, marking the latest in a series of improvements aimed at enhancing traffic flow and reducing collisions in the corridor. The project, known as the American Canyon Roundabout Project, included the realignment of two reversing curves to improve sight distance and reduce weaving by drivers. Crews also replaced a signalized intersection at Route 49 and Lincoln Way/Borland Avenue with a new roundabout designed to improve traffic circulation and safety. The roundabout project is the third major effort completed in the Auburn area to improve the Route 49 corridor. Earlier in 2026, Caltrans finished a $33.2 million safety barrier project that installed a concrete center divider between Lone Star Road and Lorenson Road/Florence Lane, along with two additional roundabouts. In 2022, the department said that crews also completed a $47.4 million roadway and “complete streets” project between I-80 and Dry Creek Road. That work included widening shoulders, adding sidewalks, installing new traffic signals and rehabilitating pavement. Construction is ongoing for another project in partnership with the Placer County Transportation Planning Agency. Officials said that the $14.4 million effort will close sidewalk gaps by adding nearly 10,000 feet of new walkways, upgraded curb ramps, multiple crosswalks across Route 49 and a pedestrian bridge over Rock Creek. Officials expect that project to be completed this summer.

In June 2026, the CTC approved a request for an additional $1,300,000 in Construction Capital to close out the construction contract. This project is located on Route 49, in the City of Auburn, at the intersection of Route 49 and Lincoln Way/Borland Avenue, in Placer County. The project will replace the signalized intersection by realigning the roadway and constructing a roundabout. The cost increase was due to the acceleration of the construction schedule, traffic detours that were needed through County roads, sewer line relocation that was more complex than anticipated, and addressing unanticipated drainage deficiencies.

In May 2009, the CTC relinquished right of way in the city of Auburn on Route 49, under terms and conditions as stated in the relinquishment agreement dated April 14, 2009, determined to be in the best interest of the State. Authorized by Chapter 635, Statutes of 2008, which amended Section 349 of the Streets and Highways Code. (~ 3-Pla-49-PM 2.52/3.0)

Route 49 in Auburn In February 2012, the CTC adopted a routing for Route 49 in the city of Auburn (~ PLA 3.09 to PLA 3.276). The purpose of this route adoption is to address the lack of continuity of Route 49 through the City of Auburn. On August 30, 2008, the Governor signed Assembly Bill 1915 which amended Section 349 of the Streets and Highways Code and provided the authority to relinquish a portion of Route 49 within the City of Auburn. On May 14, 2009, at the request of the City of Auburn and the California Department of Transportation (Department), the California Transportation Commission (Commission) relinquished a portion of Route 49 to the City of Auburn. The relinquished portion extended from the I-80 interchange, along south Grass Valley Highway, east on Lincoln Way and east on High Street to the intersection with Elm Avenue. This stretch of highway is the main thoroughfare through downtown Auburn and was part of a revitalization project proposed by the City called Streetscape Project for Lincoln Way and High Street. Phase 1 of this project was completed on June 28, 2010. The City also wanted control over future projects proposed for construction and to limit the amount of traffic and speed within the downtown area. The City’s General Plan identifies this route as a city street with multi-purpose mixed use. This route adoption as a conventional highway will allow Route 49 to reconnect to I-80 via Elm Avenue. The portion of Elm Avenue to be adopted is 0.3 mile long and is classified as an urban minor arterial. It is a four-lane arterial with a 12-foot median, 5-foot shoulders with curb, gutter and sidewalks on both sides of the road. Access to Elm Avenue between Tuttle Street and the westbound I-80 on ramp is controlled and the median is used as left turn lanes. East of Tuttle Street to the intersection of High Street / Route 49, the 12-foot median becomes a two-way left turn lane and there are several driveways serving local businesses. This section does not have any shoulders, but continues the curb, gutter and sidewalks from the previous section. The portion of Elm Avenue from the I-80 on ramp to the intersection with Route 49 is not included in this adoption, thus maintaining a gap in Route 49 continuity, albeit a smaller gap. Continuity can be obtained through the designation of I-80 between the Elm Avenue and the Grass Valley Highway interchanges as I-80/Route 49. Elm Avenue currently serves as the preferred truck route for truck traffic travelling along Route 49 through the City of Auburn. Trucks travelling south from Grass Valley predominately turn left on Elm Avenue to avoid downtown and then another left on High Street to get back on Route 49. Trucks travelling on I-80 predominately take the Elm Avenue off-ramp to access southbound Route 49. To access northbound Route 49 from I-80, trucks may either use Elm Avenue or Route 49 (Grass Valley Highway). For trucks travelling north from El Dorado County, the preferred truck route diverges from Route 49 once they enter the city due to a tight turning radius that exists at the corner of existing Route 49 and Elm Avenue. Currently, at this location, there are “Truck Route” signs placed by the City to direct trucks to turn left on Lincoln Way and then right on Elm Avenue. On December 12, 2011, the City of Auburn passed Resolution No. 11-123 approving the proposed Route 49 Route Adoption along Elm Avenue.

