California State Route 62



California State Route 62 is a 151-mile State Highway located in Riverside County and San Bernardino County.  California State Route 62 begins at Interstate 10 near San Gorgonio Pass and the western flank of the Sonoran Desert near Whiteriver.  California State Route 62 ascends Morongo Canyon and crosses through the Mojave Desert to an eastern terminus at the Colorado River Bridge at the Arizona state line in Parker.  California State Route 62 was initially defined during 1964 with a terminus in Twentynine Palms.  California State Route 62 was extended to the Arizona state line during 1970.  





Part 1; the history of California State Route 62

Modern California State Route 62 has an eastern terminus at the Colorado River at Parker, Arizona.  In 1908 Parker was established in what was then Yuma County as a siding of the Arizona & California Railway.  Parker was named in honor of Ely S. Parker who had been Commissioner of Indian Affairs under the Presidency of Ulysses Grant.  The Arizona & California Railway was originally a short line subdivision of the Atchison, Topeka & Santa Railway (ATSF).   The Arizona & California Railway originated in Cadiz, California and ended at Matthie siding near Wickenburg.  The Arizona & California Railway crossed the Colorado River via a truss span which still stands in Parker.  

Originally no highway service existed from Parker over the Colorado River into California.  This changed during May 1915 when ferry service was established in Parker via a paddle-wheel ship known as the "Iola." 

The first segment of road now comprising California State Route 62 entered the State Highway System via 1933 Legislative Chapter 767.  Legislative Chapter 767 defined Legislative Route Number 187 (LRN 187).  The fifth segment of LRN 187 was defined as "Whitewater to Morongo Valley.  

The Whitewater-Morongo Valley segment of LRN 187 appears for the first time on the 1934 Division of Highways Map



Much of what is now California State Route 62 east of California State Route 177 was built by the Metropolitan Water District of Southern California as the Colorado River Aqueduct Road.  Construction of the Colorado River Aqueduct began during January 1933 near Thousand Palms and was made functional on January 7, 1939.  The Colorado River Aqueduct Road (Aqueduct Road) was constructed from Parker Dam west towards modern day California State Route 62 in San Gorgonio Pass.  Modern California State Route 177 and Dillon Road are also segments of road that was originally built as Aqueduct Road.  

The Whiteriver-Morongo Valley segment of LRN 187 appears in detail on the 1935 Division of Highways Maps of Riverside County and San Bernardino County.  LRN 187 can be seen ending in Morongo Valley with a major San Bernardino County highway continuing to Twentynine Palms.  A minor road east from Twentynine Palms is displayed ending at New Dale.  



The Aqueduct Road can be seen branching east from modern California State Route 177 to the Colorado River at the Arizona state line on the 1935 Division of Highways Map of San Bernardino County.  


During December 1935 a pontoon bridge crossing the Colorado River in Parker was erected.  This pontoon structure was made possible due to the upstream Hoover Dam slowing the currents of the Colorado River.  The Colorado River Pontoon Bridge was located at the western terminus of Arizona State Route 72.  The Colorado River Pontoon Bridge can be seen from Parker in a University of California hosted photo.  


The pontoon bridge at the Colorado River was intended to be a temporary crossing until a permanent structure could be built.  The October 1937 Arizona Highways features the completed Colorado River Bridge in Parker.  The article stub notes the Colorado River Bridge to be located at the western terminus of Arizona State Route 72.  The Colorado River Bridge was constructed with funds via State appropriations and from the Bureau of Public Roads.  The paved highway on the California side of the Colorado River in San Bernardino County was constructed by the Metropolitan Water District of Southern California as part of the Colorado River Aqueduct project.  




The completed Colorado River Bridge in Parker can be seen on the 1938 Sinclair Map of Arizona.


The July/August 1954 California Highways & Public Works features the newly channelized junction of US Route 99-60-70/LRN 26 and LRN 187 near Whiteriver.  


A highway spanning east from Utah Trail Road in Twentynine Palms towards the Aqueduct Road between Desert Center and Rice can be seen on the 1956 Gousha Map of California.  This connecting road east of Twentynine Palms appears to have been constructed by San Bernardino County during the 1950s. 


