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.

Where the hell is Hill Valley? (US Route 8 south/US Route 395 east)

Recently I made a visit to Universal Studios near Los Angeles.  While on the back lot tour I came across a piece of infamous movie-borne fictional highway infamy; the location of town square of Hill Valley, California on US Route 8/US Route 395.


The above photo is part of the intro scene to the first Back-to-the-Future movie which was set in 1985. To anyone who follows roadways the signage error of US 8 meeting US 395 in California is an immediately notable error.  For one; US 8 doesn't even exist anywhere near California with present alignment being signed as an east/west highway between Norway, Michigan and Forest Lake, Minnesota.  To make matters worse US 8 is signed as a southbound route and US 395 (a north/south highway) is signed as an eastbound route.  At minimum the cut-out US 8 and US 395 shields somewhat resemble what Caltrans used in the 1980s.

Assuming Hill Valley is located on what would have been US 395 by 1985 what locales would be a viable real world analog?  US 39…

The Arroyo Seco Parkway and early terminus points of US Route 66 in Los Angeles

This past month I visited the original terminus of US Route 66 on Broadway in downtown Los Angeles and drove the entirety of the Arroyo Seco Parkway to Pasadena.


The Arroyo Seco Parkway is a 8.162 mile section of freeway which traverses from the Four-Level Interchange in downtown Los Angeles north/northeast following the Arroyo Seco to Pasadena.  The Arroyo Seco Parkway is currently designated as part of California State Route 110 but is more widely known as being a classic component of US Route 66.  While US 66 used the entirety of the Arroyo Seco Parkway the freeway also carried US 6, US 99 and CA 11 at different points throughout it's long history.  The Arroyo Seco Parkway is the oldest freeway in the western United States and depending on the definition used it can be considered the oldest in the United States.

Before the Arroyo Seco Parkway travel between Pasadena and Los Angeles on US 66 was routed on surface roads that largely avoided the Arroyo Seco.  Prior to 1933 the Dep…

"Governor Hunt Cuts Ribbon on Doomsday" - The drawnout legal battle to build the I-95 Fayetteville Bypass

It is Monday, December 15, 1980.  North Carolina Governor Jim Hunt and many other dignitaries take part in a ribbon cutting ceremony opening a new 17 mile stretch of Interstate 95 in Cumberland County.  The new road bypasses Fayetteville to the east and completes Interstate 95 in North Carolina - closing a significant gap in what many consider the backbone highway of the East Coast.  The new road moved Interstate traffic from an at-grade, four lane US 301 lined with numerous motels and restaurants onto a fully controlled and traffic light-free limited access freeway. 

Meanwhile at a Quality Inn along US 301 in Fayetteville, a billboard read "Governor Hunt Cuts Ribbon on Doomsday."(1)

The ribbon cutting put an end to over a decade long heated battle over the routing of Interstate 95 around Fayetteville.  One that made it all the way to the steps of the United States Supreme Court.
