Un-constructed California State Route 235

On my frequent travels through Stockton over the years on California State Route 99 and Interstate 5 I have noted the oddity of un-constructed California State Route 235.  CA 235 was meant to connect CA 99 to I-5 via what is now Hammer Lane.


According to CAhighways.org the precursor route to un-built CA 235 was planned as LRN 260 which was adopted in 1959.

The planned route of LRN 260 first appears on the 1960 State Highway City Insert and is shown north of Stockton intersecting Lower Sacramento Street and Thorton Street heading west from US 99/US 50/LRN 4 to LRN 238 (future I-5).

When LRN 260 was initially designated it wasn't long before Signed County Route J8 had been applied over Hammer Lane west from US 99/US 50 to Thorton Street in 1960.  J8 continued northward onto a terminus in south Sacramento.

At the time LRN 260 and CR J8 had been created Hammer Lane only existed west from US 99 to Thorton Street.  By the 1964 State Highway Renumbering LRN 260 had been re-designated as part of the future CA 235.  This change can been seen by comparing the 1963 State Highway Map City Insert to the 1964 Edition.

For reference even the 1935 Division of Highways Map of San Joaquin County shows Hammer Lane extending west from US 99/US 50 to Thorton Street.

According to CAhighways.org before Hammer Lane was extended to I-5 the traversable route of un-built CA 235 was listed as Eight Mile Road.  According to CAhighways.org San Joaquin County dropped interest in CA 235 November of 1993 when Eight Mile Road was adopted as a County Maintained arterial street.  Interestingly the un-built CA 235 shows on the 1990 State Highway Map City Insert still being aligned over Hammer Lane.

For reference Hammer Lane appears to have been completed to I-5 was the route is shown extended west to the Interstate on Historicaerials.com by comparing the 1977 topographical map of Stockton to the 1980 edition.

Despite not being actively sought by San Joaquin County the planned route of CA 235 never has been legislatively dropped and appears on the 2005 State Highway Map City Insert.

For reference Hammer Lane is accessible from CA 99 Exit 258 and I-5 Exit 478.  The photos below are from CA 99 northbound approaching Hammer Lane.

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
