Business Loop I-94 stems north from Exit 23 along Red Arrow Highway (old U.S. 12) to the village of Shoreham. The trunk highway straddles coastal areas of Lake Michigan northeast along Lakeshore Drive into the city of St. Joseph, where it connects with Main Street and M-63 through Downtown.

The couplet of Ship Street east and Port Street west lead Business Loop I-94 away from M-63 (Main Street) to Wayne Street across Morrison Channel and Radio Island. The bridge across the St. Joseph River brings Business Loop I-94 into the city of Benton Harbor. Main Street takes the route east through Downtown, one block north of City Hall. M-139 used to overlap with the business loop between Paw Paw Avenue and Martin Luther King Drive. The trunk highway now travels south from Main Street only.

Business loop I-94 transitions into a freeway east from Urbandale Avenue. The highway concludes a 10.85 mile long route (Bessert, 2026) at a trumpet interchange (Exit 33) with I-94 at Benton Heights.
