This was LRN 25, defined in 1933. It was not signed before 1963.
Route 174 was not defined as part of the initial state signage of routes in 1934. It is unclear what (if any) route was signed as Route 174 between 1934 and 1964.
Maple Way/You Bet Road Improvement (03-Nev-174, PM 2.7/4.6)
In September 2016, Caltrans published an Initial Study
and Mitigated Negative Declaration regarding this project. The project
proposes to improve safety along Route 174 in Nevada County from Maple Way
to You Bet Road, post mile 2.74 to 4.63 by realigning and widening the
highway and providing a clear recovery zone. The project is located
approximately 5.7 miles southeast of Grass Valley. Caltrans notes that
this 1.9 mile segment of roadway experienced a total of 30 collisions
during the three year period from April 1, 2010 to March 31, 2013, and
that the observed total accident rate is almost 1.65 times higher than the
statewide average for a similar type facility and the observed fatal
accident rate is 7 times higher than the statewide average for a similar
type facility. They state that the proposed project will increase curve
radii, widen shoulders, and improve the clear recovery area. This will
provide several benefits to traveler safety. First and foremost, the
increased curve radii will reduce the potential for a vehicle to lose
control. The wider shoulders will not only provide more room for
pedestrians and bicycles to travel the corridor, but they also provide
room for an errant vehicle to regain control without leaving the roadway.
The removal of fixed objects such as trees and embankments from the clear
recovery area will reduce the severity of a run off road collision.
Lastly, the improved curve radii, wider shoulders, and removal of fixed
objects along with roadway will improve sight distances for roadway users,
which will allow more time to identify and react to potential hazards
along the highway. They only presented a single build alternative and a

In December 2016, the CTC approved for future consideration of funding a project that will realign the roadway, widen shoulders, and add a recovery zone on Route 174 near the city of Grass Valley (03-Nev-174, PM 2.7/4.6). The project is programmed in the 2016 State Highway Operation and Protection Program. The total programmed amount is $28,456,000 for capital and support. Construction is estimated to begin in Fiscal Year 2017-18. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2016 State Highway Operation and Protection Program.
In May 2017, it was reported that Caltrans had started
to hold public meetings to present information for a project that proposes
to improve safety along Route 174 in Nevada County from Maple Way to Your
Bet Road. the project would include realigning curves, widening shoulders,
adding a left-turn lane at Greenhorn Access Road and improving the Clear
Recovery Zone (CRZ) on Route 174 from post mile 2.7 to post mile 4.6 in
Nevada County. This project proposed to help reduce the number and
severity of collisions within this segment of Route 174. This project is
scheduled to go to construction during the summer of 2019.

In June 2017, it was reported that Caltrans has
completed initial environmental review and design processes for road
improvements along the two miles of Route 174 between Maple Way and You
Bet Road, which were revised after public input was provided at open house
events in May 2015 and June 2016, and it plans to begin the process of
acquiring any parcels or portions of parcels that will be impacted by the
project this summer. Those improvements include realigning several curves
and widening lanes— which currently range from 11 to 11.3 feet wide
— to the state standard of 12 feet wide. Caltrans also plans to
widen shoulders — which currently range from one inch to five and a
half feet — to 8 feet, and add 20 feet of "clear recovery zone"
beyond the lane on each side of the highway, which includes the eight foot
shoulder and an additional 12 feet of area clear of any trees, poles, or
other obstructions. Currently, Caltrans has identified 49 parcels that
will be impacted, and will send out letters to the owners of those
properties notifying them of the impact within the next few months.
Construction is slated to begin during the summer of 2019 and be completed
by the fall of 2020.

The following project was included in the final adopted 2018 SHOPP in March 2018: PPNO 4451. 03-Nevada-174 2.7/4.7. Route 174 Near Rollins Lake, from Maple Way to You Bet Road. Realign roadway curves. Begin Con: 7/1/2019. Total Project Cost: $28,803K.
In January 2019, there was a briefing at the CTC
meeting from the Save Highway 174 group. The briefing was not included in the CTC minutes, but according to
their website, the group "consists of affected property owners, residents
and citizens of Nevada County who support reasonable safety improvements,
but are concerned with the current design standard for the widening and
realignment project proposed by Caltrans for a 1.9 mile portion of Route 174." A briefing on the site to the NCTC in September 2017 notes that the
concern is over a 1.9mi segment of Route 174 from Maple Way to You Bet
Road. It notes the highway will be leveled, straightened, and widened --
doubling to a minimum width of 64', including a 20' clear recovery zone.
There would be additional right of way required approx. 120' to 150', and
additional clearing to relocate electrical wires. There would be a total
acquisition of over 14 acres from 53 parcels, and removal of over 1,700
conifers, oaks, and smaller trees. Their goals are to create a highway
design standard and right-of-way width that is significantly less in scope
but still preserves safety. In July 2017, the Nevada County Board of
Supervisors wrote a letter to Caltrans, District 3 Director, requesting
that Caltrans "reassess this project and its scope of work" and to
"increase public outreach for input on the project and its design". They
appear to have a large number of concerns about the EIR, believing it should not have been a mitigated EIR.