Naming

Much of this route is named the "Gold Country Highway" or the "Golden Chain Highway". It was named for its location, because it links historic towns and points of interest in California's gold country. The name "Golden Chain Highway" seems to have been popularized by tourist organizations on promotional materials for the highway (such as the "Golden Chain Council of the Mother Lode"), and subsequently on websites promoting the highway.
(Image source: Drive Highway 49, California's Golden Chain)

The portion of this route between Sonora and Auburn (~ TUO 17.969 to PLA 1.256) is officially named the "Mother Lode Highway", per Chapter 839 in 1921. It was named for its location. The "Mother Lode Highway", named in 1921, connects towns and points of interest in California's gold country.

The portion of Route 49 one mile before and after its intersection with Parrott's Ferry Road, in Tuolumne County (~ TUO 19.394 to TUO 21.394)is officially named the "Deputy Dave Grant Memorial Highway". This segment was named in memory of Deputy David P. Grant, a 15 year veteran of the Tuolumne County Sheriff's Department with more than 26 years of law enforcement experience. During the late morning of May 31, 2004, Deputy Grant suffered fatal injuries responding to a "plane down" call near the town of Columbia. While responding to the call at a high rate of speed, Deputy Grant's vehicle swerved to avoid colliding with two other vehicles, left the roadway, and struck a tree. Deputy Grant was critically injured and transported to the Sonora Regional Medical Center where, surrounded by family and fellow deputies, he succumbed to his injuries. This was the first loss for the Tuolumne County Sheriff's Department in more than 37 years. At the age of 16, David P. Grant served as an Explorer Cadet with the Sonora Police Department; and was sworn in as a Sonora police officer in 1978. Desiring to broaden his experience in a larger department, Deputy Grant accepted an appointment with the Oceanside Police Department in 1981 and served the City of Oceanside with distinction for eight years. He was sworn in as a Tuolumne County Deputy Sheriff on October 9, 1989. Named by Assembly Concurrent Resolution (ACR) 132, Resolution Chapter 105, on 8/16/2006.

The segment from the southern city limit of the City of Jackson to the intersection of Route 88 (~ AMA 2.266 to AMA 4.013) is officially named the "John C. Begovich Memorial Highway". John Begovich was an elected public official from Amador County. He was born on January 17, 1916, in Jackson Gate, California. He graduated from Sutter Creek High School and attended Sacramento Junior College and was a champion athlete at both institutions. In 1942, he enlisted in the United States Army where he rose to the rank of second lieutenant and earned 13 decorations, including the silver star, the bronze star, and three purple hearts. In 1945, he returned to Amador County and was selected to be the county Veterans Service Officer and County Civil Defense Director. In 1955, he was appointed judge in the Amador County Judicial District while retaining his position as Veterans Service Officer. In 1960, he was elected as Senator from the 9th Senatorial District serving Amador and El Dorado Counties and worked on numerous issues important to his constituents and the state, including the bistate park system within the Tahoe Basin, highway improvements, the creation of a second department of the Superior Court for El Dorado County, and a $250,000,000 veterans bill. In 1966, he was appointed by President Lyndon B. Johnson as one of four United States Federal Marshals in the State of California, serving in that capacity until 1970. In 1976, he was elected Supervisor of District 1, Amador County, where he made care of the elderly residents of the county one of his primary concerns. He was reelected as supervisor in 1980, 1984, 1988, and 1992. He died on November 2, 1999. Named by Assembly Concurrent Resolution 139, Chapter 120, August 30, 2000.

America's Heroes - Veterans Memorial Highway The portion of Route 49 from Valley View Way PM AMA R7.298 to approximately PM AMA R10.560 before the Jay-D Ornsby-Adkins Bridge (bridge number 26-0043), located at post mile R10.576, in the County of Amador is named the "America’s Heroes–Veterans Memorial Highway". It was designated to appreciate, admire, and honor the men and women who have served in the Armed Forces of the United States of America to protect and defend our country and the freedom, rights, and privileges enjoyed by all Americans. Nearly two million veterans reside in the State of California, and the County of Amador is home to many of these brave and honorable individuals. This was an indication that the state assembly intends to make it a priority to fully support our state’s veterans in ways that commemorate their great sacrifice. Named by Assembly Concurrent Resolution (ACR) 165, Chapter 125, Statutes of 2016, on August 16, 2016.

