Business Loop I-94 - Fargo and Moorhead

Cosigned with U.S. 10 on the western half and formerly Minnesota Trunk Highway 231 on the eastern half, this 12.6 mile long route joins Downtown Fargo with the Moorhead city center and Bonanzaville USA in West Fargo. The business route emerges from I-94 at a trumpet interchange (Exit 343) on the outskirts of West Fargo and follows U.S. 10 (Main Avenue). Main Avenue also represents former alignments of U.S. 52 and U.S. 10S. The route through West Fargo was redesigned from a industrial style arterial with frontage roads to a landscaped boulevard in stages from 2009 to 2016.

East into the city of Fargo, Business Loop I-94/U.S. 10 expand into a six-lane divided arterial leading to and from I-29/U.S. 81. Differing from the retail strip along 13th Avenue to the south, this stretch of Main Avenue is more industrial with machine shops and hardware stores more prevalent than restaurants and other retail, though some of those front the route as well.

The Veterans Memorial Bridge spans the Red River into Moorhead, Minnesota, with Business Loop I-94/U.S. 10 remaining on Main Avenue to U.S. 75 (8th Street) in Downtown. U.S. 10 branches north from there with U.S. 75 en route to Dilworth while Business Loop I-94 turns southeast toward Interstate 94 along SE Main Avenue. The SE Main Avenue section used to be Minnesota Trunk Highway 231, which was turned back to the city during the 1990s.

The lone business route for Minnesota previously ended at a folded diamond interchange (Exit 2) with CSAH 52. Construction in 2010 relocated the route along a dogleg using 24th Avenue S and the 34th Street S extension to a new interchange (Exit 2) with I-94. The former exchange with Main Avenue SE and CSAH 52 was slated for removal, but restored as a half diamond interchange in 2011 at the urging of local businesses. Field verified in 2015, one benefit of the relocation was the installation of new signs for what was otherwise a poorly signed route leading north from I-94.
