I-49 Business

Interstate Business Route 49

Interstate 49 has four designated business loops, all of which are in Missouri and were signed at the same time the route was commissioned in the Show Me State. The American Association of State Highway and Transportation Officials (AASHTO) conditionally approved the routes on October 13, 2011. The business loops for Interstate 49 eliminated those previously posted for U.S. 71.



Active Business Route

Business Loop I-49 in Neosho begins at a rural diamond interchange (Exit 20) with Highway AA southwest of the Neosho city limits. The initial leg of the business route stems east to Missouri Route 59 (old U.S. 71) at McElhany over a locally maintained roadway. Combining with Route 59, Business Loop I-49 leads north past Neosho Hugh Robinson Memorial Airport (EOS) and Neosho Industrial Park (part of which was formerly Fort Crowder) to U.S. 60.

MO 59 turns east alongside U.S. 60 across south Neosho, while Business Loop I-49 briefly combines with U.S. 60 Business (Neosho Boulevard) northward. The U.S. 60 business loop angles northeast to the Neosho city center while Business Loop I-49 remains along old U.S. 71 to the west. Route 86 joins the business route from Harmony Street for the return to Interstate 49 at Exit 27.
The 9.74 mile loop was formally established on December 12, 2012 with all of I-49 in Missouri.

Joplin, Webb City, Cartersville and Carthage

Active Business Route

Traveling 22.53 miles overall, Business Loop I-49 follows old U.S. 71 northwest from Exit 33 to Joplin and Webb City and Route 171 east from Cartersville to I-49 at Carthage. The route was established in place of U.S. 71 Business on December 12, 2012.
Beginning opposite Route 175 (old U.S. 71 south to Route 86 and the Neosho business route), Business Loop I-49 winds northwest along Gateway Drive, a locally maintained roadway, to become Rangeline Road through the city of Joplin. A diverging diamond interchange (DDI) joins Business Loop I-49 with I-44 at Exit 8.

Rangeline Road forms a commercial boulevard northward across the east side of Joplin to Business Loop I-44/Route 66 and Northpark Mall. The former route of U.S. 71 used to have a second business route, which looped west via 32nd Street (Highway FF) and north via Main Street (Business Loop I-44/Route 43) to Downtown Joplin. The original U.S. 71 Business took a stair stepped route back to U.S. 71 from Broadway Street to Zora Street at Oakland Park.

Business Loop I-49 continues north from there into Webb City along Madison Street to Route 171 (5th Street), where the route turns east along an expressway to the freeway along Route 249 bypassing Webb City.

The remainder of Business Loop I-49 overlaps with the freeway on Route 171 east through Cartersville to the Jasper County seat of Carthage. The business route combines with Route 96 ahead of the diamond interchange (Exit 53) with Interstate 49 at Central Avenue. There Route 171 ends and Route 571 begins as I-49/U.S. 71 bypass the city to the west.


Active Business Route

Business Loop I-49 in Nevada forms an L-shaped route west from Exit 101 and north to a wye interchange at Exit 102 B. The 2.93 mile long route follows Austin Boulevard west to U.S. 54 (Centennial Boulevard), which overlaps with Business Loop I-49 west to Osage Boulevard outside Downtown. Osage Boulevard meanders northward and parallels a Missouri & Northern Arkansas (MNA) Railroad Company line to end at Interstate 49 by Atlantic Avenue.

Business Loop I-49 in Nevada was known as Business U.S. 71 until December 12, 2012.
