    Naming Naming

    Capt. Paul Vincent RotondaroThe portion of Route 140 between PM MER 6.5 and MER 11 in the County of Merced is named the “Paul Vincent Rotondaro Memorial Highway”. It was named in memory of Paul Vincent Rotondaro, who grew up in the City of Merced, and is an alumnus of Our Lady of Mercy School and Golden Valley High School. During his time at Golden Valley High School, Paul was an active member in the Future Farmers of America, as well as an outstanding offensive lineman for the Golden Valley Cougars football team. After graduation from high school, always seeking to expand his knowledge, Paul graduated from Merced College, where he received his Associate of Science degree in Fire Science and was actively working on his bachelor’s degree. Paul began his career of public service with CAL-FIRE as a Firefighter 1 at the Ahwahnee Fire Station in the Madera-Mariposa-Merced Unit in 2006; and excelled at CAL-FIRE, promoting to Firefighter II in the Merced Division of the Madera-Mariposa-Merced Unit in 2011 and to LT Fire Apparatus Engineer in 2012, transferring to the Riverside Unit as a permanent Fire Apparatus Engineer in 2015, and returning to Madera-Mariposa-Merced Unit in 2016 to become a Fire Captain shortly thereafter. Paul performed many aspects of the job, including as an active participant on the Type 1 Hazardous Materials team in Merced, a member of the CAL-FIRE Incident Management Team 3 in the Finance Section, a member of the Merced County Type 2 Rescue team, overseeing radio technology issues for the entire Merced County Fire Department, and serving as part of the aircraft rescue and firefighting team at Castle Airport. Paul was killed on October 2, 2019, in a head-on collision while on duty with CAL-FIRE. Named by Assembly Resolution ACR 144, Res. Chapter 131, 08/19/22.

    In 1934, Route 140 was signed along the route from Merced to Jct. Route 120 through Yosemite National Park via Mariposa. It was part of LRN 18. The segment from Merced to Mariposa was defined in 1909. From Mariposa to Yosemite National Park was defined in 1916. The portion from the old boundary of Yosemite National Park near Crane Flat to Route 120 was originally part of the route, defined in 1915, but was removed in 1943. There are points where this road has been rebuilt, and the old roadbed is still visible.

    Currently, Route 120 enters Yosemite National Park in Tuolumne County via the modern Big Oak Flat Road. Originally Route 120 entered Yosemite National Park via the Old Tioga Pass Road and Route 140 entered via the Old Big Oak Flat Road. The Big Oak Flat Road is the second oldest highway into Yosemite just behind the Old Coulterville Road. Much of the alignment of Route 120 follows the path set out by the Big Oak Flat Road. Details on the history of the entrance into Yosemite and the changes in routing may be found in the Gribblenation Blog "Old California State Route 140 and California State Route 120 entrances to Yosemite National Park".
    (Source: Gribblenation Blog "Old California State Route 140 and California State Route 120 entrances to Yosemite National Park")

    Tom Fearer (Max Rockatansky) on AAroads notes that the alignment of Tioga Pass Road used to be very different in the early days of the state highway system. Route 120 took a turn on what is now Evergreen Road to Aspen Valley Road which used to be the original routing of Tioga Pass Road. Route 140 from Evergreen Road used the modern alignment of Route 120 to Yosemite National Park. The alignments can be seen very easily on the 1935 Tuolumne County Map. Tioga Pass Road originally traversed Aspen Valley way north of the modern road where it met up with the modern alignment of the road via White Wolf Road. Sometime between 1942 and 1944, Tioga Pass Road was moved to the modern realignment which resulted to changes to Route 120 and Route 140. Route 140 was cut back to the El Portal Entrance of Yosemite on the Merced River while Route 120 was rerouted off of Evergreen Road onto Big Oak Flat Road where Route 120 enters Yosemite today. The changes are reflected on the 1954 and 1955 state highway maps.

    Route 140 east of Merced was one of the very first state highways to be commissioned (it was LRN 18) as an "all-weather" route into Yosemite. But like all roads built next to rivers to take advantage of the relatively low elevation, the trade-off is perennial flood damage.