Jame E. Machado The intersection of Route 49 and Elm Avenue in the City of Auburn (~ PLA 2.526) is named the "James E. Machado Memorial Intersection". It was named in memory of James E. Machado, a deputy sheriff with four years of service with the Placer County Sheriff’s Department, who was shot and killed on July 13, 1978, with his own service weapon, in a struggle with an escaped mental patient. The altercation occurred on the shoulder of the northbound lanes of State Highway Route 49 at Elm Avenue in the City of Auburn. With the help of citizens who witnessed the shooting, the suspect was quickly located by officers of the California Highway Patrol and an officer of the Auburn Police Department. The suspect confronted the responding officers with Deputy Machado’s service weapon, and was subsequently killed when the officers fired several rounds at the suspect. Law enforcement officers from throughout the state attended Deputy Machado’s funeral, and he was posthumously awarded the Placer County Sheriff’s Purple Heart. Named by Senate Concurrent Resolution 114, Resolution Chapter 102, on August 7, 2014.

Named Structures

[Stevenot Plaque] Bridge 32-0040 over the Stanislaus River in Tuolumne and Calaveras counties (~ R027.28) is named the "Archie Stevenot Bridge". It was constructed in 1976, and was named by Senate Resolution 338, Page 4758, in 1988. Archie Stevenot (d. 1968), miner, cowboy, rancher, postmaster, and ox team swamper, helped found the California State Chamber of Commerce and was officially named "Mr. Mother Lode" by the California legislature. He was also the founder of the "Mother Lode Association" in 1919, which was the first highway association and promoted the assignment of the number "49" to Route 49.

Jan D Ornsby-Adkins The Route 49 Amador Creek Bridge, Bridge No. 26-0043 (AMA R010.56), is named the "Jay-D Ornsby-Adkins Bridge." This bridge was named in memory of Jay-D Ornsby-Adkins, born on December 9, 1985, in Middle Swan, Western Australia. He attended Ione Elementary School in Ione, Amador County, and graduated from Independence High School in Sutter Creek, Amador County, in 2005. He pursued a career in the United States Army and graduated from basic training on December 8, 2006, at Ft. Knox, Kentucky. He was assigned to the Delta Company 1st Battalion, 15th Infantry Regiment, at Ft. Benning, Georgia, where he continued to train, advance his skills, and prepare for combat, and earned the expert badge for grenade, rifle sharpshooter, and pistol marksman. On March 9, 2007, Jay-D Ornsby-Adkins was deployed to Iraq as a member of the Delta Company 1st Battalion, 15th Infantry Regiment; and on April 28, 2007, while on patrol, Private First Class Ornsby-Adkins and three other members of his unit died in combat. Named by Senate Concurrent Resolution (SCR) 84, Resolution Chapter 86, on 7/10/2008.

Bridge 26-0017, PM AMA 012.14, commonly known as the "Rancheria Creek Bridge", was officially named the "Amador County Veterans Memorial Bridge". Named by Senate Concurrant Resolution 43, Chapter 106, in 1997.

This route also had the following Safety Roadside Rest Areas:

Carson Hill, in Calaveras County, 4 mi S of Angels Camp (~ CAL 3.712), which is no longer in the state inventory of safety roadside rest areas.

Scenic Route

[SHC 263.4] Entire portion: Route 120 to Route 20 near Grass Valley.

Although this segment is eligible for Scenic Highway status, it has not yet met the criteria to be officially designated as Scenic Highway.

Freeway

[SHC 253.4] From Route 108 south of Jamestown to Route 108 near Sonora; and from Route 88 near Jackson to Route 50 near Placerville. These segments were added to the Freeway and Expressway system in 1959.

Alternate Routes

The following cities within this segment sign the route to make distinction between "Historic" Route 49 and "Bypass" Route 49:

San Andreas (~ CAL 19.379)
Mokelumne Hill (~ CAL 27.773) [although the "historic" routes points to the business district, which wasn't historically part of the route]

The following communities do not have historic or bypass signage, but do have streets named "Old Highway 49" (or something similar):

Sutter Creek
Amador City

Post 1964 Signage History

▸As defined in 1963, this was a single segment running from "Route 120 to Route 20 via Sonora, Angels Camp, San Andreas, Jackson, El Dorado, Diamond Springs, Placerville, and Auburn." Before the year was out, this was split into two segments by Chapter 1698: "(b) Route 120 to Route 80 in Auburn via the vicinity of Sonora; via Angels Camp, San Andreas, and Jackson; via the vicinity of El Dorado, Diamond Springs, and Placerville. (c) Route 80 near Auburn to Route 20."

▸In 1984, Chapter 409 changed the wording of the terminus to "Route 80 near Auburn to Route 20 in Grass Valley."

The very high Foresthill Bridge for Foresthill Road over the American River was built in the 1970s as part of construction for the abandoned Auburn Dam project; the bridge was built in the case that Old Foresthill Road and Route 49 would be flooded out by the then-forthcoming Auburn Reservoir (which never came to fruition). According to Travis Mason-Bushman, after the construction of the dam, Route 49 would've been placed on the bridge, but as construction halted in 1976, this never materalized (although some officials in Auburn still hope for the dam to be built). Currently, this bridge (located about a half mile from Route 49 on Foresthill Road) is the third-highest in the United States.

