Transbay map linking San Francisco to Oakland

The Bay Skyway is designed to create a multimodal 7.5-mile transbay corridor connecting downtown San Francisco, downtown Oakland, West Oakland, Yerba Buena Island, and Treasure Island. The multi-agency project will create a safe, low-emission route for cyclists, pedestrians, and transit riders that will bypass congestion on the Bay Bridge - one of the most congested routes in the state.

In February, the Metropolitan Transportation Commission approved a $23.7 million conditional Regional Measure 3 (RM3) Safe Routes to Transit and Bay Trail program award to the Bay Skyway Phase 1 program. The award is contingent on project sponsors securing additional funding from the Senate Bill 1 Solutions for Congested Corridors Program.

Under the MTC RM3 Bay Trail award, the Yerba Buena Island Multi-Use Path project would receive $16.25 million for construction and the West Oakland Link component would receive $7.5 million of the Regional Measure 3 award.  

In November 2025, Bay Skyway partners comprised of the Transportation Authority, Bay Area Toll Authority, and California Department of Transportation (Caltrans) submitted a $71 million application to the statewide competitive Solutions for Congested Corridors Program for the Bay Skyway Project.

The Bay Skyway’s key components include:

West Oakland Link (Bay Area Toll Authority) - A 1.1-mile-long elevated pedestrian and bicycle pathway connecting Mandela Parkway in West Oakland with the existing San Francisco-Oakland Bay Bridge East Span path.

Yerba Buena Island Multi-Use Path (The Transportation Authority) -  A 1.2-mile fully separated multimodal path along Hillcrest Road and Treasure Island Road, linking cyclists and pedestrians to the Treasure Island Ferry Terminal.

Treasure Island Electric Ferry (SF Bay Ferry) - A fully electric ferry service operating between Treasure Island and the San Francisco Ferry Building.

Yerba Buena Island Transit Lane (The Transportation Authority) -  A dedicated transit lane running parallel to the Yerba Buena Island Multi-Use Path on Treasure Island Road from the Macalla Road intersection to a transit-only on-ramp to the westbound Bay Bridge. 

The Solutions for Congested Corridors Program application results are expected to be announced this summer.
