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.

California State Route 153; the supposedly shortest State Highway

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

Old Stage Road; the "real" El Camino Real and predecessor route to US Route 101 on the San Juan Grade

This past month I stopped in San Juan Bautista to hike the Juan Bautista De Anza Trail on the closed Old Stage Road.  Old Stage Road as part of the Spanish El Camino Real to cross the Gabilan Range between San Juan Bautista and Salinas Valley.



Part 1; the history of El Camino Real and Old Stage Road

The Gabilan Range between what is now San Juan Bautista and Salinas Valley was first explored during the second Juan Bautista De Anza Expedition of Las Californias.  While the De Anza expedition likely crossed very close to the present alignment of Old Stage Route their exact path isn't clear.  Juan Bautista De Anza noted the following in his journal while passing near present day San Juan Bautista on March 24, 1776:

"In the valley we saw many antelopes and white grey geese.  In the same valley we found an arroyo...and then came to a village in which I counted about twenty tule huts.  But the only two people we saw were two Indians who came out to the road and presented us with thr…

Railroad Square Historic District, US Route 101, California State Route 12; Santa Rosa, California

This past November I visited the Railroad Square Historic District in Santa Rosa of Sonoma County, California.  Railroad Square is a historic corridor in downtown Santa Rosa which was created due to it being isolated due to the realignment of US Route 101.



Part 1; the history of Railroad Square and the highways of Santa Rosa

Santa Rosa is the County Seat and largest City in Sonoma County.  Santa Rosa was settled in 1833 in Alta California and was named after Saint Rose of Lima.  When California became an American State, Sonoma County was one of the original counties.  The original County Seat of Sonoma County was in Sonoma but it was soon moved to Santa Rosa by 1854.  In 1867 Santa Rosa became an incorporated City as it was one of the few major communities north of San Francisco Bay.

Railroad service arrived to Santa Rosa in 1870 by way of the San Francisco & Northern Pacific Railroad ("SF&NP").  The SF&NP began construction from Petaluma northward in 1869.  By 1…

Old US Route 101 in Salinas

This past June I visited much of what was the original alignment of US Route 101 within the City of Salinas.



Part 1; the history of US Route 101 in Salinas

Salinas is presently the largest City in Monterey County and is the County Seat.  Salinas lies within Salinas Valley and is located east of the namesake river.  Originally El Camino Real originally was routed through Salinas Valley on a course towards the Monterey Peninsula.  The route of El Camino Real was intended to solidify a path of travel between the Catholic Missions of Las Californias. In 1797 Mission San Juan Bautista was founded which led to a need for a spur of El Camino Real to be built from Salinas Valley over the Gabilan Range.  This spur of El Camino Real would become what is now Old Stage Road.  The split in the paths of El Camino Real roughly was located where the City of Salinas now sits. 

In 1804 Alta California was formed out of the larger Las Californias but the junction of El Camino Real in Salinas Valley …
