CTC Invests $220 Million from SB1 in Highway 101 Congestion Relief for San Mateo County

CTC Invests $220 Million from SB1 in Highway 101 Congestion Relief for San Mateo County


The California Transportation Commission voted to fund the Highway 101 Managed Lanes Project today, as staff recommended on April 26. The San Mateo County Transportation Authority (TA), along with C/CAG and Caltrans, will receive $220 million in State funding to support the project designed to provide congestion relief on Highway 101 in San Mateo County.

This funding was made available through programs established by Senate Bill 1 (SB 1), the landmark statewide transportation funding legislation signed into law last year. $200 million came from the Solutions for Congested Corridors Program, and the remaining $20 million came from the Local Partnerships Competitive Program.

The project is a collaborative effort between the three agencies and would address congestion on Highway 101 by creating an express lane in each direction between Whipple Avenue in Redwood City and Interstate 380 in San Bruno. The express lanes would connect to the HOV lanes that already exist south of Whipple and extend into Santa Clara County.

The Santa Clara Valley Transportation Authority is working concurrently to convert these HOV lanes to express lanes, and received $33 million in grants from the CTC to fund those efforts. Together, the projects would create a new system of continuing express lanes that will incentivize the use of public transit, carpools, and other shared ride options, while also creating a new revenue stream for additional transportation enhancements from individuals willing to pay a fee to drive in the new lanes.

The Managed Lanes Project is expected to enter the design phase upon completion of environmental review this summer. The managed lanes are expected to open to vehicles in summer of 2021.

This allocation makes a total of four transportation projects in San Mateo County that received grants through SB 1. Caltrain received a grant totaling $164 million that will accelerate the process of fully electrifying the fleet and provide on-board Wi-Fi. SamTrans received $15 million to fund a pilot express bus program on Highway 101.


About the TA: Created to administer Measure A, San Mateo County’s ½ cent sales tax, the Transportation Authority provides funding for transportation and infrastructure improvement projects. In 2004, more than 75 percent of San Mateo County residents voted to reauthorize Measure A for an additional 25 years.