    Bradley Overhead (~ MER 36.483 to MER 37.396)

    In October 2006, the CTC had on its agenda a resolution for approval for future consideration of funding a project on Route 140 in Merced County for which a Final Environmental Impact Report (FEIR) has been completed. The project is partially funded in the 2006 State Transportation Improvement Program (STIP) for Project Approval and Environmental Document (PA&ED) and Plans, Specifications and Estimate (PS&E) for $2,712,000 in the Regional Improvement Program (RIP). The total estimated project cost is $41,500,000 for capital and support. Construction is estimated to begin in Fiscal Year (FY) 2008-2009. The project is referred to as the "Bradley Overhead and Replacement Project", and is just E of Merced (~ MER 037.07).

    In August 2012, the CTC approved an additional $1,763,000 in funding in the city of Merced, from Marthella Avenue to Santa Fe Avenue at the Bradley Overhead (~ MER 36.483 to MER 37.396). The goal is to widen from 2 to 4 lanes with 2-way left turn lane and sidewalks. The funding should add 2.2 lane miles.

    In January 2017, the CTC relinquished right of way in the city of Merced along Route 140 on Baker Drive (10-Mer-140 PM 36.8/37.2, between Parsons and E Santa Fe), consisting of collateral facilities.

Construction of a rockfilled gabion basket wall with stone base support/buttress is the proposed repair method to repair the failed slope and stop erosion from the culvert at this site. The purpose of the project, also known as the SR-140 Slope Repair Project, is to prevent further erosion of the slope and protect the highway and the associated culvert. Caltrans is the lead agency for the preparation of the environmental document for the project pursuant to both the California Environmental Quality Act and the National Environmental Policy Act. The location is S of Briceberg, between the two Bear Creek Bridges.

    Ferguson Slide Rock Shed / Major Damage Repair (10-MPA-140 42.0/42.7)

    140 FergusonOn April 29, 2006, there was a huge landslide that covered about 300 feet of highway between Mariposa and Yosemite National Park. It is unclear if the original alignment can be repaired. On July 20, CalTrans started building a limited bypass around the slide area, and this was finished on July 31, 2006. Yosemite tourists are urged to enter the park via Route 120 from Oakdale or Route 41 from Fresno.

    In May 2014, the CTC approved for future consideration of funding a project in Mariposa County that will construct repairs or a permanent bypass on a portion of Route 140 that was blocked and damaged by the Ferguson rockslide. The project is programmed in the 2014 State Highway Operation and Protection Program. The total estimated cost is $132,550,000 for capital and support. Construction is estimated to begin in Fiscal Year 2015-16.

    In June 2015, an update was provided on the Ferguson Project. The $133 million project will restore highway access to a section of Route 140 that was damaged by the Ferguson rock slide in 2006. The two phase project will result in a two-lane 750-foot rock shed along the existing route. Caltrans started the project in March 2015, when crews removed about 63,000 tons of rock and debris. Subsequent visual inspection of the exposed slope led Caltrans to reconsider the lateral design strategy for the rock shed. The approach transitioned to a wall structure that would require Caltrans to leave the remaining rock to help facilitate geotechnical bores and ultimately construct the rock shed. As of June 2015, the structure was designed to include two 12-foot-wide lanes, two 8-foot-wide outside shoulders and a 4-foot-wide emergency walkway on the river side. Motorists are currently constrained by one-way traffic control, using a temporary bypass route. Construction of the rock shed is anticipated to begin in 2016. The two lanes on the original alignment will be reopened once the project is complete. Other alternatives considers, but ultimately not selected, included Alternative T-3, which would have constructed a tunnel on a new alignment, tunneling into the west canyon wall, under the rockslide, and realigning with the existing highway, and the no-build alternative.

