This route was LRN 92, defined in 1933. It was not signed. This route exists in the State Historic Park.

Signed Route 153 was not defined as part of the initial state signage of routes in 1934. It is unclear what (if any) route was signed as Route 153 between 1934 and 1964.

Status Status

Note: This is one of five routes in California with "backward postmiles" -- that is, PM ED 0.000 is at the Eastern end of the route, and increase as the route goes West. The historical reason for this is unclear, unlike with other "backward postmile" highways that often transitioned from S/N to W/E (such as I-580).

This route has only one sign, at its start. Below the sign is another sign noting this is California's Shortest State Highway (although it really isn't; another highway, Route 283, has that honor).

Pre-1964 Legislative Route Pre-1964 Legislative Route

In 1933, Chapter 767 defined the route from "Hueneme to Montalvo-San Fernando Road near Somis via Oxnard and Camarillo" to be a state highway. In 1935, this route was added to the highway code as LRN 153, with the following definition:

"Hueneme to [LRN 9] near Somis via Oxnard and Camarillo"

In 1959, Chapter 1062 changed the definition to delete the specific routing: "…near Somis via Oxnard and Camarillo".

This route is present-day Route 34. According to a 1943 USGS map, this ran along Wood Road to Oxnard Road (5th Street), and then along 5th, Pleasant Valley, and Lewis (Somis Road) to Somis and Sign Route 118. This appears to have been signed as a spur of Sign Route 118 in the 1940s, perhaps until 1964.
