The U.S. Department of Transportation has awarded the San Francisco County Transportation Authority a $18 million grant from its Rebuilding American Infrastructure with Sustainability and Equity program for the West Side Bridges Retrofit. The retrofit project will rebuild and seismically upgrade a set of roadways and structures connecting Treasure Island and Yerba Buena Island to I-80. 

The grant completes the project’s $110 million funding plan and enables the project to move into construction in 2022. The Transportation Authority is delivering the project in partnership with the Treasure Island Development Authority, Caltrans and the Bay Area Toll Authority. The West Side Bridges Project is part of a larger infrastructure renewal effort to prepare the Islands for 8,000 units of new housing (27% of which will be affordable) and other commercial uses, over the coming decade.

“We are thrilled to receive this grant award and thank the U.S. DOT for recognizing the importance of rebuilding the infrastructure on Treasure Island to support much needed housing and sustainable travel options for residents and regional visitors alike,” said Transportation Authority Board Chair Rafael Mandelman (District 8). “Thank you also to Speaker Pelosi, Senator Padilla and Senator Feinstein for their tremendous leadership in passing the historic infrastructure investment bill and for supporting this grant. We are grateful to the President and Congress for these much-needed investments.”

Supervisor Matt Haney (District 6), whose district includes Treasure Island and who serves as Chair of the Transportation Authority’s role as the Treasure Island Mobility Management Agency, echoed Chair Mandelman’s thanks adding: “Thank you to U.S. DOT for helping Treasure Island become a showcase for safe and sustainable development. We very much appreciate President Biden and the administration’s vision for clean, equitable transportation and ensuring our investments maintain and create good-paying jobs. We will advance all of these objectives with this investment.”

In addition to rebuilding the West Side Bridges roadway, the project will add a bus priority lane on the westbound on-ramp to the Bay Bridge, and will feature several sustainable practices and materials, and local art. The project schedule calls for completion of the West Side Bridges project in 2025.