A discussion of the Highways to Boulevards program during the March 2022 CTC meeting identified the following segment(s) as potential Highways to Boulevards conversion projects: Route 49 North of Bell Road (~ PLA 6.391); Route 49 near Palm Avenue (~ PLA 3.787)

Pre 1964 Signage History

In 1934, Route 49 was signed along the route from Jct Route 140 at Mariposa to Jct. Route 24 (now Route 70) near Reno Jct, via Sonora, Jackson, and Nevada City. It was LRN 17, and was defined in 1909.

Rte 49 Fwy Rescission Rock Creek to Bear Creek In 1962, the CHC adopted a freeway routing for 4.5 mi between Rock Creek and 0.2 mi S of the Nevada County Line at the Bear River. In 1975, the CHC published a notice of intent to abandon this freeway adoption. It was not scheduled for construction in the foreseeable future and no right of way had been acquired.
(Source: Sacramento Bee, 7/10/1975, via Joel Windmiller, 2/25/2023)

Proposed Freeway Routing: Placer County Line to Limekiln Road In 1954, it was reported that a freeway routing for Route 40 between a point near the Placer County line (~ PLA 11.308) to 1.5 mi S of Rattlesnake Creek (~ NEV 7.214) had been adopted. The route follows in general the existing highway, with minor changes to straighten curves and eliminate humps. However, given the lack of interchanges as of 2023, it appears the freeway was never constructed.

Status

In December 2014, the CTC authorized relinquishment of right of way in the city of Auburn along Route 49 at Fulweiler Avenue (~ PLA 3.469), Palm Avenue (~ PLA 3.782), and Persimmon Drive (~ PLA 3.927), consisting of collateral facilities. The City, by cooperative agreement dated April 26, 2004 and by letter signed June 26, 2013, agreed to waive the 90-day notice requirement and accept title upon relinquishment by the State. The County, by cooperative agreement dated June 8, 2004 and by letter signed September 19, 2013, agreed to waive the 90-day notice requirement and accept title upon relinquishment by the State.

Highway 49 Safety Study (~ PLA 3.26 to NEV R13.705)

In November 2020, it was reported that Caltrans was releasing the State Route (SR) 49 Safety Assessment Report (http://www.hwy49safety.com/) highlighting safety findings and proposed improvements to the corridor between I-80 in Auburn and McKnight Way in Grass Valley. In February 2020, a team including Caltrans and its transportation partners embarked on a safety assessment of the Route 49 corridor to identify safety-related improvements that could be installed in the very near term, identify enhancements that could be added to planned construction projects, and plan longer-term projects to improve corridor safety. For analysis purposes, the team divided the corridor into four segments of similar characteristics based on features that include population density, traffic volumes and the rural or urban nature of the area:
(Source: Yubanet.Com, 11/10/2020; State Route 49: I-80 to McKnight Way Draft Safety Assessment Report)

Segment 1: Interstate 80 to Dry Creek Road
Segment 2: Dry Creek Road to Wolf Road/Combie Road
Segment 3: Wolf Road/Combie Road to Allison Ranch Road/La Barr Meadows Road
Segment 4: Allison Ranch Road/La Barr Meadows Road to McKnight Way

The existing safety features and collision history of each segment were assessed and used to outline recommendations for improvements to the corridor. There were specific key issues identified for the entire corridor, as well as for each segment. Examples include:
(Source: State Route 49: I–80 to McKnight Way Draft Safety Assessment Report)

Corridor: More collisions occur during the fall, more collisions occur on weekdays than on weekends, more collisions occur during the PM hours (noon to midnight) than the AM hours (midnight to
noon).
Segment 1: Auto-ped collisions are high, Congestion-related collisions are high, Making left turns from unsignalized side streets requires driver patience; drivers have difficulty entering the roadway at unsignalized intersections
Segment 2: Fatality rate is higher than statewide average, but other collision rates are lower; • Drivers have difficulty entering the roadway at unsignalized intersections due to limited sight distance at some intersections; southbound congestion at Dry Creek Road contributes to collisions.
Segment 3: Southbound congestion at Wolf Road/Combie Road and Alta Sierra Drive contributes to collisions; there is a lack of passing opportunities 3.7 miles northbound and 4 miles southbound between
about Cameo Drive and Mother Lode Road/Oak Drive
Segment 4: Collision history shows higher concentrations at lane drop merge areas; drivers have difficulty entering the roadway at unsignalized intersections due to limited sight distance

The report also identifies near and long term safety improvement recommendations in both non-engineering and engineering domains. The former stresses the education and enforcement options available. The engineering options emphasize signage, markings, and simple roadway features in the near term. Long term engineering measures are more substantial: raised medians, turn pockets, wider roadways, changeable message signs, wildlife crossings, vehicle pullout areas, intersection improvements, and much more.

