Business Loop I-15 - Mesquite

The lone business route for I-15 in Nevada loops 3.5 miles through Mesquite via Mesquite and Sandhill Boulevards from Exit 120 east to Exit 122. The loop was previously a part of SR 141 and mostly follows old U.S. 91.

SR 144 was decommissioned in 2005, but signage for the business route remains. With local maintenance, it is unclear if the business route will continue to be signed.
