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). The Transportation Authority was designated Treasure Island Mobility Management Agency (TIMMA) in 2014, charged with planning for sustainable mobility on Treasure Island, coordinating new ferry and regional bus service, on-island shuttle, bike share, and car share opportunities.

The Transportation Authority's DBE/LBE event, March 2017On March 20 the San Francisco County Transportation Authority hosted an event for Disadvantaged Business Enterprises (DBEs) and Local Business Enterprises (LBEs) to highlight upcoming procurements.

The event highlighted several key SFCTA contract opportunities, related to:

  • Yerba Buena Island (YBI) West Side Bridges and YBI Southgate Road Realignment Improvements
  • On-call Transportation Modeling and Technology Services
  • I-280/Balboa (Ocean/Geneva) Ramps
  • U.S. 101/I-280 High Occupancy Vehicle/High Occupancy Toll Lane
  • Treasure Island Tolling
  • Treasure Island Autonomous Shuttle Pilot

The event also featured several contracts from Caltrain and San Francisco Public Works. SFMTA and Caltrain met with attendees to talk about their DBE/LBE programs.

More information about the March 20 event, including a list of attendees and a slide presentation with details about each upcoming procurement is posted on the Available Contracting Opportunities section of our website.


Looking down Lombard Street towards LeavenworthThe Lombard “Crooked Street,” with its distinctive switchbacks, flowers, and vistas draws visitors from both around the world and locally. As overall tourism to the street has increased in recent years, issues of vehicle and pedestrian crowd control have become more challenging.

The Transportation Authority on Feb. 16 released the “Lombard Study: Managing Access to the “Crooked Street.”

The report details four recommended strategies for further planning, analysis and development. These strategies are:

  • Improved Enforcement of Existing Regulations
  • Engagement of Tourism Industry as Partners in Visitor Management
  • Engineering and Signage Enhancements
  • Reservations and Pricing System for Vehicles: Admission Fee with a Discount for Advanced Reservations

Follow this link to learn more about the study and download a copy of the report.

Each of the recommended solutions involves very specific next steps and differing timelines and will need to be adopted by the Transportation Authority Board in order to move forward. READ MORE

Transportation Authority Helps Fund First of Its Kind Streetscape Project

Ribbon-cutting to open Mansell Streetscape ProjectThe San Francisco Recreation & Parks Department on February 4 opened the Mansell Streetscape, a $7 million project to convert two busy lanes of vehicle traffic to permanent pedestrian- and bicycle-only pathways in McLaren Park.

The San Francisco County Transportation Authority helped fund this first-of-its-kind project with half-cent for transportation sales tax, Proposition AA vehicle license fees and regional grants.

Thanks to Commissioners Malia Cohen, Ahsha Safai and Hillary Ronen, as well as former Commissioners John Avalos and David Campos for their support. Thank you to the San Francisco Municipal Transportation Agency for support on this transformational project.

Input and advocacy from the Portola, Excelsior and Visitacion Valley neighborhoods was also crucial in moving this project forward. Thank you to all those community members who gave their time and energy.

2016 Annual Report cover2016 was another busy year for the Transportation Authority as we planned, funded and delivered transportation improvements citywide.

Download a copy of the agency’s 2016 Annual Report for details.

Highlights include construction of the agency’s first major capital project: the new westbound I-80 on- and off-ramps connecting Yerba Buena Island/Treasure Island to the San Francisco-Oakland Bay Bridge. Other major efforts during the year were the certification of the Environmental Impact Report for Geary Bus Rapid Transit; launching a novel crowding reduction program with BART; and initiating a framework for major transit investments with Subway Vision.

Meanwhile, the agency made strides working side-by-side with residents on neighborhood-scale planning projects across the city to improve access, transit performance and the street network.


Geary BRT visualization

The San Francisco County Transportation Authority Board—comprised of members of the San Francisco Board of Supervisors—unanimously approved the Geary Bus Rapid Transit Project design and the Final Environmental Impact Report (EIR) at their meeting on Thursday, January 5, 2017.

The ultimate project design approved by the Transportation Authority reflected significant public input and culminated more than eight years of outreach by the project team to residents, community leaders, advocates and merchants from the Outer Richmond to Downtown.

Community feedback throughout the outreach process, which included over 260 stakeholder meetings, resulted in:

  • Preserving a local bus stop at Collins Street and Rapid stop at Laguna Street;
  • Retaining the pedestrian bridge at Webster Street;
  • Preserving merchant parking in the Richmond District, including at Spruce Street, where all existing parking and loading will be maintained with a local-only bus stop; and
  • Adding more safety improvements to intersections with high collision rates for pedestrians and cyclists.

New Westbound I-80 Yerba Buena Island Ramps Opened Saturday, October 22, 2016

I-80 YBI East-side ramps in serviceOn Saturday, October 22, 2016, the San Francisco County Transportation Authority (SFCTA), in coordination with the California Department of Transportation (Caltrans) and Treasure Island Development Authority (TIDA), opened the new westbound I-80 on- and off-ramps that connect Yerba Buena Island (YBI) and Treasure Island (TI) to the San Francisco-Oakland Bay Bridge.

The new westbound on- and off-ramps are in different locations than the current westbound ramp which means that motorists will need to make adjustments. READ MORE


Alemany interchange aerial photoThe Alemany Interchange—where U.S. 101, I-280, Alemany Boulevard, Bayshore Boulevard, San Bruno Avenue and local streets intersect—presents challenges to pedestrian and bicycle safety.

At Commissioner David Campos' request, the Transportation Authority is working with neighboring communities, led by the Portola Neighborhood Association, to make the area safer and more accessible to all travelers.

Transportation Authority staff are coordinating with SFMTA planners and engineers and Caltrans staff to develop potential circulation and safety enhancement projects for the area. Community outreach is also underway to obtain input on the various improvement options.

The Alemany Interchange Improvement Study is just one of several efforts under the Transportation Authority’s Neighborhood Transportation Improvement Program (NTIP), which funds neighborhood transportation planning efforts and capital projects in every district in San Francisco. The program was developed through the Transportation Authority’s 2013 Countywide Transportation Plan to strengthen the pipeline of projects at the neighborhood level, particularly in underserved areas and Communities of Concern.

See where else NTIP work is taking place across San Francisco and let us know your ideas for the next update of the San Francisco Transportation Plan, now underway.

The Neighborhood Transportation Improvement Program (NTIP) funds community-based neighborhood-scale planning efforts, especially in underserved neighborhoods and areas with vulnerable populations (e.g. seniors, children, and/or people with disabilities).

The NTIP was developed in response to mobility and equity analysis findings from the San Francisco Transportation Plan (SFTP), the city’s 30-year blueprint guiding transportation investment in San Francisco, and the Transportation Authority Board's desire for more focus on neighborhoods, especially on Communities of Concern and other underserved neighborhoods.

The SFTP found that walking, biking and transit reliability initiatives are important ways to address socio-economic and geographic inequities.

The NTIP is made possible by the Transportation Authority through grants from San Francisco's half-cent sales tax for transportation.