The November/December 1956 California Highways & Public Works noted LRN 187 from US Route 99-60-70 to Morongo Valley was to be regraded and widened during the 1957-58 Fiscal Year.  


The November/December 1958 California Highways & Public Works announced LRN 187 from US Route 99-60-70 to Morongo Valley had an adopted freeway corridor which was selected by the California Highway Commission the previous June.  


Legislative Chapter 1062 extended Legislative Route Number 187 (LRN 187) from Morongo Valley to Lucerne Valley.  The Morongo Valley-Lucerne Valley segment of LRN 187 was initially defined as part of the Freeways & Expressways System.  The Morongo Valley-Lucerne Valley segment of LRN 187 appears for the first time on the 1960 Division of Highways Map as a planned State Highway.  



The September/October 1961 California Highways & Public Works announced the Twentynine Palms Highway from East Road in Morongo to Utah Trail in Twentynine Palms was adopted by the legislature as part of the Freeway & Expressway System.  The new segment of highway from Yucca Valley to Utah Trail was defined as LRN 218.  


LRN 218 first appears on the 1962 Division of Highways Map.  



The November/December 1962 California Highways & Public Works announced 7 miles expressway expansion of LRN 187 from US Route 99-60-70 towards Morongo Valley was budgeted for the 1963-64 Fiscal Year.  


As part of the 1964 State Highway Renumbering the Legislative Route Numbers were dropped in favor of Sign Route designations.  California State Route 62 was initially defined as "Route 10 near White Water to Utah Trail Road in the town of Twentynine Palms via Morongo Valley and the vicinity of Yucca Valley."  California State Route 62 appears for the first time on the 1964 Division of Highways Map.  



The March/April 1964 California Highways & Public Works featured completion of the Morongo Canyon Freeway segment of California State Route 62.  LRN 187 within in Morongo Canyon is noted to have been originally constructed during the 1870s after the Christiansen family settled in the area.  Early LRN 187 used the Christiansen Road until it was destroyed by floods during 1938.  LRN 187 was rebuilt at a new location in Morongo Canyon flowing the floods of 1938.  Work began to reconstruct the highway in Morongo Canyon to limited access standards on during January 1963 and was completed by the following August.  




The November/December 1964 California Highways & Public Works announced California State Route 62 between Morongo Valley and Yucca Valley was to be widened to four lanes during the 1965-66 Fiscal Year.  


The November/December 1966 California Highways & Public Works announced California State Route 62 was to be widened to four lanes from Twentynine Palms 4 miles westward during the 1967-68 Fiscal Year.  


1970 Legislative Chapter 1473 extended California State Route 62 from Twentynine Palms east to the Arizona state line near Earp and Parker.  The extended California State Route 62 first appears on the 1975 Caltrans Map.  


1981 Legislative Chapter 291 corrected the error of "White River" to "Whiteriver" in the Legislative description of California State Route 62.  

On April 12, 2010, the Metropolitan Water District received an application from Caltrans and the Arizona Department of Transportation to replace the Colorado River Bridge.  The stream under the Colorado River Bridge is noted to have dropped twenty feet which led to the loss of lateral support and embedment in the structure pilings.  


The current Colorado River Bridge opened during 2014 and was dedicated on October 1st of said year.  The current Colorado River Bridge can be seen in a YouTube video by BigRiver Drone.  The 1937 Colorado River Bridge was demolished following the opening of the current span.

California State Route 62 eastbound begins to run alongside the tracks of the Arizona & California Railway.  California State Route 62 eastbound enters the ghost town of Rice at approximately Postmile SBD 107.236.  









Rice began life as a siding of the California Southern Railroad which was incorporated in 1914.  The California Southern Railroad began at the ATSF tracks at Rice which was originally known as Blythe Junction.  The California Southern Railroad traversed southeast 42.2 miles through the Big Maria Mountains and Little Maria Mountains to Blythe in the Sonoran Desert of Riverside County.  The California Southern Railroad was completed by 1916 and was extended about another 7 miles to Ripley in 1920.  The ATSF began to lease the California Southern Railroad in 1921 and purchased it during 1942.

