The Key System Mole was an interurban train and ferry pier on the San Francisco Bay. It served as an interchange point in the East Bay for Key System passengers traveling to and from San Francisco. It opened to passenger service in 1903 and was upgraded several times until 1933 when it was partially destroyed by a fire. Passenger service ended in 1939, and segments of the structure were partially reused in construction of the San Francisco–Oakland Bay Bridge.
