US 101: Corridor System Management Plan
(Ventura and Santa Barbara Counties)
The US 101 CSMP will assess current performance, identify causal factors for congestion, and based on testing of alternative improvement scenarios (typically through micro or macro-simulation) propose the best mix of project improvements, strategies and actions to restore throughput, improve travel times, increase reliability and safety, and preserve the corridor. The Corridor is not limited to project boundaries and includes all transportation components (not just highways) that affect mobility on a major travel path.
The portion of the State Highway System to be included in this CSMP covers two counties and two Caltrans Districts; Santa Barbara County in District 5 and Ventura County in District 7. The limits of this corridor study cover 47 miles from the Rice Avenue interchange (postmile 20.26) in Ventura County to the Winchester Canyon interchange (postmile 27.2) in Santa Barbara County. This segment of US 101 is surrounded by urban and rural/agricultural land uses.
