San Francisco County Transportation Authority 

Our mission is to make travel safer, healthier, and easier for all. We plan, fund, and deliver transportation projects to improve travel choices for residents, commuters, and visitors throughout San Francisco.

Our governing board consists of the 11 members of the San Francisco Board of Supervisors, sitting as Transportation Authority Board members. The Transportation Authority also serves as the Treasure Island Mobility Management Agency, which coordinates the transportation needs of Treasure Island.

The Transportation Authority and TIMMA have a combined staff, serving both agencies. 

Plan | We lead a range of transportation planning efforts for San Francisco

As San Francisco’s congestion management agency, we monitor travel activity on our streets and adopt plans for reducing traffic congestion, including the Treasure Island Transportation Program. We lead long-range planning to establish San Francisco’s priorities for Plan Bay Area, the region’s transportation, land-use, and housing plan, as well as local efforts like the Alemany Interchange Improvement Study.

Fund | We fund projects to improve transit, reduce congestion, and increase street safety

We oversee project implementation as our partner agencies like SFMTA, SF Public Works, and BART use this funding to improve transportation across the city.

Deliver | We deliver major capital projects

We lead major capital projects like the Folsom Street Off-Ramp Realignment Project and the Yerba Buena Island on- and off-ramps.

Community Advisory Committee 

The Community Advisory Committee provides the Transportation Authority with feedback on transportation projects and communicates about these projects to the community. The committee consists of 11 members of the public, each representing a supervisorial district in San Francisco. Committee members are appointed by the Transportation Authority Board.

The committee includes representatives from various segments of the community, such as public policy organizations, labor, businesses, seniors, people with disabilities, environmentalists, and neighborhoods, and reflects broad transportation interests. The committee is also intended to reflect the racial and gender diversity of San Francisco residents. 

Over the past decade the committee has helped the Transportation Authority guide the investment of over $1 billion in local transportation sales tax funds—matched with federal, state, and other local funds—into projects that improve transportation citywide.
