Business Loop I-90 forms an L-shaped route south from Interstate 90 to the city of Buffalo. The north-south leg overlaps with Business Loop I-25 & U.S. 87 Business along Main Street, from Exit 56A south to U.S. 16 (Hart Street). The east-west leg overlaps with U.S. 16 along Hart Street back to I-90 at Exit 58. An array of traveler services line the segment along Hart Street, while the cosigned section with Business Loop I-25 serves the Johnson County Fairgrounds.

The overlap between Business Loops I-25 and 90 represent one of a handful of such combinations in the Interstate system. Business Loops I-15 and 84 combine through both Brigham City and again at Tremonton, Utah. Business Loop I-15 also runs concurrently with Business Loop I-90 through Butte, Montana. Business Loops I-69 and 94 combine through Port Huron, Michigan.
