The lone business loop for Interstate 15 in Nevada is the locally maintained route that follows Mesquite Boulevard and Sandhill Boulevard between Exits 120 and 122 in the city of Mesquite. U.S. 91 previously ran along all of Mesquite Boulevard and Sandhill Boulevard north to Hillside Drive; Hillside Drive continued the highway into Arizona by a former airport. With U.S. 91 decommissioned through Nevada in 1973, the alignment through Mesquite was redesignated as an extension of Nevada 170 east to I-15. Nevada 144 replaced Nevada 170 along Mesquite Boulevard and Sandhill Boulevard in 1976. The 2.853 mile route of Nevada 144 was subsequently transferred to local maintenance in 2005.

The diamond interchange at the west end of Business Loop I-15 was rebuilt in 2011-12. The $25 million project converted the exchange into a dumbbell, with roundabouts joining freeway ramps with Falcon Ridge Parkway north and south, and Mesquite Boulevard east. Additionally, Falcon Ridge Parkway was expanded to six overall lanes north to Pioneer Boulevard, and extended south to Leavitt Lane.1
