"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. Currently, the Posey Tube carries Oakland-bound traffic under the Estuary, while the Webster Tube carries traffic bound for Alameda.

The Posey Tube is the second-oldest underwater vehicular tunnel in the US, preceded only by the Holland Tunnel." (visit link)
