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.

Near Frenchman Coulee and the Gorge Amphitheater, I-90 turns northeast towards George, where it intersects SR 281 and SR 283, providing access to Quincy and Ephrata, respectively. The freeway continues due east across rural Grant County, paralleled by a pair of frontage roads, past several sand dunes, state recreational areas, and the Potholes Reservoir. I-90 reaches Moses Lake by crossing the eponymous lake's western arm and intersecting SR 171, which serves as the city's main street. The freeway then crosses the Pelican Horn and intersects SR 17 before leaving the city, regaining its frontage roads as it continues east across rural Adams County by following several coulees. I-90 intersects the SR 21 east of the Schrag rest area and continues towards Ritzville, where a long concurrency with US 395 begins. The two highways intersect SR 261 and travel northeast along the BNSF railroad, which carries Amtrak's "Empire Builder" trains, to Sprague Lake in Lincoln County. In Sprague, I-90 intersects SR 23 just south of its junction with SR 231. From Sprague, the freeway passes the Fishtrap Recreation Area and crosses into Spokane County, where it alternates between interchanges with SR 904 and SR 902, which form loops serving Medical Lake and Cheney, respectively.
