California State Route 77; the real "Shortest Signed" State Highway

Over the last two weeks I visited almost every State Highway in the San Francisco Bay Area.  The shortest State Highway by a large margin in the Bay Area is California State Route 77.


CA 77 is presently only 0.45 miles in length and is located entirely within the City of Oakland.  CA 77 begins at Interstate 880 and heads eastward on 42nd Avenue to CA 185 on 14th Street.

 
As presently completed CA 77 would rank as the fourth shortest State Highway only behind CA 225, CA 275 and CA 283.

CAhighways.org list of Shortest State Highways

CA 77 presently has a 13.4 mile portion that has not been constructed.  CA 77 as originally envisioned would have continued northeast towards Concord and would have junctions with; I-580, unbuilt CA 93, CA 24, I-680 and CA 242.  According to CAhighways.org the present route of CA 77 was designated as Legislative Route Number 233 which was approved by the State Legislature in 1953.  The legislative description of LRN 233 was changed to LRN 235 by 1957.

CAhighways.org on CA 77

CAhighways.org on LRN 235

The path of LRN 233 first appears on the 1954 State Highway Map City Insert.


The designation of LRN 235 replaces LRN 233 on the 1958 State Highway Map City Insert.



By 1963 the portion of LRN 235 between CA 17 on the Nimitz Freeway (current I-880) and LRN 105 (present CA 185) is shown completed.


During the 1964 State Highway Renumbering LRN 235 was reassigned as CA 77.


According to CA 77 the planned route of CA 77 was cut back to CA 24 in Layayette by 1975.  This is reflected on the 1977 State Highway Map City Insert.



Note; as completed in 1963 the configuration of LRN 235/CA 77 was a freeway with free flowing ramps to/from CA 17/I-880 northbound.  Said ramps were reconfigured in 2012 into the at-grade ramps present at the western terminus of CA 77.

Access to CA 77 can be obtained from I-880 via Exit 38.  Oddly High Street is signed from I-880 and not 42nd Avenue even though that is the direct connection.  From I-880 there is not CA 77 signage, the downpour was about as miserable as it looks.


From the exit ramp CA 77 begins with a left hand turn onto 42nd Avenue.  Again there is no CA 77 shields to be found.


CA 77 east travels under both travel lanes of I-880 and essentially is limited access (albeit not a freeway).



Between the northbound lanes of I-880 and on-ramp from Coliseum Way the first CA 77 reassurance shield appears.   CA 77 east even features an off-ramp to 12th Street which can be seen in the second photo below.

 

The CA 77 reassurance shield makes it the real "shortest" signed State Highway and not CA 153 which is often proclaimed as such.  My previous blog entry on CA 153 can be found below.

CA 77 east even has a second reassurance shield before it terminates at CA 185 at 14th Street.

Hi, I was researching the 42nd Ave freeway entrance for my blog and came across your page. Great photos. I am writing a page on the "Bancroft Parkway" which began at the San Leandro border on Bancroft and ended at 42nd Ave with entrance to the Nimitz (880) Freeway.

California State Route 232

This past month I drove the entirety of California State Route 232 in Ventura County. CA 232 is an approximately 4 miles State Highway aligned on Vineland Avenye which begins near Saticoy at CA 118 and traverses southwest to US Route 101 in Oxnard.  The alignment of CA 232 was first adopted into the State Highway System in 1933 as Legislative Route Number 154 according to CAhighways.org. CAhighways.org on LRN 154 As originally defined LRN 154 was aligned from LRN 9 (future CA 118) southwest to LRN 2/US 101 in El Rio.  This configuration of LRN 154 between CA 118/LRN 9 and US 101/LRN 2 can be seen on the 1935 California Division of Highways Map of Ventura County. 1935 Ventura County Highway Map According to CAhighways.org the route of LRN 154 was extended west from US 101/LRN 2 to US 101A/LRN 60 in 1951.  Unfortunately State Highway Maps do not show this extension due to it being extremely small. During the 1964 State Highway Renumbering LRN 154 was assigned CA 232.  Of n

Former US Route 101 and California State Route 1 in San Luis Obispo

Originally US Route 101 upon descending Cuesta Pass southbound entered the City of San Luis Obispo via Monterey Street.  From Monterey Street US Route 101 utilized Santa Rosa Street and Higuera Street southbound through downtown San Luis Obispo.  Upon departing downtown San Luis Obispo US Route 101 would have stayed on Higuera Street southward towards Pismo Beach and Arroyo Grande.  Notably; beginning in 1934 US Route 101 picked up California State Route 1 at the intersection of Monterey Street/Santa Rosa Street where the two would multiplex to Pismo Beach.  Pictured below is the 1 935 Division of Highways Map of San Luis Obispo County depicting the original alignments of US Route 101 and California State Route 1 in the City of San Luis Obispo.   Part 1; the history of US Route 1 and California State Route 1 in San Luis Obispo San Luis Obispo lies at the bottom of the Cuesta Pass (also known as the Cuesta Grade) which has made it favored corridor of travel for centuries.  Cuesta Pass

Former California State Route 1 over Old Pedro Mountain Road

California State Route 1 in western San Mateo County traverses the Montara Mountain spur of the Santa Cruz Mountains.  In modern times California State Route 1 passes through Montara Mountain via the Tom Lantos Tunnels and the highway is traditionally associated with Devils Slide.  Although Devils Slide carries an infamous legacy due it being prone landslides it pales in comparison to the alignment California State Route 1 carried prior to November 1937 over Old Pedro Mountain Road.   Old Pedro Mountain Road opened to traffic in 1915 and is considered one of the first major asphalted highways in California.  Old Pedro Mountain Road clambers over a grade from Montara towards Pacifica via the 922 foot high Saddle Pass.  Pictured above an overlook of Old Pedro Mountain Road facing southward towards Montara as it appears today.  Pictured below it the same view during June 1937 when it was part of the original alignment of California State Route 1.  Today Old Pedro Mountain sits abandoned a
