Good Morning Mobile !!! Have a Wonderful Tuesday Friends !! Men launch one of the tubes that make up the Bankhead Tunnel, 1940. The tube would be floated down river and then sunk into place. The tunnel 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. The entrances were designed in the Art Deco style that was popular during the time of construction.It was completed in 1940 at a cost of $4 million and opened to the public on February 20, 1941. A toll fee was charged at the east side, from 1941 to the mid-1970s, when the toll plaza was dismantled.The tube carries two lanes of travel, and no pedestrian or non-motorized vehicular traffic is permitted
