# California State Route 34

State Route 34 (SR 34) is a state highway in the U.S. state of California. It runs through Ventura County from Rice Avenue (State Route 1) in Oxnard to State Route 118 in Somis.

## Route description

SR 34 is part of the California Freeway and Expressway System, and portions of the route in Oxnard and Camarillo are part of the National Highway System, a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.
It starts on the west at the intersection of Rice Avenue and Fifth Street in Oxnard. It continues east then northeast on Fifth Street until it intersects Pleasant Valley Road in Camarillo. After continuing east on Pleasant Valley Road a short distance, it turns north onto Lewis Road until the intersection with Las Posas Road at the north city limit of Camarillo where Route 34 continues straight ahead as Somis Road. It ends at Route 118 near Somis. This route originally began in Port Hueneme, but in 1965, the portion from Port Hueneme to Route 1 was deleted. Nevertheless, Route 34 mileposts add on these additional 4 miles (6.4 km) along the signed route.
The route parallels the Union Pacific Railroad's Coast Line, which carries Coast Starlight, Pacific Surfliner and Ventura County Line passenger trains, for almost its entire current length.

## History

In 1933, a road from Hueneme to near Somis, going through Oxnard and Camarillo, was added to the state highway system. This road was numbered as Route 153 in 1935. In the 1964 state highway renumbering, SR 34 was defined with this routing, ending at SR 118 on the eastern side. In 1965, the highway from Port Hueneme to SR 1 was removed from the state highway system. The part of the highway in Oxnard was authorized by the state legislature to be turned over to the city of Oxnard in 2008.

## Future

According to the 2017 Caltrans District 7 Transportation Concept Report for State Route 34, State Route 34 is on the list of routes recommended for relinquishment.

## Major intersections

Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers to an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, see California postmile § Official postmile definitions). Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in Ventura County.
