The project will construct a 7.5-mile extension of existing High Occupancy Vehicle (HOV) lanes on US 101 in Carpinteria and Santa Barbara County. Additional construction includes sound wall installation, creek crossing improvements, and rebuilding interchanges at Sheffield Drive and Cabrillo Boulevard. The project is part of one phase of a four-phase strategy for providing HOV lane continuity in northern Ventura and southern Santa Barbara counties. The remaining segments in and near the city of Santa Barbara are partially funded.
Traffic volume is overwhelming the existing capacity of the U.S. 101 during weekday and weekend peak periods. The project is expected to reduce congestion, decrease vehicle travel times, and facilitate the flow of goods and services, as well as promote a shift from single-occupancy vehicle trips to carpool, vanpool, and bus travel. The interchange improvements will enhance safety for automobile drivers, freight carriers, bicyclists, and pedestrians. The addition of the HOV lanes will provide better collision response times for first responders and prevent secondary collisions.
The project directly addresses racial equity and reduces barriers to opportunity for residents of disadvantaged communities in Ventura and Santa Barbara counties. Due principally to the high cost of local housing in southern Santa Barbara County, significant numbers of low-income workers rely heavily on this corridor to commute daily from lower-cost homes in Ventura County into employment centers in southern Santa Barbara County.
