California State Route 259; TO I-215/CA 210

While visiting San Bernardino this past week I drove the small California State Route 259 freeway.


While often called a glorified ramp the route of CA 259 is a one mile full-fledged freeway which connects Interstate 215 to California State Route 210.  Legislatively the route that became the modern CA 259 was part of Legislative Route Number 43 which was adopted into the State Highway system in 1933 according to CAhighways.org.

LRN 43 in San Bernardino originally ran from along E Street.  In 1934 the route of CA 18 added to E Street between LRN 190 on Highland Avenue south to LRN 26 on Colton Avenue which also carried US 99/70.  CA 18 can be seen on E Street in San Bernardino on this 1938 State Highway Map.

In 1960 CA 18/LRN 43 appears to have been aligned onto I Street.

The I Street alignment is made more clear on a 1961 Traffic Census.

The route number assigned during the California State Highway Renumbering of 1964 is unclear.  The route likely was remained signed as CA 18 but the new route number if any is unknown.

According to CAhighways.org CA 259 was assigned in 1965.  The route of CA 259 makes it's first appearance on the 1966 State Highway Map routed between I-15/US 66/US 395 north on I Street and east on 30th Street to CA 18/CA 206 at E Street.

On the 1970 State Highway Map CA 259 appears as a full freeway between I-15/US 66/US 395 to CA 18/CA 206.  The 1967 and 1969 State Highway Map editions do not display CA 259 at all which makes it unclear when the freeway grade was complete.

My approach to CA 259 was from the northbound Base Line Street Ramp in San Bernardino.  Ahead the interchange between I-215 and CA 259 can be seen. 


CA 259 is not given any reassurance shields and is as access to CA 210 headed northbound.   Even the reassurance shields state "To CA 210."



Northbound CA 259 Exit 1A accesses former CA 30 on Highland Avenue.  CA 259 traffic is advised the freeway provides access to CA 330.



Exit 1B on CA 259 north accesses E Street.





CA 259 terminates at CA 210 east near the exit for CA 18 at Waterman Avenue.  It should be noted that the current CA 210 freeway was once signed as CA 30.

The only way you know it's CA-259 is on the bridge overcrossing signs and on the bents.

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
