Business Loop I-80 - Winnemucca

This business route follows old U.S. 40 along Winnemucca Boulevard for 7.5 miles. The western part of this route is cosigned with SR 289 as it parallels I-80 closely from Exit 173 to Exit 176, where U.S. 95 departs the freeway for Downtown Winnemucca via Business Loop I-80. U.S. 95 turns northwest along Melarkey Street while SR 289 remains along Winnemucca Boulevard to Exit 178. Business Loop I-80 turns just prior to that interchange and overlaps with SR 794 by the Humboldt County Fairgrounds to end at Exit 180.
