Four business routes of Interstate 49 (I-49) exist, all of them within the state of Missouri. All four were once business routes of US-71, and were converted to business routes of I-49 on December 12, 2012, when that highway was designated in Missouri.

Neosho business loop
Interstate 49 Business is a business route of Interstate 49. It begins two miles (3.2 km) northwest of Neosho, Missouri at I-49/US-71 and Route 86 and ends south of the city at I-49/US-71 and Route AA. Part of the highway overlaps Highway 86; another part overlaps Route 59. The road is a previous alignment of US-71, which was realigned west of Neosho as a freeway, and was eventually upgraded to I-49.
Route 175, which ends near the north end of Business US 71 was once also labeled Business US 71, joining this route with Business US 71 in Joplin, making this an even longer route.
Joplin business loop
Business Loop 49 is an alternate alignment of I-49/US-71 which begins at a junction of I-49, U.S. Route 71, Route 96, Route 171, and Route 571 in Carthage, Missouri. Its southern end is at the junction of I-49/US-71 and Route 175 about midway between Joplin and Neosho at Tipton Ford.
This particular section of Business I-49 is a relatively long one, and begins its existence as a freeway, finally becoming a non-freeway divided highway at Webb City. It is a major boulevard in Joplin where it is known as Range Line Road. At Interstate 44, its interchange was reconstructed from a cloverleaf design to a diverging diamond interchange, opening on July 19, 2013. Business I-49 continues south until it ends at I-49/US-71.
The road was an earlier alignment of US-71 until the newer freeway that eventually became I-49 was built to carry the road to the east of Joplin. At one point, Route 175 had been labeled Business US-71, and the road continued south as Business 71 in Neosho.