Highway 49 Rehabilitation Project (~ PLA 3.26 to PLA 7.426)

Rte 49 Auburn Gap Closure In February 2019, it was reported that the Highway 49 Gap Closure Project will close the gaps between sidewalks in the approximately 4.4-mile Route 49 corridor between I-80 and Dry Creek Road (~ PLA 3.26 to PLA 7.426), creating a continuous sidewalk on at least one side of the highway. This project is just one of several on-going efforts to improve Route 49 by constructing sidewalks, bike lanes, and operational improvements. In spring of 2017, Caltrans was scheduled to repair sections of Route 49 within the greater Auburn area. During the planning process, Caltrans acquired additional funding to add bike lanes in both directions and sidewalks in certain segments, creating what’s known today as the “Highway 49 Rehabilitation Project.” While the additional money expanded the scope of improvements to Route 49, sidewalk gaps would still remain in the corridor, even after the Route 49 Rehabilitation . In 2018, Placer County constructed approximately one-half mile of sidewalks on Route 49 in front of the Bel Air Shopping Center between New Airport Road and just north of Willow Creek Drive. At the request of the City of Auburn and Placer County, PCTPA agreed to lead a multi-agency effort to determine where and how to fill in the remaining sidewalk gaps. The Route 49 Sidewalk Gap Closure project creates a “shelf ready” project by completing the required environmental and design work. This project was originally incorporated into the Placer County Measure M transportation sales tax measure that failed back in November 2016. The Measure M sales tax measure would have constructed sidewalks, incorporated traffic signal synchronization, landscaping, and operational improvements throughout the corridor. Without the passage of Measure M, PCTPA looked to other funding opportunities such as the extremely competitive Statewide Active Transportation Program (ATP) grant to deliver a scaled down version of the original project. At the California Transportation Commission’s (CTC) January 26, 2019 meeting, the CTC approved a $14.4 million dollar grant to construct approximately 2.8 miles of sidewalk. The grant also included funding to develop and implement a Safe Routes to School program at six area school in partnership with the Placer County Department of Public Health. The schools in the corridor include Rock Creek Elementary, Auburn Elementary, E.V. Cain Middle School, Maidu High Independent Study, Confluence High School and Placer High School.

In June 2019, it was reported that Caltrans will begin construction in mid-June 2019 on the $40.5 million project in Auburn, with funding provided by Senate Bill 1 (SB 1), the Road Repair and Accountability Act of 2017. The project, which stretches 4.4 miles from the I-80/Route 49 interchange to Dry Creek Road, will rehabilitate existing pavement and drainage, improve operational features and upgrade pedestrian and bicycle facilities. Class II bicycle lanes will be installed northbound and southbound on Route 49 between Elm Avenue and Dry Creek Road, with bike timing loops at each signal to assist bicyclists traveling the four-mile stretch. The project has been awarded to Flatiron West, Inc. In addition to improving the highway’s durability and ride quality with 21 lane miles of a Hot-Mix Asphalt (HMA) overlay, construction crews will install new traffic signals at Locksley Lane and Shale Ridge Road. Highway shoulders and pedestrian facilities will also be upgraded to comply with the Americans with Disabilities Act (ADA). Construction is anticipated to be completed in summer 2020.

In December 2014, the CTC authorized relinquishment of right of way in the county of Placer along Route 49 from Marguerite Mine Road (~ PLA 4.554) to Bell Road (~ PLA 6.382), consisting of collateral facilities.

Placer 49 Safety Barrier Project / Roundabout Plan (03-Placer-49 PM R8.7/R10.6)

Auburn to Grass Valley Roundabout Plan (03-Placer-49 PM R8.7/R10.6) In August 2017, it was reported that Caltrans had presented a concept — emphasis on the concept part — called the Highway 49 roundabout plan. That concept envisions a center barrier from North Auburn (~ PLA 4.676) to Grass Valley (~ NEV R14.318). It would feature roundabouts, placed every 1¼ to 1½ miles, enabling drivers to leave the highway or change direction on the road. Traffic lights wouldn't exist. The roundabouts would take their place. Left-hand turns from a driveway onto the highway could no longer occur. Instead motorists would turn right and follow the road to the nearest roundabout, where they could turn around. The concept permits creation of a center median that many people want. There is no price tag on this idea, nor has there been any engineering work.
(Source: The Union, 8/15/2017; Image source: Yubanet.Com 5/19/2021 and Caltrans Postmile Tool)

In October 2017, the roundabout notion reappeared, when Caltrans presented initial design graphics and a more in-depth look at the proposed plan. Roundabouts on Route 49 would allow drivers prevented from turning left by the proposed concrete median barrier to reverse course "in an efficient and safe manner as well as address a frequently voiced community concern — speeding motorists," the department said in a news release. Ten safety improvement projects on Route 49 are planned by Caltrans over the next six years, Whitmore said, in addition to increased funding for California Highway Patrol enforcement of traffic laws. Those projects include installing flashing beacons at Alta Sierra Drive (~ NEV 9.213), upgrading intersection lighting at Brewer Road, installing radar speed feedback signs at various locations, and widening shoulders in some areas, among others.

