Routing Routing

Rte 62From Route 10 near Whitewater to the Arizona state line near Earp via Morongo Valley, the vicinity of Yucca Valley, Twentynine Palms, Rice, and Vidal Junction.

Post 1964 Signage History Post 1964 Signage History

062/247As defined in 1963, Route 62 was the route from "Route 10 near White Water to Utah Trail Road in the town of Twentynine Palms via Morongo Valley and the vicinity of Yucca Valley."

In 1970, Chapter 1473 extended the route to the Arizona state line near Earp via Morongo Valley, the vicinity of Yucca Valley, Twentynine Palms, Rice, and Vidal Junction.

In 1981, Chapter 292 fixed a typographical error, changing "White Water" to "Whitewater"

This route was originally planned as freeway from Route 10 to Route 247, where it would have connected to the Old Woman Springs Freeway and continued to Route 18.

In the Initial Study and Proposed MND for the Route 62 Safety Improvements, Caltrans described the route as follows:
(Source: Route 62 Safety Improvments Initial Study and Proposed MND, April 2018)

Route 62 begins at I-10 near Whitewater and ends east of Earp at the Arizona state line. Generally, an east-west route, it parallels I-10 (I-10 is to the south). Near the state line, Route 62 joins with Arizona 95, a north-south route. Route 62 is a 4-lane divided expressway from the junction with I-10 to 0.8 mile east of the Riverside/ San Bernardino County line. From 0.8 mile east of the Riverside/San Bernardino County line to Sherwood Road immediately east of Yucca Valley, Route 62 is a four-lane divided conventional highway. From Sherwood Road to Adobe Road, in Twentynine Palms, Route 62 is a four-lane undivided conventional highway. From Adobe Road to the Arizona state line, Route 62 is a two-lane conventional highway. Route 62 traverses unincorporated portions of northern Riverside County and southern San Bernardino County. The route serves the unincorporated communities of Morongo Valley, Joshua Tree and Earp, the Town of Yucca Valley, the City of Twentynine Palms, and the United States Marine Corps Air/Ground Combat Training Center in Twentynine Palms. Route 62 is 151.9 miles in length and lies entirely within Caltrans District 8 jurisdiction.

Pre 1964 Signage History Pre 1964 Signage History

This routing was LRN 187 between US 60/US 70/US 99 (LRN 26) and Yucca Valley. This was defined in two portions: Route 10 to Morongo Valley in 1933; the remainder in 1959. It is unclear how this was signed.

The route was LRN 218 between Yucca Valley and Twentynine Palms. This was defined in 1961. The remainder of the route was defined in 1970.

Route 62 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 62 between 1934 and 1964.

Status Status

In May 2013, the CTC authorized $15,309,000 to overlay 25.6 lane miles of pavement, widen 12 lane miles of inside shoulder, overlay bridge decks with polyester concrete, reconstruct metal beam guardrail, and make drainage improvements near Desert Hot Springs, from Route 10 (~ RIV R0.0) to Indian Avenue (likely Indian Canyon Dr, which is RIV R6.451, and which accounts for 12 lane miles of inside shoulder). Project will improve safety and ride quality.

TCRP Project #129 in Yucca Valley

[062 Improvements]TCRP Project #129 will add traffic and pedestrian safety and utility undergrounding projects in the Route 62 right of way. In April 2008, the Town of Yucca Valley requested amending the project to redistribute $600,000 in TCRP funds from Construction to Environmental (PA&ED) and to update the project schedule and funding plan. By constructing safety improvements and utility undergrounding, this project will reduce the accident rate and provide safety improvements for pedestrians and motorists along Route 62 between La Honda Way (~ SBD 9.627) and Dumosa Avenue (~ SBD 12.19) in the town of Yucca Valley. Other project improvements include sidewalk construction, associated drainage, and raised medians to prevent unauthorized left turn movements. Eliminating accidents and left turns will result in reduced traffic congestion on Route 62. The Environmental (PA&ED) work began in May 2002. However, work on the project was suspended due to uncertainties with the project funding. When work resumed, it was determined that the previous traffic studies and other analysis had become outdated and would need to be updated. The project is now scheduled for construction in FY 2009/2010. The PA&ED was completed in February 2009, with $298,000 in TCRP savings. The Plans, Specification, and Estimates (PS&E) started in November 2009. The project has been under development for many years. Based upon a 2010 update to the project costs, the PS&E has increased from $240,000 to $538,000. This shortfall was covered in September 2010 by reprogramming $298,000 TCRP savings from PA&ED.

In January 2013, the CTC authorized $778,000 to the Town of Yucca Valley for Route 62 Median and Sidewalk Improvements. This project, in the town of Yucca Valley, on Route 62 from La Honda Way to Dumosa Avenue will provide sidewalks and install raised medians.

In March 2013, the CTC authorized $723,000 to the Town of Yucca Valley for Route 62 Improvements between Apache Trail (~SBD 10.823) & Palm Avenue (~ SBD 11.37). This project will construct traffic and pedestrian safety improvements.

