Warrior River, Lock No. 3 Wall, River Road at University Park, Tuscaloosa, Tuscaloosa County, AL

Significance: The Warrior River lock, dam and quarry sites along the Tuscaloosa riverfront constitute the best surviving remains of an extensive system of locks and dams that opened river transportation for the Birmingham District by creating the longest, channelized waterway in the world at time of its construction. These locks mark the efforts to create a commercial waterway through the Birmingham District to link it to southern ports and international markets. The massive engineering work represents the union of federal and commercial interests.