In May 2021, it was reported that Caltrans was conducting virtual public meetings seeking community comments about the proposed safety improvement project on Route 49 in Placer County. The purpose of the safety project is to reduce cross centerline collisions by installing a concrete median barrier on Route 49 between Lorenson Road/Florence Lane and Lone Star Road in Placer County. To account for out-of-direction travel by the construction of a median barrier, Caltrans is proposing to install roundabouts or traffic signals at the Lorenson Road/Florence Lane and Lone Star Road intersections to accommodate U-turn movements.

In October 2021, the CTC approved the following project for future consideration of funding: 03-Pla-49, PM R8.7/R10.6. Placer 49 Safety Barrier Project. Construct a concrete median barrier and other safety features on Route 49 in Placer County. (MND) (PPNO 4787) (SHOPP) (Related Item under Ref. 2.5b.(2)). This project is located on Route 49 near Auburn, between Lorenson Road/Florence Lane and Lone Star Road, in Placer County. The Department proposes to construct a concrete median barrier on Route 49 to reduce the number and severity of cross median collisions within this segment. In addition, safe turning movements, including U-turn movements for out-of-direction travel as a result from the construction of the concrete median barrier, will be installed. This project is currently programmed in the 2020 SHOPP for a total of $35,670,000, which includes Construction (capital and support) and Right of Way (support). Construction is estimated to begin in 2022. The scope, as described for the preferred alternative, is consistent with the project scope as programmed by the Commission in the 2020 SHOPP. A copy of the MND has been provided to Commission staff. The project will result in less than significant impacts to the environment after mitigation.

In August 2023, the CTC approved the following project for future consideration of funding: 03-Pla-49, PM R8.7/R10.6. Placer 49 Safety Barrier Project. Construct a concrete median barrier and two roundabouts in Placer County. (MND Addendum) (PPNO 4787) (SHOPP). The project is located on Route 49, from postmile (PM) R8.7 to PM R10.6, in Placer County. The Department proposes to construct a concrete median barrier and two roundabouts. The project is currently programmed in the 2020 State Highway Operation and Protection Program (SHOPP) for a total of $35,670,000, which includes Right of Way (Support and Capital) and Construction (Support and Capital). Construction began in 2022-23. The scope, as described for the preferred alternative, is consistent with the project scope as programmed by the Commission in the 2020 SHOPP. A copy of the MND has been provided to Commission staff. The Commission approved the project for future consideration of funding on October 13, 2021, under Resolution E-21-89. Since the approval of the MND there have been changes to the project and an Addendum pursuant to the California Environmental Quality Act (CEQA) was prepared. These changes include drainage improvements including roadside ditch realignment and grading at PM R9.30, PM R9.90, and PM R9.94. The upgraded drainage elements at the three new locations would have impacts to ephemeral (0.010 acre) and intermittent (0.002 acre) drainages and scrub shrub wetlands (0.030 acre). The drainage element upgrades would include side ditch realigning and grading for positive drainage and graded into a trapezoidal ditch to accommodate drainage flows. The project activities would consist of vegetation removal and roadway excavation. The decision was made to prepare a CEQA Addendum because the original MND had discussed and analyzed impacts to the same biogeographical areas. The project changes were deemed less than significant. The impact at these three locations to upgrade drainage elements and roadside ditch realignment was not considered a significant increase in impacts. The project changes do not meet the criteria outlined in CEQA Guidelines Section 15162 to prepare a Subsequent MND. The Department subsequently completed an Addendum to the MND pursuant to CEQA. The Department has approved this project for construction. This approval and the Addendum will satisfy the environmental requirements for this stage of the planning process.