    Caltrans News in December 2020 provided an update on the project. The Ferguson Project, as it is known, is the largest public works project in tiny Mariposa County’s history, likely rivaled only by the building of Route 140 itself in the early 1920s – 1922 being the date stamped on most of the historic bridges along the route. The history of the project includes a couple of massive slides at the famously unstable slope in the Wild and Scenic Merced River canyon. During the darkness sometime in the early morning hours on a December morning in 2006, a small shift of the earth caused a massive rockfall burying Route 140 in Mariposa County under 800,000 cubic yards of rock,  enough to fill nearly 44,500 full-sized dump trucks. Work had been proceeding on the project when, in November 2015, there was another massive slide. The slope was reexamined. Once it was determined that a rock shed was still viable for a project, it became clear immediately that the original plan for traditional “cast-in-place” construction was no longer viable. Caltrans designers from District 10 and Central Region (including Grant Schuster and Caroline Reyes), developed an innovative solution to construct a 750-foot, segmentally constructed launched rock shed structure on the same alignment that will be built outside of the rock fall zone and then launched into place. The installed segments will provide shelter for workers so that the entire process takes place under the protective cover of the structure as each segment is moved into place. Project alternatives considered along the way included exploring options to bore a tunnel through the mountain, build a bridge around it, or building a protective rock shed over the roadway. Building the rock shed was determined to the best solution as it maintained the existing road alignment, resulting in less land disturbance and helping protect such creatures as the threatened limestone salamander. The new design dramatically increases protection for workers and will help protect the project schedule and budget. During the Summer of 2020, the Ferguson Slide’s rock fragments, otherwise known as talus, were re-attacked. Crews "trimmed" loose rocks from the slope, basically knocking down overhanging rocks and other unstable areas. In Summer 2021, the bulk of the road-blocking talus will be removed. During those talus-removal operations, Caltrans engineers keeps a close eye on safety and is prepared to employ remote-controlled machinery when needed. Construction of the rock shed, which is still in the design phase, is scheduled for summer 2022. Although funding for the estimated $238 million project has not yet been fully secured, the plan is to proceed on that timetable. The rock shed has been deemed the safest and fastest way to re-open that long-buried stretch of Route 140.

    In March 2021, it was reported that Caltrans was preparing to perform work at the site of the Ferguson Rock Shed project on Route 140 in Mariposa County. In the first phase of an ambitious rock shed construction project, workers will remove overhanging boulders and rubble from the slope where a rock slide blocked the roadway. Crews are scheduled to conduct this work during daytime hours beginning in April 2021 and continuing into the winter season of 2021. Construction of the rock shed is scheduled to begin the summer of 2022. In May 2021, Caltrans announced the District 10 Ferguson Rock Shed Project web page that has details about the project, as well as photos, and a link to a live web cam positioned across the work site. There is also a Road2Yosemite140 Facebook page that provides updates, photos, videos and much more.

    In June 2021, the CTC approved a request for an additional $5,040,000 in Capital Outlay Support (COS), for the SHOPP Major Damage (Permanent Restoration) project on Route 140 (10-MPA-140 42.0/42.7), in Mariposa County, to complete the Plans, Specifications, and Estimate (PS&E) project phase. The SHOPP Major Damage (Permanent Restoration) project is located on Route 140, in/near the Town of El Portal, in Mariposa County.  Route 140 is an important all-weather transportation link for Yosemite National Park.  This project is also known as the Ferguson Slide Rock Shed Construction (PPNO 10-0280; ProjID 1014000148; EA 0P921), and the project proposes to construct a rock avalanche shed.  This project was initially programmed in 2012 SHOPP.  The first phase of the construction project was awarded in 2015.  In November 2015, another rockfall occurred at the site causing the project team to reconsider the project scope and strategy. As a result, additional studies were needed and the funding for the remainder of the project was de-programmed.  As further geotechnical studies were completed, the project was reprogrammed for delivery in fiscal year 2021-22 for $175 millions in construction capital. The PS&E phase was allocated in August 2017 for $5,500,000, and with the available G-12 authority of $750,000, the total phase budget was $6,250,000.  Currently, the PS&E phase is 60 percent complete, and the total remaining phase budget is $732,000.  The available budget is insufficient to complete the phase.
    (Source: June 2021 CTC Agenda, Agenda Item 2.5e.(3))