Rice was a rather unremarkable rail siding until World War II and the creation of the Rice Army Airfield in 1942.  The Rice Army Airfield was part of the Desert Training Center run by Major General George S. Patton which is best known today as a significant tank training ground during World War II.  Rice apparently had several thousand enlisted personnel living in the town during the war years when the Army Airfield was operating.  Supposedly the Rice Army Airfield was one of the three locations in the running for the Trinity Test which was the first detonation of a nuclear weapon.  According to conjecture/rumor the Rice Army Field was not selected to slight Patton and was moved to White Sands in New Mexico instead.

Rice was largely depopulated after World War II.  The Army Airfield was turned over to civilian use but was abandoned sometime in the 1950s.  The ruins of the gas station in Rice opened in the 1970s.  The ATSF sold the rights to the line between Rice and Ripley to the Arizona & California Railway in 1991.  Rice was largely known in modern times for a shoe tree that burned in 2003 only to be replaced by a shoe fence which still exists to this day.  The last train to run from Rice to Ripley was in December of 2007.  In 2009 all but the first four miles of rials south out of Rice were abandoned and were removed in 2011.  Aside from building foundations there isn't much left to indicate anything significant ever happened in Rice or the roll it played during World War II.

Made the drive between the Blythe Airport and Needles Airport many times. I was a weather observer that worked both sites before they were automated. Late 1980s and early 1990s. Very desolate drive, lots of dips that is for sure!

We must have crossed paths. I too worked at FCWOS EED and BLH along with PRC. Made the triangle trip many times.

Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

In the nearly 60 years Interstate 40 has been open to traffic through the Pigeon River Gorge in the mountains of Western North Carolina, it has been troubled by frequent rockslides and damaging flooding, which has seen the over 30-mile stretch through North Carolina and Tennessee closed for months at a time. Most recently, excessive rainfall from Hurricane Helene in September 2024 saw sections of Interstate 40 wash away into a raging Pigeon River. While the physical troubles of Interstate 40 are well known, how I-40 came to be through the area is a tale of its own. Interstate 40 West through Haywood County near mile marker 10. I-40's route through the Pigeon River Gorge dates to local political squabbles in the 1940s and a state highway law written in 1921. A small note appeared in the July 28, 1945, Asheville Times. It read that the North Carolina State Highway Commission had authorized a feasibility study of a "...water-level road down [the] Pigeon River to the Tennessee l...

Ghost Town Tuesday; Mannfield, FL and the stairway to Hell

Back in 2015 I went searching the Lecanto Sand Hills for the original Citrus County Seat known as Mannfield.  Unlike Centrailia in Hernando County and Fivay in Pasco County I did find something worth seeing. Mannfield is located in the Lecanto Sand Hill section of Withlacoochee State Forest somewhat east of the intersection of Citrus County Route 491 and Mansfield Road. Mannfield was named after Austin Mann and founded in Hernando County in 1884 before Citrus County Split away.  In 1887 Citrus County was split from northern Hernando County while Pasco County was spun off to the south.  Mannfield was selected as the new Citrus County seat due to it being near the county geographic center.  Reportedly Mannfield had as many as 250 people when it was the County Seat.  The town included various businesses one might include at the time, even a sawmill which was common for the area.  In 1891 Citrus County voted to move it's seat to Inverness which set the s...

The mystery of Hawaii Route 144 and temporary Hawaii Route 11

The 1959 Gousha Road map of Hawaii features two largely unknown references in the form of Hawaii Route 144 and Temporary Hawaii Route 11.  Both corridors are shown running from the boundary of Hawaii Volcanoes National Park east to Glenwood via Volcano Village.  At the time Hawaii Route 11 was using the so-called "Volcano Road" which was constructed as a modernization of Mamalahoa Highway during 1927-1928.  This blog will examine the two map references and will attempt to determine what they might indicate.  The mystery of Hawaii Route 144 and Temporary Hawaii Route 11 Hawaii Route 11 is part of Mamalahoa Highway (the Hawaii Belt Road) and is the longest Hawaiian State Route at 121.97 miles.  The highway begins at the mutual junction of Hawaii Route 19 and Hawaii Route 190 in Kailua-Kona.  From Kailua-Kona the routing of Hawaii Route 11 crosses the volcanic landscapes of southern side of the Big Island.  Hawaii Route 11 terminates at Hawaii Route 19/Ka...
