Transportation
Treasure Island is connected to Yerba Buena Island, which has exits and entrances into and out of the San Francisco – Oakland Bay Bridge (I-80) in both directions. Travel between Yerba Buena and Treasure Islands and the rest of San Francisco is toll-free in both directions.
There is one bus line that serves the island: San Francisco Muni's bus 108. Before the Transbay Terminal was demolished, this bus line was the only Muni bus line to use the Transbay Terminal ramps, similar to the east bay Transbay buses.
When the replacement eastern span of the Bay Bridge is completed, it will carry a bikeway that connects Yerba Buena and Treasure Islands with Oakland.
