A rendering of the Treasure Island development


By 2035, 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.

Proposed Treasure Island Transit Pass

The Treasure Island Transit Pass will be accessible to anyone living or working on Treasure Island or Yerba Buena Island. The pass will be available on Clipper Card.

  • Unlimited rides on all Muni, AC Transit, and the Treasure Island ferry
  • Monthly cost will be based on household eligibility (market or below-market rate)
  • Required for each new market-rate household
  • Optional for below market-rate and longtime households to purchase at a 50 percent discount

Proposed Affordability Program

Residents who live in below market-rate households will qualify for the Affordability Program, which is under development.

Proposed Toll Policy 

Tolls incentivize smart choices on when and how people travel. Toll revenue will fund new and expanded island transit services and mobility improvements.

  • Current Treasure Island residents will be exempt from the toll
  • Private vehicles will be tolled when entering and exiting the island 
  • Tolling will use FasTrak and other easy on-Island toll payment options
  • The Affordability Program (under development) will include toll credits and/or discounts
