The Posey tube and the Webster Street tube are two parallel underwater tunnels connecting the cities of Oakland and Alameda, California, running beneath the Alameda-Oakland Estuary. The Posey tube is the second-oldest underwater vehicular tunnel in the US, preceded only by the Holland Tunnel. The Posey tube, completed and opened to traffic on October 27, 1928, was named after George Posey, Alameda County Surveyor during the tunnel's planning. The ventilation buildings that house the exhaust and fresh air fans are built in an art deco style.
