The San Francisco County Transportation Authority, in partnership with the Treasure Island Development Authority, Caltrans and the Bay Area Toll Authority announced the start of construction on the Hillcrest Road Improvement Project.
The nearly $38 million project, expected to be completed by 2027, is funded by state and local grants and rebuilds Hillcrest road to be more resilient, consistent with modern design standards and safer for all travelers, particularly by creating a space for a future dedicated multi-use path for people biking and walking. Funding sources include the Infill Infrastructure Grant (a state grant to the Treasure Island Development Authority from Housing and Community Development), Proposition K Local Sales Tax (administered by the Transportation Authority), SB 1 Local Partnership Program Formulaic Program funds (programmed by the California Transportation Commission), and Treasure Island Development Authority
“The new roadway provides a much improved connection between the West Side Bridges Project and the Southgate Road Interchange Improvement Project as well as with the Bay Trail via the San Francisco-Oakland Bay Bridge,” said Transportation Authority Board Chair and District 8 Supervisor Rafael Mandelman. "Thank you to all of our funding and project delivery partners for their support in creating a safer, more multi-modal Hillcrest Road for the growing neighborhoods on Yerba Buena and Treasure Islands."
Led by the Transportation Authority, the Hillcrest Road Improvement Project will upgrade the roadway to modern roadway and seismic standards and provide additional space for bicyclists traveling between the Islands and east span of the Bay Bridge. The project enables construction of a future multi-use path for active transportation users, anticipated to be delivered through the Bay Skyway phase 1 transbay project linking West Oakland to Treasure Island.
The project features:
- Improved resilience and safety for roadway infrastructure built to modern highway design standards for travelers of all modes
- A new roadway for two vehicular travel lanes, shoulders and space for a future multi-use path
- Two retaining walls (with stormwater drainage and art) set further into the hillside above Hillcrest Road to support the new roadway and multimodal facilities
- Accommodation for the future Yerba Buena Island Multi-Use Pathway Project, which is a future 1.2 mile, two-way Class 1 Multi-Use Pathway (MUP) that will extend from the Bay Bridge East Span bicycle/pedestrian landing on Yerba Buena Island to the Treasure Island Ferry Terminal. The future MUP is an essential element of the regional Bay Skyway project that will provide seamless bicycle and pedestrian access from West Oakland to San Francisco.
Project’s benefits:
- Improved West Side Bridges and Southgate Road connection
- Improved local and regional connectivity for travelers of all modes
- Improved seismic safety for the project’s retaining wall and roadbed that will accommodate the upcoming 1.2 mile Multi-Use Pathway project
- Supporting infrastructure for the growing neighborhoods and economic development of Treasure Island and Yerba Buena Island
- Support for San Francisco’s economic recovery through creating and maintaining almost 500 well-paying jobs
“This project marks an important milestone in the development of Yerba Buena Island, improving safety and access for travelers of all modes,” said Treasure Island Mobility Management Agency Chair and District 6 Supervisor Matt Dorsey. “Hillcrest Road will enable tens of thousands of additional trips to and from the Island each day serving local residents, businesses, and visitors.”
The project is the fifth partnership project among federal, state, regional and local agencies who previously collaborated to deliver:
- I-80/Yerba Buena Island East Side Ramps Project (Opened October 2016)
- I-80/Yerba Buena Vista Point Lookout (Opened May 2017)
- I-80/Yerba Buena Southgate Road/Interchange Project (Opened May 2023)
- I-80/Yerba Buena West Side Bridges Project (underway, completion anticipated in 2026)
