At least five business routes of Interstate 29 (I-29) are known to exist. These business routes provide access from I-29 to adjacent communities.

Saint Joseph loop

Interstate 29 Business Loop (I-29 BL) is a business loop of I-29 in Saint Joseph, Missouri. It begins at a diamond interchange with exit 44 ( U.S. Route 169 (US 169)), and heads northwest, overlapping that route. After a bridge over a former Chicago, Burlington and Quincy Railroad line (now Burlington Northern and Santa Fe), I-29 BL has an intersection with Pear Street, where it turns straight west. Pear Street ends at the intersections of Easton Road and Garfield Avenue, and I-29 BL moves northwest onto Garfield Avenue, along the northeast side of the same CB&Q line it crossed over when it overlapped US 169. One block away from an intersection with 11th Street across the tracks from the LifeLine Foods factory, northbound I-29 BL moves onto 10th Street, while southbound I-29 BL runs along 9th Street. Both streets have partial interchanges with US 36. Southbound 9th Street has onramps to US 36, while northbound 10th Street has offramps from US 36. Through the more formerly industrious downtown St. Joseph, between Mitchell Avenue and Penn Street, both 9th and 10th streets run on the sides of the Pony Express National Museum. ^[1] The oneway pair ends at Frederick Avenue between Francis and Jules streets, and I-29 BL moves onto Frederick Avenue as it runs northeast. The road turns east at Highly Street near North 25th Street at the Dr. Jacob Geiger House-Maud Wyeth Painter House. Along the way, it passes the Molina Golf Course and runs between the Northwest Missouri Psychiatric Rehabilitation Center and the Glore Psychiatric Museum. I-29 BL encounters US 169, for a second time, as well as the western terminus of Route 6. I-29 BL then turns toward the north, overlapping US 169 (Belt Highway). At Rochester Road, US 169 ends its concurrency and heads northeasterly while I-29 BL continues northward with Belt Highway. Two miles (3.2 km) later, US 59 joins the business loop and Belt Highway. I-29 BL finally ends at exit 53 on I-29, another diamond interchange, and US 59 continues north. ^[2]

Sioux Falls spur

Interstate 29 Downtown (I-29 Dwtn.) is a locally maintained business spur of I-29 in Sioux Falls, South Dakota. It runs east from a SPUI interchange at exit 79 and is overlapped by SD 42 on 12th Street as it crosses a bridge over the Big Sioux River. This section runs through the Emerson section of Sioux Falls, and, after the intersection with South Grange Avenue, it enters the Folsom's Addition neighborhood, where it curves to the northeast and becomes a oneway pair east of Menlo Avenue. From that point, eastbound I-29 Dwtn./SD 42 run on 11th Street, while westbound the two routes run on 10th Street. I-29 Dwtn. finally terminates at SD 115 (North Minnesota Avenue) on the border between Folsom's Addition and Downtown Sioux Falls. Both routes encounter I-229 Dwtn., which turns from its overlap with SD 115 onto SD 42.

Brookings spur

Interstate 29 Business is a Business Spur of I-29 in Brookings, South Dakota. It runs west from a diamond interchange at exit 132 and is overlapped by US 14 on 6th Street.
