U.S. 93 Business follows the former route of U.S. 93 through central Missoula between Reserve Street and Interstate 90. The route overlaps with U.S. 12 (Brooks Street) 1.7 miles northeast from Reserve Street to Stephens Avenue. Stephens Avenue and Orange Street continue the route north 2.3 miles through western reaches of Downtown to Exit 104 of I-90.
The route of U.S. 93 in 1968 follows what is now U.S. 93 Business from U.S. 12 to Broadway (Business Loop I-90). U.S. 93 turned onto former U.S. 10 west alongside Montana Highway 200.
