Ventura Freeway

The Ventura Freeway is one of the principal freeways in Southern California, United States, connecting Ventura County and the southern San Fernando Valley in Los Angeles County. While it runs through an east–west corridor from the Santa Barbara–Ventura county line to the City of Pasadena, most of it is signed as part of the north-south U.S. Route 101. The Ventura Freeway's eastern segment from its intersection with the Hollywood Freeway in the southeastern San Fernando Valley (the Hollywood Split) to its terminus at the Foothill Freeway (Interstate 210) in Pasadena is signed as State Route 134 (SR 134). In addition, the segments from the Santa Barbara County line to Sea Cliff, and from Solimar Beach to Oxnard, are concurrent with State Route 1 (SR 1), although no signs mention SR 1 there.

The US 101 segment was built in the late 1950s and opened on April 5, 1960. The SR 134 segment was built by 1971. Before the construction of the new alignment in 1971, most of the portion was known as the Colorado Freeway after nearby Colorado Boulevard, a historic thoroughfare in Pasadena and northeastern Los Angeles.
