Yerba Buena Island sits in the San Francisco Bay between San Francisco and Oakland, California. The Yerba Buena Tunnel runs through its center and connects the western and eastern spans of the San Francisco–Oakland Bay Bridge. It has had several other names over the decades: Sea Bird Island, Wood Island, and Goat Island. The island is named after the town of Yerba Buena, which was named for the plant of the same name that was abundant in the area.