In June 2020, the CTC amended the following project into the SHOPP: 08-SBd-62 15.3/28.9. PPNO 3016T. ProjID 0820000011. EA 1L290. On Route 62 in and near Yucca Valley and Twentynine Palms, from east of Yucca Mesa Road/La Contenta Road to Alfalfa Avenue/Sherman Road. Restripe existing two-way left-turn lanes to painted median islands and install rumble strips. PA&ED $686K; PS&E $522K; R/W Sup $26K; Con Sup $504K; R/W Cap $20K; Const Cap $1,226K; Total $2,984K. BC: 4/1/2022.

In August 2017, it was reported that Caltrans announced the completion of a project in Joshua Tree (~ SBD 18.305) that actively incorporates complete streets concepts, designed to accommodate all users. The project on Route 62 in Joshua Tree used funds from a current construction project to restripe the downtown section of Joshua Tree with bike lanes and diagonal parking in order to more safely move vehicles, pedestrians and bicyclists through the downtown business district. The majority of Route 62 is a four-lane highway with two lanes in each direction with approximately eight foot shoulders. The section of Route 62 through downtown Joshua Tree has outside shoulders that extend over forty feet—space now being used to stripe out areas to park, add bike lanes and create more controlled lanes. The striping improvements will make it easier and safer for vehicles to park, exit the highway and prevent illegal passing. It will also provide better access for bicyclists and enhance safety for all users of the downtown area.

Route 62 Widen Shoulders and Install Rumble Strips Project | 08-SBD-62 (PM 41.0/41.5 AND 60.6/61.1), 08-RIV-62 (PM 81.6/82.2)

Rte 62 Rumble StripsIn April 2018, Caltrans posted a draft Initial Study and Proposed MND regarding the Route 62 Widen Shoulders and Install Rumble Strips project. This covers three distinct segments of Route 62: 08-SBD-62 (PM 41.0/41.5 AND 60.6/61.1), and DISTRICT 08-RIV-62 (PM 81.6/82.2) [Note: Route 62 has two segments in RIV: 0.0-9.237 near Desert Hot Springs, and another segment starting at ~ RIV 79.525 (continuing numbering from SBD) and going to RIV 90.202 (and then continuing number back into SBD)]. The project proposes to widen the outside shoulder of Route 62 to eight feet in both directions and install ground-in rumble strips on the centerline and on the outside shoulders. The proposed project is located in a rural setting on Route 62 at post miles (PM) 41 to 41.5 (Segment 1) and PM 60.6 to 61.1 (Segment 2) within San Bernardino County, and from PM 81.6 to 82.2 (Segment 3) in Riverside County. The project is within the Cadiz Valley Southeast, Valley Mountain, and Clarks Pass 7.5 minute U.S. Geological Survey (USGS) topographic quadrangles. Within the project limits, Route 62 is a two-lane conventional highway that traverses unincorporated portion of southern San Bernardino County and northern Riverside County. Existing shoulder widths for the segment of the route within the project vicinities vary from zero to four feet wide. The existing shoulder widths do not meet current Caltrans Highway Design Manual Standards. The posted speed limit along these segments of Route 62 is 50 to 55 miles per hour (mph). The highway is on relatively flat terrain and is part of the Terminal Access Route to the National Network for Surface Transportation Assistance Act (STAA) trucks. The section of Route 62 experiences a higher than average incidence of cross-centerline accidents.

Pre-1964 Legislative Route Pre-1964 Legislative Route

The route that would become LRN 62 was first defined in the 1919 Third Bond Act was the route from Azuza to Pine Flats in San Gabriel Canyon. In 1933, the route was extended from Huntington Beach-Whitter Road near Buena Park to [LRN 9] near Azuza. This was codified in 1935 into the highway code as:

  1. [LRN 171] near Buena Park to [LRN 9] near Azuza
  2. [LRN 9] at Azuza to [LRN 61] via Pine Flats in San Gabriel Canyon

It was quickly amended by Chapter 626 in 1935 to split the first segment (the reason why is unclear):

  1. [LRN 171] near Buena Park to Los Angeles-Orange County Line near La Habra
  2. [LRN 26] near West Covina to [LRN 9] near Azuza
  3. [LRN 9] at Azuza to [LRN 61] via Pine Flats in San Gabriel Canyon

In 1945, Chapter 1269 reverted the 1935 change. But, it didn't last for long, as in 1949, Chapter 1467 removed the segment from [LRN 2] (US 101) to [LRN 26] (US 70), making the definition:

  1. [LRN 171] near Buena Park to [LRN 2] near La Habra
  2. [LRN 26] near West Covina to [LRN 61] via Pine Flats in San Gabriel Canyon

Then, in 1959, the gap was restored, making the definition "[LRN 171] (US 101) near Buena Park to [LRN 61] (Route 2) via San Gabrial Canyon."

This is Route 39. It was signed in 1934.
