US 101 High Occupancy Vehicle (HOV) Widening and Rehabilitation, Segments 4D and 4E

This collaboration between SBCAG and Caltrans is the last phase of a four-phase strategy for providing HOV lane continuity in northern Ventura and southern Santa Barbara counties. With the completion of this project, 30 lane-miles of new HOV lanes will be added on the US 101, which will be crucial in relieving the congested conditions this portion of the US 101 experiences as a critical connection for travel and goods movement between San Jose and Los Angeles. Regionally, the US 101 is the only viable route for travel between Santa Barbara and Ventura counties. It also serves as an alternative route to Interstate 5 when it is closed by weather or emergencies.

The Segment 4D/4E Project (Southbound 101-PM 9.1/12.3) will complete the gap on US 101 by adding one High Occupancy Vehicle (HOV) lane in each direction, replace bridges over three creeks, and add 40-year long-life pavement.

Completion of the improvements have been designed to reduce congestion and delay, improve safety and operations, accommodate increased and future person throughput, and improve travel time reliability. Upon completion, US 101 will be a continuous 60-mile, six-lane facility stretching from State Route (SR) 33 in Ventura County to Fairview Avenue in the City of Goleta. The completion of the gap on US 101 with HOV lanes is matched by peak-hour passenger rail service from Ventura County from the approved multimodal corridor plan.

MNS has been providing design engineering and surveying services since 2015 for this project. Design tasks include preparing final design documents (PS&E) on construction area signs, motorist information sheets, and signages and striping.

SBCAG has requested funding from the Local Partnership Program (LPP) and in partnership with Caltrans from the Solutions for Congested Corridors Program (SCCP). SBCAG and Caltrans will be providing State Highway Operation and Protection Program (SHOPP) and Measure A sales tax funding to match this TCEP Cycle 2 request. Additionally, SBCAG is programming Regional Surface Transportation Program (RSTP) and LPP Formula funding for completion of the corridor.
