George Wallace Tunnel

The George Wallace Tunnel in Mobile, Alabama, passes beneath the Mobile River and serves as a key traffic corridor for Interstate 10. With two tubes of two lanes each, it connects downtown with Blakeley Island. The tunnel segments were prefabricated at the ADDSCO shipyard between 1969 and 1973, then floated into place, flooded, joined together, and later drained. On the western side, the tunnel emerges beneath Royal Street into an elevated roadway built on pillars, while on the eastern side a ramp leads onto the bridge toward Mobile Bay. A historic highlight nearby is the reconstruction of Fort Condé, whose foundations were discovered during construction.