In August 2023, the CTC approved a request for an additional $150,000 in Plans, Specifications and Estimate (PS&E) and $50,000 in Right of Way (RW) Capital Outlay Support (COS), for the SHOPP Safety Improvements project on Route 49, in Placer County, to complete the PS&E and RW phases. This project (03-PLA-49 R8.7/R10.6, PPNO 03-4787; ProjID 0319000004; EA 4H600) is located on Route 49, near the City of Auburn (City), south of Lorenson Road/Florence Lane to north of Lone Star Road, in Placer County. The project will construct a concrete median barrier and two roundabouts. In August 2019, this project’s PS&E and RW phases were programmed for $940,000 and $900,000 in the SHOPP for completion in Fiscal Year 2021-22. In June 2020, the project received a 4-month allocation time extension for PS&E and RW Support. In October 2021, the project received a PS&E allocation for $940,000 and RW allocation for $900,000. In March 2022, the project received G-12 funds in the amount of $294,000 for PS&E. In October 2022, the project received G-12 funds in the amount of $290,000 for RW Support. In June 2022, the project received a 20-month allocation time extension for the construction phase. The PS&E phase is currently 90 percent complete and the RW phase is 75 percent complete. The remaining budget is $46,000 for the PS&E phase and $130,000 for the RW phase, which is insufficient to complete the phases. The project completed Ready to List in June 2023, and is anticipated to complete the remaining PS&E activities by January 2024. The project realized cost increases to the PS&E and RW phases due to the complex design and construction staging, challenging right of way acquisition efforts involving multiple parcels, and additional coordination with the permitting agencies. The project location is in a rural setting north of the City with rolling hill terrain. This segment of SR 49 is a 5-lane highway with a 65 miles per hour posted speed. The proposed 1.3-mile median barrier prevents cross-median collisions with roundabouts at both ends of the median barrier to limit out-of-direction travel by providing legal U-turn movements and as traffic calming measures. The roundabouts are designed for two through lanes of traffic and a turning radius sufficient for California legal trucks. Constructing the roundabouts with a design speed of 25 miles per hour on a 65-mile per hour 5-lane highway required complex construction staging and traffic handling. The large footprint required to build the roundabouts resulted in impacts to adjacent property owners, utilities, and environmentally sensitive areas. Additional design work was done to reduce the roadway footprint and the amount of area required for right of way acquisition, reduce utility conflicts, and lessen impacts on environmentally sensitive areas. Right of way was impacted by negotiations with a property owner for permanent acquisition and utility easements on four of their parcels. The condemnation process was required to obtain possession of the property owner’s multiple parcels.

In March 2024, it was reported that with approval from the California Transportation Commission in December, a $101.5 million project will widen Route 49 between Ponderosa Pines Way north of Wolf Road in Grass Valley, as well as add shoulders and a center two-way left turn. The project is geared to allow safer entrances and exits from the highway and also improve evacuation times in the event of wildfire. The project is one of several planned for Highway 49, aligning with a Caltrans’ State Route 49 Comprehensive Multimodal Corridor Plan to address “regional and interregional safety, congestion, accessibility, goods movement, economic development, land-use efficiency, public health, air quality, and greenhouse gas emissions for Route 49 in Nevada and Placer counties.” With the upcoming work slated for the main artery into western Nevada County, local, regional and state officials plan to eventually widen Route 49 to two lanes in both directions between Grass Valley and Auburn. Among Caltrans planned projects in Placer County to improve safety, work is slated to start in April and be completed in November 2025 to install roundabouts at intersections with Lorenson Road and Lone Star Road, with a concrete median barrier extending the 1.3-mile stretch between them.

In January 2026, it was reported that Caltrans had released the Draft Environmental Document (DED) for the proposed $107.4 million project. Public information meetings were in progress, and the document was open for review and comments through January 12, 2026. The climate resiliency project proposes to widen shoulders by 12 feet along southbound Route 49 from the Wolf Road/Combie Road intersection to Ponderosa Pines Way, as well as the addition of an 8-foot wide shoulder on the northbound side of Route 49. Bottleneck locations along the eight-mile stretch have been identified as problematic. The project will also install a two-way left turn center lane throughout the eight miles, widen the existing bridge at South Wolf Creek, and construct a new bridge at Rattlesnake Creek, along with an upgrade of the roadway pavement, guardrails, and culverts. Construction for the evacuation project is expected to be completed in December 2030. The right of way team is scheduled to take actions in April 2026 in the form of contacting property owners who will be affected by the design. Caltrans may also contact property owners and ask for a temporary construction easements. The project is still in the Project Approval and Environmental Document (PA&ED) phase until the end of January 2026, and then in March 2026 it is expected to go onto the design phase.

