Rendering of the future Treasure Island

By 2036, the Treasure Island neighborhood will grow by up to 8,000 homes—many offered at below-market rates—housing more than 20,000 new residents. 

The transportation network will be designed to prioritize sustainable modes like walking, biking, and taking transit. The Transportation Authority, in its capacity as the Treasure Island Mobility Management Agency or TIMMA, is developing a number of programs and services to support transportation on the island.

Multi-Operator Transit Pass
To provide easy access to new and expanded transit on the island, we are developing a multi-operator pass to simplify transit payments for island travelers. Learn more about the latest developments on the transit pass:

Toll Affordability Program 
To help fund new ferry service, expand transit, and manage congestion for the island, motorists will pay a toll to enter and exit the Islands. The toll and new transit services are anticipated to start in 2024. 

The San Francisco Board of Supervisors, in their capacity as the TIMMA Board, approved a policy to exempt existing Treasure Island residents from paying the toll (PDF) in late 2019. Other private vehicles will be tolled when entering and exiting the island. As outlined in the Treasure Island Transportation Improvement Plan or TITIP, adopted in 2011, the proposed peak period toll is $5, with a $2.50 off-peak toll. 

TIMMA is also developing affordability programs for Treasure Island workers and future below-market rate housing residents. In September 2021, the TIMMA board approved a toll affordability program for businesses and workers that would provide a flexible cash subsidy to employers to use and distribute to their employees. The cash subsidy would be dependent on the number of full-time employees.

Ferry Service and Public Transit
SF Bay Ferry is developing a plan to transport people between Treasure Island and downtown San Francisco by 2024 via an all-electric ferry. 

An interim ferry service administered by a private developer will be available to the public in early 2022. 

In addition to the ferry service between Treasure Island and downtown, the following public transit will be available when tolling begins:

  • New East Bay bus service
  • A free on-island passenger shuttle
  • Bike share
  • Car share and programs like carpool matching 
  • Walking paths and pedestrian-only streets
