Project Details

The Highway 101: Carpinteria to Santa Barbara project seeks to relieve traffic congestion from Carpinteria to Santa Barbara by adding several High Occupancy Vehicle (HOV) lanes to Highway 101 in that area. This phased approach includes:

  • Widening Highway 101 to 6 lanes from Carpinteria to Santa Barbara;

  • Reconstructing overcrossings at Cabrillo Blvd. and Sheffield Road;

  • Remediating or replacing creek bridges and under crossings; and

  • Replacing existing pavement, shoulder widening and improving ramps from Casitas Pass Road to Sheffield Road.

Segment 4A (PM 1.4 to 4.6)

Phase 4A will widen Highway 101 to 3 lanes in each direction within the City of Carpinteria boundaries. The project includes new bridges over Franklin and Santa Monica Creeks along with ramp improvements at Santa Monica Road, Carpinteria Avenue, and Reynolds Avenue. There are four sound walls planned in Phase 4A.

Segment 4C (PM 7.5 to 9.2)

Phase 4C will widen Highway 101 to 3 lanes in each direction in Summerland. The project includes new bridges for the Evans Avenue and Sheffield Drive Undercrossings. Ramp improvements will occur at Sheffield Drive, Evans Avenue, and Wallace Avenue. There are two sound walls in Phase 4C.

Segments 4D and 4E (PM 9.2 to 12.3)

Phases 4D & E will widen Highway 101 to 3 lanes in each direction between Sycamore Creek in the City of Santa Barbara up to Romero Creek in Montecito (west of Sheffield Drive). Included are the reconstruction of the Hwy 101 bridges over Cabrillo Boulevard and a new southbound on-ramp (replacing the lefthand ramp removed in Phase 1). Bridges will be replaced at Montecito, San Ysidro, Oak, and Romero Creeks. Sound walls are included, and this design phase is also proposing to integrate some operational and safety improvements on Highway 101 and the ramps.
