What is Yerba Buena Island?
Yerba Buena Island is a natural island located in the San Francisco Bay in between Oakland and San Francisco. Many Bay Area dwellers are familiar with the island because it connects the East and West spans of the Bay Bridge with a central tunnel. Yerba Buena Island also hosts a Coast Guard station and a small civilian population. In addition, it serves as the access point for Treasure Island, an artificially constructed island built on the shallows of Yerba Buena Island in the 1930s by the Works Progress Administration.
