Future

After the completion of

throughout the 2010s, it is uncertain whether US 78 will be decommissioned west of Birmingham or the old route recommissioned as US 78 upon completion of Interstate 22. If the old route is recommissioned as US 78, parts of I-22 and US 78 would be forced to overlap. A stretch from just west of Hamilton, Alabama to the first exit in Mississippi, as well as a stretch from MS 25 in Fulton, Mississippi to the next exit west of Fulton after crossing the Tennessee-Tombigbee waterway will overlap. The Hamilton area overlap would be due to the old US 78 routing no longer exists west of Hamilton having been upgraded to I-22 from Weston westward into Mississippi. The second overlap would be necessary because the old US 78 no longer exists west of downtown Fulton, Mississippi due to the Tennessee-Tombigbee waterway and no bridge in place to carry US 78 traffic on the former route.
