The Transportation Authority Board acting in its capacity as the Treasure Island Mobility Management Agency also re-elected District 6 Supervisor Matt Dorsey and Supervisor Mandelman as its Chair and Vice-Chair, respectively.

At the January 23 Transportation Authority Board meeting, Executive Director Tilly Chang presented the agency’s 2023 Annual Report. Among the agency’s major accomplishments were the completion of the Yerba Buena/I-80 Southgate Interchange Project and groundbreaking for the West Side Bridges Project. The West Side Bridges and upcoming Hillcrest Road Improvement project will re-build the bridges and roadways connecting Treasure Island to the San Francisco-Oakland Bay Bridge and add a regional multi-use pathway as part of the Bay Skyway Phase 1 transbay program that links bicyclists and pedestrians from the east bay to Treasure Island, and to San Francisco’s Ferry terminal via clean electric ferries.
The Transportation Authority will pursue several important initiatives in 2024, including advancing citywide and neighborhood transportation plans and studies:
- Bayview Caltrain Station Location Study
- Geary/19th Avenue Subway Regional Connections Study
- District 1 Multimodal Study
- District 2 Safety Study
- Walter U Lum Public Space Study
- District 4 Community Shuttle Study
- Mission Bay School Access Plan
- Inner Sunset Multimodal Safety and Access Study
- Brotherhood Way Safety and Circulation Plan
The Transportation Authority will also be working collaboratively on the delivery of Caltrain’s Electrification Project, exploring a potential regional transportation funding and transit reform measure for 2026, advancing major capital project funding plans for The Portal (Caltrain/High-Speed Rail Extension to Salesforce Transit Center), supporting Muni and BART capital programs, as well as providing input on autonomous vehicle policies and legislation.
The Treasure Island Mobility Management Agency will be supporting the existing neighborhood and the more than 8,000 new housing units planned, by updating the congestion management features of the Treasure Island Transportation Improvement Program, in consultation with Island residents and other community members. This includes providing options to promote walking and biking, providing frequent and reliable transit, improving Muni bus stops and ferry facilities, and managing vehicle congestion. The Treasure Island Transportation Improvement Program’s goal is to make Treasure Island one of San Francisco’s most walkable, affordable and transit rich neighborhoods, supporting overall community health and livability.
The Transportation Authority and TIMMA Boards each consist of the 11 members of the San Francisco Board of Supervisors, who elect a chair and vice-chair each January and act as agency Board Members.
