Business Loop I-90 - Spokane Valley

AASHTO approved this non-state maintained business loop on May 5, 2013. Continuing along portions of historic U.S. 10 east from the former Spokane business route, the Spokane Valley Business Loop for I-90 extends east from Exit 285. Business Loop I-90 travels along the Valley Couplet of Appleway Boulevard east and Sprague Avenue west between I-90 and University Road. The Valley Couplet was completed in 2000. Construction converted East Sprague Avenue from two-way traffic into a four-lane westbound roadway, complementing the new four-lane eastbound Appleway Boulevard.

East from University Road, Business Loop I-90 carries two-way traffic along East Sprague Avenue, the former alignment of U.S. 10, before returning to I-90 by way of Appleway Avenue east to Barker Road north. The route is approximately 8.21 miles long. It ends at Exit 293.

Business Loop I-90 guide signs are posted on both I-90 east at Exit 285 and I-90 west at Exit 293 for the Spokane Valley business route as of 2015.
