U.S. Route 90
U.S. Route 90 (US 90) is an east–west United States highway. Despite the "0" in its route number, US 90 never was a full coast-to-coast route; it has always ended at Van Horn, Texas with the exception of a short-lived northward extension to US 62/US 180 near Pine Springs, Texas which lasted less than a year, and the signs on that segment were changed to Texas State Highway 54, traveling from Interstate 10 (I-10) at exit 140A and heading to its northern terminus at US 62/US 180.

The freeway continues east through Spokane's suburban neighborhoods, flanked by a pair of frontage roads that funnel traffic towards local streets at interchanges, and passes the future terminus of the North Spokane Corridor, a major freeway that will carry US 395 when completed. I-90 then enters Spokane Valley near Avista Stadium and the Interstate Fairgrounds. The freeway travels on the north side of the suburban city and intersects SR 27 near the Spokane Valley Mall. I-90 follows the Spokane River and Centennial Trail through Liberty Lake and to the Idaho state line. The freeway then continues across the Spokane River towards Post Falls and Coeur d'Alene.