In March 2025, the CTC approved a request for an additional $700,000 (23.7% increase) in Pre-Construction Support, PS&E phase and $60,000 (3.0% increase) in Right of Way (RW) Support phase, for the SHOPP Collision Severity Reduction project on Route 49, in Nevada County. (EA 3H510, PPNO 4136) This project is located on Route 49 near the City of Grass Valley, from north of La Barr Meadows Road to north of Crestview Drive, in Nevada County. The project will improve safety and add operational improvements by constructing two-way left-turn and right-turn lanes, 10-foot shoulders, a northbound slow-moving truck lane, and retaining walls. In March 2022, the project’s PS&E and RW Support phases were programmed for $2,950,000 and $1,990,000, respectively, in the SHOPP for allocation in Fiscal Year 2022-23. In June 2023, the project received a PS&E and RW Support allocation for $2,950,000 and $1,990,000 respectively. In July 2024, the project received G-12 funds in the amount of $495,000 for the PS&E and $399,000 for the RW Support phases. The PS&E and RW Support phases are currently 70 percent complete. The remaining budget is $540,000 for the PS&E and $480,000 for the RW Support phases, which is insufficient to complete the phases. The project is scheduled to be Ready to List in June 2025. If this request for additional funding is approved, it is anticipated that PS&E activities through award will be completed by November 2025. The project realized cost increases to the PS&E phase due to additional efforts with the design of retaining walls, providing information for the Resolutions of Necessities (RONs), and modifications to the plans for the approval of a RW 3W Certification. The project realized cost increases to the RW Support phase due to preparation and submittal of the RONs and RW 3W Certification. During PS&E, the Department identified the need to adjust the roadway alignment to improve sight distance for improved safety, minimize right of way impacts, and reduce capital costs. As a result, retaining walls were added to further minimize right of way impacts and reduce the number of parcel acquisitions from 47 to 40. The retaining walls required a special design by the Division of Engineering Services, and geotechnical studies. Additional support is also required for the Design unit to provide mapping, data, and information in preparation of the RONs for submittal to the Commission. The cost increase for RW Support is due to five parcels requiring the condemnation process and RONs to be prepared for submission to the Commission for approval. The first set of RONs were submitted to the Commission in December 2024, followed by one in January 2025. The remaining RONs will be submitted in May 2025.

In January 2026, it was reported that a northbound truck climbing lane is planned from just south of Grass Valley from McKnight Way to La Barr Meadows, along with a southbound truck climbing lane, a center left turn lane, shoulders, and some right turn pockets in that segment. For this project, right of way impacts will be avoided as much as possible, sometimes actually shifting the alignment of the roadway off of the current alignment more north or west or east. Contract bids were awarded for the project in the last quarter of 2025, construction should start in Spring 2026. It was also reported that Granite (NYSE:GVA) announced it has been selected for the contract valued at approximately $66 million. The project will expand Route 49 to four lanes with a center turn lane, improving safety, traffic flow, and local access. The new alignment will include: (•) Truck Climbing Lane for improved freight mobility. (•) Accessibility Enhancements to multiple driveways and side streets. (•) Drainage Improvements to support long-term roadway durability. (•) Wildlife Crossing Box Culvert to protect local ecosystems. Granite will supply 75,000 tons of HMA and RHMA from its Bradshaw Hot Plant to pave the new roadway, ensuring high-quality materials and efficient delivery.

La Barr Meadows Widening (NEV 11.11/13.3)

In 2007, the CTC recommended funding $18.568M from the Corridor Mobility Improvement Account (CMIA) for the La Barr Meadows widening. In January 2008, the CTC approved the mitigated negative declaration. This project in Nevada County will make roadway improvements that include widening from two lanes to four lanes and construction of a new interchange along a portion of Route 49 near Grass Valley. The project is fully funded in the 2006 State Transportation Improvement Program (STIP). The total estimated project cost, capital and support, is $40,500,000. The project is funded from $10,966,000 Regional Improvement Program, $10,966,000 Interregional Improvement Program, and $18,568,000 Corridor Mobility Improvement Account. It is estimated that construction will begin in Fiscal Year 2008-09. The project will involve construction activities in an area that is habitat to federally protected migratory birds. The project will also involve acquisition of new right-of-way and residential relocations.

In March 2009, the CTC adjusted the funding on this due to increased cost. Delays in acquisition of some of the right of way parcels have led to delays in the delivery of design. Some of this was due to problems with ROW acquisition. Another problem was that the need to relinquish four new frontage roads to the County was not originally anticipated, requiring added effort in processing relinquishment activities, including a cooperative agreement, relinquishment agreement, and field surveys. These changes updated the End Design date to April 1, 2009 and the Begin Construction date to July 15, 2009.

In mid-May 2011, ground was broken on this project, which was now a $29 million project. The project will widen a 1.5-mile stretch to four lanes between Little Valley Road, just north of Alta Sierra, and Cornette Drive, south of Grass Valley. The project also includes the construction of frontage roads, right-turn projects, wider shoulders and the installation of traffic signal at La Barr Meadows Road intersection with the highway. Soundwalls will be constructed at three locations. The project is planned for completion in the fall of 2012.

In March 2013, the CTC adjusted the funding again, allocating an additional $840,000 in State Transportation Improvement Program (STIP) funds. The increase is due to a new Construction General Permit (CGP) for storm water discharges, drainage system modifications, increased traffic handling and a low asphalt price index at time of contract award plus a few miscellaneous issues.

Route 49 is a currently signed freeway from approximately 1 mile south of the Route 49/Route 20 interchange near Grass Valley, and runs for a length of 5 miles until reaching the Route 49/Route 20 interchange north of Nevada City (~ NEV R14.318 to NEV 15.15). This section of freeway was built in the late 60's. There are currently studies under to plan upgrading Route 49 to 4 lanes between Auburn and Grass Valley.
