The November 2024 election marked the 35th anniversary of the San Francisco County Transportation Authority. In 1989, city voters passed Proposition B, approving the first half-cent transportation sales tax expenditure plan and creating the Transportation Authority, the agency charged with its administration and overseen by the 11 members of the Board of Supervisors sitting in their capacity as the Transportation Authority’s Board of Commissioners.

San Francisco residents share their transit experiences with projects we’ve helped fund through our voter-approved half-cent sales tax for transportation, ranging from neighborhood-scale improvements to capital projects.
