Scenic Highway System, but it is not officially designated as a scenic highway by the California Department of Transportation. History The route was opened in 1897. Before the construction of US 101, it was part of the main highway between Los Angeles and Santa Barbara. Originally, State Route 150 followed the alignment of State Route 192 through the Santa Barbara foothills and climbed up San Marcos Pass via the present-day route of State Route 154 before heading west on State Route 246, passing through Santa Ynez, Solvang, and Buellton and ending in Lompoc at State Route 1 (Cabrillo Highway). The only current remnants of that routing are at the mileage signs for westbound State Route 150, which have the control city as Santa Barbara west of Santa Paula, even though SR 150 currently ends east of the city.
