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.

TRANSPORTATION AUTHORITY RELEASES LOMBARD “CROOKED STREET” STUDY
The 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
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
The 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.
TRANSPORTATION AUTHORITY RELEASES 2016 ANNUAL REPORT
2016 was another busy year for the Transportation Authority as we planned, funded and delivered transportation improvements citywide.
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.
TRANSPORTATION AUTHORITY BOARD APPROVES ENVIRONMENTAL REPORT, SELECTS DESIGN
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
On 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 STUDY EXPLORES SAFETY IMPROVEMENTS
The 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.
NEIGHBORHOOD TRANSPORTATION IMPROVEMENT PROGRAM (NTIP)
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.

MyStreetSF Projects Map
From signals to streetcars, bicycles to boulevards, from pedestrian safety to paving, the Transportation Authority provides funding for hundreds of transportation projects citywide. The MyStreetSF interactive map shows projects currently underway, proposed, and recently completed that are funded by, or prioritized for funding by the Transportation Authority, as well as those for which the we provide some level of oversight, in our role as Congestion Management Agency for San Francisco. The MyStreetSF interactive map allows you to search for projects by location, Supervisorial District, project type (e.g., bicycle, pedestrian safety, transit rehabilitation), project sponsor, or timeline. Click on a project on the map to see key information (e.g., short description, schedule, cost) and a link to the project page and/or project sponsor’s main page. The map page also includes information on city-wide projects and programs like Bicycle Education and Outreach. READ MORE
