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.[2] The entrances were designed in the Art Deco style that was popular during the time of construction.[4] It was completed in 1940 at a cost of $4 million and opened to the public on February 20, 1941.[1][4] 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.[1]
The tunnel was designed by Oliver Fowlkes and construction directed by Wayne Palmer of Mobile. Only passenger cars and pickup trucks are still allowed to travel through the tunnel, as it is very narrow. Large trucks can use the George Wallace Tunnel on Interstate 10 a few blocks to the south. However, trucks with hazardous cargo must use the Cochrane–Africatown USA Bridge (U.S. 90/U.S. 98 Truck)[1] a few miles to the north.
Filming location
The tunnel was the location of a scene in the 1977 blockbuster Close Encounters of the Third Kind by director Steven Spielberg, a film which was primarily filmed in the Mobile area. In this particular scene Roy Neary, played by Richard Dreyfuss, drives through the tunnel as he chases UFOs.[5]
The tunnel was later featured during a motorcycle chase scene in the 1991 film Stone Cold, starring Brian Bosworth.[5]