    Cost increase rationale: The Route 140 Ferguson Slide is one of six projects procured by the Department under the Construction Manager/General Contractor (CMGC) pilot program authorized by Assembly Bill No. 2498. During the PS&E of this project, the design of the rock shed significantly changed. Further, to accommodate the new field conditions related to the slide event in 2015, talus removal operations were implemented to prepare the site for the “cast in place” rock shed. However, the team decided to use a new construction method requiring less exposure to the slide, in lieu of the “cast in place” method. In 2018, PS&E was allocated for $5.5 million to get the project started with redesigning the rock shed. The $5.5 million for support cost was an estimated amount that was based on historical data for a “cast in place” rock shed design, since the scope of work had not been defined. The new design required significant effort between the Construction Manager (CM) and the Department to evaluate multiple structure types and develop a constructible method.  The Department looked into an accelerated schedule to begin construction of the rock shed in 2022. This would require new task orders for geotechnical studies/recommendations, peer review, and structure design check. In 2020, $2.85 million of the $5.5 million PS&E allocation was used to amend the CMGC contract for preliminary engineering services. These funds allowed the CM to partner with subcontractors specializing in geology and moving heavy structures for input during the design process. It also provides some advance rock shed work using the preconstruction services contract. A design of this complexity requires many staff working on the project full time to meet delivery in 2022. There are multiple task orders for geotechnical studies, structure design check, and structures peer review, and design of the rock shed needs to be further developed into a complete PS&E package. Environmental can finalize the Wild and Scenic Route Determination and secure any necessary permits.
    (Source: June 2021 CTC Agenda, Agenda Item 2.5e.(3))

    The discussion in the agenda item also notes that if the additional funds are not approved, the Department will not be able to complete the design of this project and plans will remain at 60 percent. The $22.7 million for construction capital has already been allocated for the Phase 1 talus removal. The talus removal is anticipated to be completed by Fall 2021 at which time the site would be ready for the rock shed construction. If PS&E for the rock shed design is not complete, potential slides could occur which would require another talus removal contract. As of 2021, this all-weather route has been closed for 15 years resulting in impacts to motorists, local economy, and goods movement. Additionally, the temporary bridges currently located at the site are nearing the end of their service life.

    In August 2021, it was reported that Caltrans has completed the process of dislodging overhanging rocks at the site of the Ferguson rock slide and will begin removing more than 100,000 tons of rocks as it continues the Ferguson Rock Shed project on Route 140 in the Merced River Canyon. Approximately 20 trucks, each with 20 tons of capacity, will remove as many as 80 total loads from the site per day.  The work is scheduled to occur during daytime hours Monday through Friday from August until November 2021.More than 140,000 tons of rocks (talus) will be cleared, making way for workers to construct a 675-foot long shed that will protect motorists from future slides and restore full access for the community of El Portal and visitors to Yosemite National Park on Route 140 in Mariposa County. Travelers can access El Portal and Yosemite National Park on Route 140 via the existing temporary vehicle bridges over the Merced River or take Route 120 into the park. Construction of the shed is scheduled to begin in spring 2022 and is anticipated to continue through 2027.

    Naming Naming

    Special Agent Richard (Rick) K. Oules Memorial HighwayThe portion of Route 140 from Arboleda Drive to Plainsburg Road in the County of Merced (~ MER 40.788 to MER 43.71) is named the "Special Agent Richard “Rick” K. Oules Memorial Highway". It was named in memory of Special Agent Richard “Rick” K. Oules, who was born in 1956 in Merced, California. Special Agent Oules received his Bachelor of Arts Degree in management from Saint Mary’s College in Moraga, California. Special Agent Oules began his law enforcement career in 1977, with the Merced County Sheriff’s Department, where he served as a Patrol Deputy, Narcotics Detective, and Patrol Sergeant. In 1987, he joined the Department of Justice as a Special Agent and was assigned to the Bureau of Narcotic Enforcement, where he worked on and supervised a clandestine lab enforcement team resulting in the investigation and dismantling of approximately 300 methamphetamine laboratories. In 2005, he was appointed as the Director of the Department of Justice’s Division of Law Enforcement, where he oversaw one of the largest state investigative law enforcement agencies in the United States. Special Agent Oules retired from the department in 2008 and, after a short break, joined the United States Attorney’s Office in Sacramento, as a Law Enforcement Coordinator, where he served until his death. Special Agent Oules was recognized for his many achievements by being awarded the California Coalition of Law Enforcement Associations’ Top Manager Award for Excellence in Law Enforcement Leadership. Special Agent Oules was the past President of the California Narcotic Officers’ Association (CNOA), served on the CNOA Executive Board of Directors and the Executive Board of Directors of the California Peace Officers’ Association, and was appointed to the California Council on Criminal Justice. On April 4, 2011, Special Agent Oules died at 55 years of age after a courageous battle with lung cancer, which was determined to be a result of his frequent long-term exposure to the large number of chemicals and solvents found in methamphetamine laboratories. Named by Senate Concurrent Resolution 77, Res. Chapter 75, on June 26, 2014.

