Arizona State Route 95 Truck


Arizona State Route 95 Truck is a 0.85-mile-long spur of Arizona State Route 95 located in Parker.  Arizona State Route 95 Truck follows California Avenue north of Riverside Drive to California State Route 62 at the Colorado River Bridge.  What is now Arizona State Route 95 Truck was originally a ferry crossing of the Colorado River and later part of Arizona State Route 72.  The Colorado River in Parker was bridged by a pontoon highway crossing during late 1935 with a permanent span being completed during 1937.  Arizona State Route 95 Truck was created in 1962 when the mainline highway was extended north of Parker.  The current Colorado River Bridge carrying Arizona State Route 95 Truck and California State Route 62 opened during 2014.  Featured as the blog cover is the 1937 Colorado River Bridge when it was part of Arizona State Route 72. 




Part 1; the history of Arizona State Route 95 Truck

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.   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." 

What is now Arizona State Route 95 Truck was commissioned into the Arizona State Highway System as a component of Arizona State Route 72 in the early 1930s.  Arizona State Route 72 as originally began at US Route 60 at Hope and ended at the Colorado River Ferry in Parker.  Arizona State Route 72 can be seen in detail between Hope-Parker on the 1935 State Highway Department Map of Arizona.  


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.


Parker would incorporate as a town during 1948.  During the early 1960s Arizona State Route 95 had been straightened directly north of Quartzsite.  During 1962 Arizona State Route 95 was extended and replaced Arizona State Route 172 north of Parker.  Subsequently Arizona State Route 72 was truncated to a junction with Arizona State Route 95 in the southern outskirts of Parker.  The Colorado River Bridge in Parker and California Avenue north of Riverside Drive were reassigned as Arizona State Route 95 Truck.  

1970 California Legislative Chapter 1473 extended California State Route 62 from Twentynine Palms east to the Colorado River Bridge at the Arizona state line.  The California Division of Highways assumed maintenance of the existing Aqueduct Road which connected US Route 95 at Vidal Junction to The Colorado River Bridge.  California State Route 62 can be seen terminating at the Colorado River Bridge near Parker on the 1975 Caltrans Map.  


Parker became the seat of the newly created La Paz County on January 1, 1983.  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.  


Part 2; a drive on Arizona State Route 95 Truck

From the community of Earp in San Bernardino County eastbound California State Route 62 makes a right-hand turn from Aqueduct Road towards the Colorado River Bridge. 

California State Route 62 eastbound crosses under the 1908 Arizona & California Railway Bridge to a terminus at the foot of the Colorado River Bridge.  The 1908 Arizona & California Railway Bridge partially burned during September 2019, but the structure did not fail.  The Arizona & California Railway came under the ownership of RailAmerica during 2012.  





California Avenue crosses the Colorado River Bridge and becomes Arizona State Route 95 Truck.  An Arizona State Route 95 Truck shield can be found as the highway enters Parker.  



Arizona State Route 95 Truck follows California Avenue to a terminus at mainline Arizona State Route 95 at Riverside Drive.







From northbound Arizona State Route 95 a guide sign denotes Arizona State Route 95 Truck as "To California State Route 62."

The Bayshore Freeway (US Route 101)

The Bayshore Freeway is a 56.4-mile component of US Route 101 located in the San Francisco Bay Area.  The Bayshore Freeway connects the southern extent of San Jose to the Central Freeway in the city of San Francisco.  The corridor was originally developed as the Bayshore Highway between 1923 and 1937.  The Bayshore Highway would serve briefly as mainline US Route 101 before being reassigned as US Route 101 Bypass in 1938.  Conceptually the designs for the Bayshore Freeway originated in 1940 but construction would be delayed until 1947.  The Bayshore Freeway was completed by 1962 and became mainline US Route 101 during June 1963.   Part 1; the history of the Bayshore Freeway Prior the creation of the Bayshore Highway corridor the most commonly used highway between San Jose and San Francisco was El Camino Real (alternatively known as Peninsula Highway).  The  American El Camino Real  began as an early example of a signed as an Auto Trail starting in 1906.  The era of State Highway Mainte

Former US Route 101 and California State Route 41 through Paso Robles

Paso Robles is a city located on the Salinas River of San Luis Obispo County, California.  As originally configured the surface alignments of US Route 101 and California State Route 41 converged in downtown Paso Robles.  US Route 101 originally was aligned through Paso Robles via Spring Street.  California State Route 41 entered the City of Paso Robles via Union Road and 13th Street where it intersected US Route 101 at Spring Street.  US Route 101 and California State Route 41 departed Paso Robles southbound via a multiplex which split near Templeton.   Pictured above is the cover of the September/October 1957 California Highways & Public Works which features construction of the Paso Robles Bypass.  Pictured below is the 1935 Division of Highways Map of San Luis Obispo County which depicts US Route 101 and California State Route 41 intersecting in downtown Paso Robles.   Part 1; the history of US Route 101 and California State Route 41 in Paso Robles Paso Robles ("Pass of the

Paper Highways; US Route 20 Alternate over Teton Pass

The 8,431-foot-high Teton Pass lies in the Teton Range of the Rocky Mountains within Teton County, Wyoming.  Presently Teton Pass is crossed by Wyoming Highway 22 and Idaho State Highway 33.  At one point the highway over Teton Pass was signed as US Route 20 Alternate.  US Route 20 Alternate was over Teton Pass never formally approved by the American Association of State Highway Officials nor has the corridor ever been officially part of a US Route.  The image above was taken from the 1949 Rand McNally Map of Idaho, Wyoming and Montana which shows US Route 20 Alternate branching from US Route 20/US Route 191 near Sugar City, Idaho and crossing Teton Pass towards Jackson, Wyoming.   Part 1; the history of US Route 20 Alternate over Teton Pass No major Auto Trail was ever assigned to Teton Pass as evidenced by the 1925 Rand McNally Map of Idaho, Montana and Wyoming .  On the Wyoming side Teton Pass can be seen as part of Wyoming Highway 25 ("WY 25") whereas no State Highway is
