Former California State Route 109 on Interstate 8 west of Interstate 5

While visiting the San Diego area I traveled to the west terminus of Interstate 8 near Ocean Beach.  I-8 west of I-5 is somewhat unique given it was originally designated as part of the first California State Route 109.


I-8 west of I-5 is known as the "Ocean Beach Freeway" and has served as the western terminus at Sunset Cliffs Boulevard since being transferred from the first CA 109 in 1972.  This segment of I-8 was originally adopted in 1959 as part of Legislative Route Number 286 between Sunset Cliffs Boulevard in the Ocean Beach neighborhood of San Diego east to LRN 2 (US 101).

LRN 286 appears on the 1960 State Highway Map City Insert as an unbuilt State Highway using the following route west of LRN 2/US 101:

-  Barnett Avenue from Pacific Highway (former US 101) to Midway Drive.
-  Midway Drive over the San Diego River to Sunset Cliffs Boulevard.  Midway Drive north the San Diego River is now Mission Bay Drive and Sunset Cliffs Boulevard is now Sea World Drive.

The 1960 State Highway City Insert can be viewed below.

The legislative designation of LRN 286 was changed to CA 109 during the California State Highway Renumbering.  The route of CA 109 appears on the 1964 State Highway Map is shown as a western connector to the already completed section of I-8 on US 80 (former LRN 12).  The new planned route of CA 109 aligns to what ultimately became the western segment of I-8.  These changes can be seen by comparing the 1963 State Highway Map City Insert to the 1964 edition.

The route of CA 109 is shown completed on the 1970 State Highway Map but does not appear to have been signed.

As noted above CA 109 was approved as a Non-Chargeable Interstate and became the western segment of I-8 in 1972.

I-8 appears over what was CA 109 on the 1975 State Highway Map City Insert.

The CA 109 designation was recycled in 1984 as part of a new connector route in East Palo Alto.  More on the second CA 109 can be found below.

My approach to the former CA 109 segment of I-8 was from I-5 north.  From I-5 north the route I-8 west is signed with a control city of "Beaches."



Traffic from I-5 north onto I-8 west merges in from a left approach.  I-8 west on the former CA 109 has no exits and runs along the San Diego River to a terminus at Sunset Cliffs Boulevard.  I-8 does have "end" signage at it's terminus.  Traffic in the right lane is directed onto Sunset Cliffs Boulevard whereas left lane traffic is directed onto Nimitz Boulevard.

California State Route 58/Old California State Route 178 west of CA 43

This past week I drove California State Route 58 west of CA 43 in Kern County over the Temblor Range and La Panza Range to US Route 101 near Santa Margarita of San Luis Obispo County.


CA 58 west of Bakersfield and CA 99 in general is a mostly two-lane highway that traverses some very remote territory of Central California.  I chose to cover CA 58 west of CA 43 specifically due to the changes in the alignment that are to come when the West Side Parkway connects to the Centennial Corridor project.  The Centennial Corridor will connect CA 58 west of CA 99 to the already completed segment of Freeway on the West Side Parkway.

CA 58 from Barstow west to Bakersfield was carved out of what was US Route 466 during the 1964 State Highway Renumbering.  CA 58 west of Bakersfield to Santa Margarita was carved out of what was part of CA 178.  The change from CA 178 to CA 58 west of Bakersfield to Santa Margarita can be ob…

California State Route 225; the Zombie Highway of Santa Barbara and presently shortest in California

This past month I visited the Santa Barbara Area and drove the many short State Highways located there.  The shortest and the strangest is the 0.081 mile California State Route 225.


As noted above CA 225 is presently only 0.081 miles in length and is located completely on Castillo Street in Santa Barbara between Montecito Street and US 101/CA 1.  Fortunately the Caltrans Post Mile Tool illustrates that CA 225 still exists despite almost being relinquished to death.



At present moment CA 225 is the shortest State Highway in California.  By the definition of actual field mileage the following State Highways are the five shortest in California:

1.  CA 225 at 0.081 miles
2.  CA 275 at 0.14 miles
3.  CA 283 at 0.36 miles
4.  CA 77 at 0.40 miles 
5.  CA 153/CA 265 at 0.50 miles each

The origin of CA 225 was back in 1933 when Legislative Route 150 was added to the State Highway system as a loop of US 101/LRN 2 between Santa Barbara east to near Montecito according to CAhighways.org.  As orig…

California State Route 118

This past month I drove the entirety of California State Route 118 from Ventura County east into Los Angeles County.


CA 118 is a major 47 mile State Highway which begins in the City in Ventura County and traverses east into Los Angeles County by way of Simi Valley and Santa Susana Pass.  From Santa Susana Pass CA 118 continues eastward through San Fernando Valley within the City of Los Angeles and terminates at Interstate 210.  CA 118 contains within it's right-of-way some of the most historic highway corridors in California history.

The precursor route of CA 118 was Legislative Route Number 9 which was first added to the State Highway System during the First State Highway Bond Act of 1909.  The original definition of LRN 9 was from San Bernardino westward to LRN 4 in San Fernando. LRN 9 was extended westward to LRN 2 near Montalvo (modern day Ventura) in 1933.

In a August 1934 Department of Public Works Guide the Signed State Highways were announced.  CA 118 was announced to be a…
