Under the Oakland Estuary: History and Virtual Tour of the Posey Tube
Join CPF for this lunch-time presentation and discussion about the George A. Posey Tube, which was the first underwater automobile tunnel built in the western United States. Completed in 1928 under the Oakland Estuary connecting Oakland and Alameda. The Posey Tube was an innovative structure for its time, built to resolve significant transportation issues, and its portals are striking examples of Art Deco architecture.