In July 2020, it was reported that Caltrans was
starting construction on Aug. 3 on a $27.1 million safety improvement
project on Route 174 between Maple Way and You Bet Road in Nevada County.
The project is realigning several curves, widening shoulders, adding a
southbound left turn pocket at Greenhorn Access Road and improving the
clear recovery zone, allowing errant vehicles to regain control. The
project also upgrades pedestrian and bicycle facilities along a beautiful
stretch of Sierra-area highway, continuing our commitment to multi-modal
methods of transportation. DeSilva Gates Construction of Sacramento is the
primary contractor for the project. Scheduled construction work for the
2020 season includes preparation for AT&T utility relocation, drainage
improvements, tree removal, and roadway widening at various locations.
This anticipated work will prepare the roadway for core project
improvements planned for the 2021 construction season.

This route is named the "Officer Bill C. Bean Jr. Memorial Highway". Officer Bean
was a Sacramento Police officer who died on February 9, 1999 in the line
of duty during a traffic stop in the Del Paso Heights of North Sacramento.
Bean graduated from Colfax High School in 1989 where he later coached
football. He started his career in law enforcement at the Placer County
Sheriff's Department in May 1991 and later joined the Sacramento Police
Department in April 1995. Officer Bean had served with the Sacramento
Police Department for eight years at the time of his death. Bean was shot
and killed as he and his partner attempted to stop a man wanted on an
outstanding warrant. The suspect vehicle pulled over and started to drive
again, leading the officers on a low-speed pursuit. The vehicle stopped
after becoming disabled in the area of Knightlinger Street and South
Avenue. As Officer Bean exited the patrol car and attempted to talk to the
subject, the man opened fire, striking him several times. Bean had been
wearing “body armor” but a bullet entered through an arm hole
and hit him behind his left shoulder. Officer Bean's partner returned fire
but did not strike the suspect, who was captured several hours later after
a manhunt. The man was convicted of Officer Bean's murder and was
subsequently sentenced to life in prison without parole on December 18th,
2003. Named by Assembly Concurrent Resolution 68, Chapter 110, on
September 14, 1999.

There is a business routing through the town of Colfax. It uses Auburn St., Grass Valley St., and Main St. The routing separates from Route 174 just north of the I-80 junction and rejoins the highway north of town.
[SHC 263.7] From the Bear River to the Grass Valley city limits.
Overall statistics for Route 174:
In 1933, the routes from "[LRN 60] via Manchester Avenue to [LRN 2] near Miraflores" and "[LRN 2] near Orange County Hospital to Main Street, Santa Ana via Santa Ana Boulevard" were added to the state highway system. In 1935, these routes were added to the highway code as LRN 174:
In 1957, Chapter 36 deleted segment (b), and changed the origin of (a) to
"[LRN 60] west of Inglewood
via Manchester Avenue
to [LRN 2] near Miraflores". Segment (b) ran from what is now the Western Medical Center, Santa Ana to Santa Ana and
Main, and appears to have been obviated by other routes in the area.
Later in 1957, Chapter 1911 clarified the terminus: "… to [LRN 2] near Santa Ana".
The routing, as of 1963, ran from Route 1 W of Inglewood to US 101 near Santa Ana. This is (former) Route 42 (which itself is former Route 10), and corresponds to the present-day I-105. It ran along Manchester Avenue and Firestone Avenue. LRN 174 also included portions of US 101 between the junction with Route 42 and the junction with surface US 101 (LRN 2). Miraflores is approximately where Main Street meets N. Park Blvd in Santa Ana. As the freeway portion of the route was completed, this was also treated as LRN 2.
This was actually a significant route in its day, prompting numerous articles in California Highways and Public Works.