    Between the Merced county line near Planada and Yosemite National Park (~ MER 50.301/MPA 0.000 to MPA 50.32), this segment is named the Central Yosemite Highway. It was named by Assembly Concurrent Resolution 27, Chapter 69, in 1989.

    Braden VarneyThe five-mile portion of Route 140 north of its intersection with Route 49 (MPA 18.511 to MPA 23.511) is named the CAL FIRE Firefighter Braden Varney Memorial Highway. Name in memory of Department of Forestry and Fire Protection (CAL FIRE) Heavy Fire Equipment Operator Braden Varney, who passed away in the line of duty on July 14, 2018, at 36 years of age, while battling the Ferguson Fire in Mariposa County, California. Braden Varney was born in Mariposa County in May 1982, and was raised there. Varney was a 10-year veteran of the Department of Forestry and Fire Protection, having followed in the footsteps of his late father, Gordie Varney, another department heavy fire equipment operator who also perished in the line of duty. Throughout Braden’s life, he generously donated thousands of dollars worth of time and equipment to build and maintain the road to the Barrier-Sweetwater Youth Camp in Mariposa County. Braden and his father simply loved Sam Hensley’s vision and wanted to support “getting the kids to camp”. On July 14, 2018, Braden was operating his bulldozer on the Ferguson Fire in Mariposa County and, during the early morning hours, his bulldozer experienced a rollover that resulted in Braden’s passing. It was named by ACR 47, Res. Chapter 108, Statutes of 2019, on 07/08/19.

    Named Structures Named Structures

    Agua Fria Historical PlaqueThere is a historical monument and plaque dedicated to the community of Agua Fria placed within the right-of-way of Route 140, in Mariposa County, at a site that is located near the junction of State Highway Route 140 and Agua Fria Road (~ MPA 16.592). Agua Fria was the first county seat of Mariposa County. The monument and plaque was placed by the Matuca Chapter of the Ancient and Honorable Order of E Clampus Vitus. Authorized by Assembly Concurrent Resolution 140, Chapter 96, July 12, 2000. The plaque reads: "Agua Fria. Discovered by Sonoran miners in the early summer of 1849. It was located about a quarter mile above the two springs of cold water from which the town derived its name. Agua Fria was the first county seat from Feb. 18, 1850 to Nov. 10, 1851. During this time the town consisted of about a dozen stores, three card monte, faro tables, a billiard room, hotel and bowling alley. The town of Agua Fria soon declined, when in 1852 the town of Mariposa became the seat of government. On June 22, 1866 a fire broke out which destroyed the entire town and it was never rebuilt. Dedicated by Matuca Chapter 1849, E Clampus Vitus, April 1, 2000 (6005), Credo Quia Absurdum"

Statistics Statistics

Overall statistics for Route 140:

Pre-1964 Legislative Route Pre-1964 Legislative Route

In 1933, Chapter 767 added the routes from "Taft to [LRN 4] near Greenfield" and "[LRN 4] S of Bakersfield to [LRN 58] via Arvin" to the highway system. In 1935, this was captured in the definition of LRN 140 in the highway code, which was:

  1. Taft to [LRN 4] near Greenfield
  2. [LRN 4] south of Bakersfield to [LRN 58] via Arvin

In 1959, Chapter 1062 changed (b) to eliminate the specific routing (i.e., "…to [LRN 58] via Arvin").

It was signed as follows:

  1. From Taft to Route 99 near Greenfield.

    This segment as originally signed as US 399; it is present-day Route 119.

  2. From Route 99 south of Bakersfield to Route 58.

    This segment appears to have been unsigned before 1963. It is present-day Route 223.
