The George C. Wallace Tunnel, like the Bankhead Tunnel, emerges on the west end under Royal Street, in downtown Mobile (
see map); however, whereas the Bankhead Tunnel emerges at street level joining into Government Street, the George C. Wallace Tunnel slopes upward to continue Interstate 10 as an elevated highway above the Mobile streets. On the eastern end, over Blakeley Island, the George C. Wallace Tunnel again slopes upward becoming the elevated spans of I-10, which cross
Mobile Bay eastward, along the twin bridges of the curved I-10 Jubilee Parkway. The western approach of the tunnel features a sharp curve which causes lengthy traffic backups in each direction depending on demand, and is part of the impetus to study a replacement for the tunnel. ==Nearby construction==
