Driving through The George Wallace Tunnel at Night - Mobile, Alabama

The George Wallace Tunnel is a pair of road tunnels that carry Interstate 10 through Mobile, Alabama from the city's downtown, going beneath the Mobile River, and emerging on Blakeley Island where they join the Jubilee Parkway over Mobile Bay.
It, like the smaller Bankhead Tunnel a few blocks upriver from it, was constructed in Mobile at the shipyards of the Alabama Drydock and Shipbuilding Company (ADDSCO) from 1969-1973. The George Corley Wallace Tunnel, actually two separate tunnels (one for two lanes of travel eastbound, and one for two lanes of travel westbound on Interstate 10), was built in sections and floated to the proper positions, then sunk. Each section was sunk next to the previous section and joined underwater. When all sections were connected, and concrete set into place, they were pumped dry and finished out. The depth of clearance is 40 ft (12.2 m) for the ship channel over the tunnel. This is the same clearance as the older Bankhead Tunnel.
The tunnel was officially opened to traffic on February 9, 1973, after $50 million ($291.8 million in 2020 dollars) was spent to construct it.
