A rendering of the Treasure Island development

Transportation Program Overview

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. Along with more housing, this new development includes extensive open space, hotels, restaurants, shops, and entertainment venues.

This new activity will result in tens of thousands of additional trips to and from the island each day. The Transportation Authority is developing a transportation program for the island to ensure at least 50 percent of trips are made by walking, biking, and taking transit. 

The Treasure Island Transportation Program is governed by the San Francisco Board of Supervisors in its capacity as the Treasure Island Mobility Management Agency Board.

Transportation Program Goals

Promote walking and biking: Bike lanes, pedestrian paths, and Ford GoBike stations will make biking and walking around the island safe and enjoyable.

Provide high-quality transit: More Muni service, along with new AC Transit, ferry service, and an on-island shuttle will help ensure that at least 50 percent of trips to and from the island are made using sustainable modes.

Reduce the need for car ownership and use: People who drive will pay a toll for driving on and off of the island. The cost of housing will not include parking, so people who own cars will pay for parking separately. Access to car share vehicles will make it easier to live without owning a personal vehicle on the island.

Promote affordability: Subsidized transit passes and discounts to services like car and bike share will make transit affordable and accessible to longtime residents and people living in below market-rate housing.

Transportation Programs Under Development


The estimated start date for the Treasure Island toll is 2024. 

Treasure Island residents: The San Francisco Board of Supervisors decided existing Treasure Island residents will not pay the toll. This toll exemption means Treasure Island residents will be able to drive on or off the island any number of times at any time of day and they will not pay the toll. (Read the resolution approving a toll exemption for current Treasure Island residents (PDF).

Non-residents: Other private vehicles will be tolled when entering and exiting the island. The current proposal is a $5 peak toll and $2.50 off-peak. The toll will help pay for expanded transit service and mobility improvements and will help manage congestion. Because the toll will help pay for expanded transit, we plan to have a toll in place when we start new transit service in 2024.

Treasure Island businesses/workers: Agency staff have prepared a proposed toll policy for businesses and workers on Treasure Island, based on public input and technical analysis. 

The toll policy, expected to go into effect in 2024, has the following elements:

  • Applies to all existing not-for-profit entities and existing food distribution & food service establishments 
  • Employers are provided a quarterly subsidy based on number of employees
  • Employer should prioritize compensation for low-income employees 
  • Remaining balance may be used to compensate deliveries, vendors, visitors, and/or customers
  • Employer may use the subsidy to add to a toll tag (FasTrak) balance or as cash payment
  • TIMMA will evaluate and adjust the program after 12 months in consultation with eligible employers 

We will be presenting this business/worker toll policy to the Treasure Island Mobility Management Agency Committee on September 21, 2021 at 11:00 AM.

Bus, Ferry, Walking, Biking, Shuttle

The following public transit will be available when tolling starts:

  • New East Bay bus service
  • New ferry service between Treasure Island and San Francisco
  • A free on-island passenger shuttle
  • Bike share
  • Car share and programs like carpool matching and an emergency ride home program
  • Walking paths and pedestrian-only streets

Transit Passes

Treasure Island residents in below-market rate housing will qualify for a Clipper Card at a 50 percent discount. That pass will allow unlimited rides on all Muni, AC Transit, and the Treasure Island ferry. 

Treasure Island residents in market-rate housing will be required to purchase a monthly Clipper Card at regular price.


Parking restrictions will begin in 2022. Drivers will be required to pay for metered spots on new public streets. And for residents of Treasure Island the cost of housing will not include parking. That means people who own cars will pay for parking separately.

Public engagement

The Transportation Authority is working closely with Treasure Island residents, businesses, community organizations, housing providers, island developers, and the Treasure Island Development Authority on the transportation program.
