Welcome to the San Francisco County Transportation Authority

Created in 1989, the Transportation Authority is responsible for long-range transportation planning for the city, and it analyzes, designs and funds improvements for San Francisco's roadway and public transportation networks. The Transportation Authority administers and oversees the delivery of the Prop K half-cent local transportation sales tax program. It also serves as the designated Congestion Management Agency (CMA) for San Francisco under state law, and acts as the San Francisco Program Manager for grants from the Transportation Fund for Clean Air (TFCA).

Transportation Authority Prop K funds in line to buy new Muni Metro vehicles

Mayor Lee signs the contract for new Muni light rail vehiclesEarlier this month the San Francisco Board of Supervisors approved a contract that allows the San Francisco Municipal Transportation Agency (SFMTA) to purchase up to 260 new light rail vehicles for systemwide expansion and the Central Subway. On Friday, September 19, Mayor Ed Lee signed a contract with the manufacturer to begin production of the vehicles, which will dramatically increase Muni performance. The first vehicles are expected to arrive in late 2016. The SFMTA will use a number of fund sources to buy the vehicles, including up to $154 million in Prop K sales tax funds programmed by the Transportation Authority. The SFMTA also plans to use over $270 million in Prop K funds over the next six years to help replace its entire bus fleet. Replacing the bus fleet will result in the single biggest impact to increase Muni performance.
