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.

Yes, the color of your nearby fire hydrant matters...

...and here's why. You will find White, Red, Yellow and Violet colored fire hydrants pretty much everywhere.  But there's a reason for this - and it's because of the National Fire Protection Association (NFPA).  This association has issued guidelines for color coding standards for fire hydrants.  These color codes from the body of the hydrant, top of the hydrant, and in some municipalities the outlet caps are designed to allow fire fighters to know what type of system, water flow rate (Gallons Per Minute or GPM), and level of water pressure.  This guideline is known as NFPA 291 and is intended to be used universally throughout the United States. The NFPA guidelines are specific to the body and the top cap of the hydrant.  If a hydrant is WHITE or YELLOW - it means that it is connected to a public/municipal water system.  If a hydrant is RED - the hydrant is connected to a private system, typically a well.  These are most common in rural or unincorporated areas

Phase 1 of the California State Route 132 West Expressway (in the making since 1947)

On September 15, 2022, the Phase 1 of the California State Route 132 West Expressway opened in the city of Modesto from California State Route 99 west to North Dakota Avenue.  Phase 1 of the California State Route 132 West Expressway was built upon a corridor which was tentatively to designated to become the branching point for Interstate 5W in the 1947 concept of the Interstate Highway System.  The present California State Route 132 West Expressway corridor was adopted by the California Highway Commission on June 20, 1956.  Despite almost being rescinded during the 1970s the concept of the California State Route 132 West Expressway corridor lingered on for over half a century and became likely the oldest undeveloped right-of-way owned by California Transportation Commission.  Pictured above is the planned California State Route 132 freeway west of US Route 99 in Modesto as featured in the May/June 1962 California Highways & Public Works.   The history of the California State Route

Aptos Creek Road to the Loma Prieta ghost town site

Aptos Creek Road is a roadway in Santa Cruz County, California which connects the community of Aptos north to The Forest of Nisene Marks State Parks.  Aptos Creek Road north of Aptos is largely unpaved and is where the town site of Loma Prieta can be located.  Loma Prieta was a sawmill community which operated from 1883-1923 and reached a peak population of approximately three hundred.  Loma Prieta included a railroad which is now occupied by Aptos Creek Road along with a spur to Bridge Creek which now the Loma Prieta Grade Trail.  The site of the Loma Prieta Mill and company town burned in 1942.   Part 1; the history of Aptos Creek Road and the Loma Prieta town site Modern Aptos traces its origin to Mexican Rancho Aptos.  Rancho Aptos was granted by the Mexican Government in 1833 Rafael Castro.  Rancho Aptos took its name from Aptos Creek which coursed through from the Santa Cruz Mountains to Monterey Bay.  Castro initially used Rancho Aptos to raise cattle for their hides.  Following
