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 third shortest State Highway only behind CA 275 and CA 283.

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.

California State Route 112, 61 and 260 (a functional CA 61)

On a recent trip to the Bay Area I drove/clinched numerous highways.  Some of them had oddities like not being signed, not completed as planned or even relinquished segments.  None was as strange as California State Routes 112, 61 and 260 which all essentially serve as a signed version of CA 61.


As completed CA 112, 61 and 260 serve as a functionally signed (mostly...) CA 61 which starts at CA 185 in downtown San Leandro and traverses northwest through Alameda to downtown Oakland at I-880.  Below is a historic summary of each highway which serves to make up the signed portions of CA 61.

CA 112, CA 61 and CA 260 were all part of Legislative Route Number 69 which was added to the State Highway system in 1925 according to CAhighways.org.  LRN 69 originally only was part of the highway system from LRN 1 (future US 101) in San Rafael eastward to Point San Quentin where the Richmond-San Rafael Bridge would later be located.  LRN 69 was extended in 1933 which extended it southward to LRN 5 i…
