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.
Nevada State Route 290
State Route 290 begins at an intersection with US 95 approximately north of Winnemucca near the Santa Rosa Range. From the junction, the highway heads northeasterly through a valley known as Paradise Valley while paralleling Martin Creek, a fork of the Little Humboldt River. The road turns more northerly after about as it heads into the town of Paradise Valley. Once inside the town, SR 290 turns east on Bridge Street to come to its northern terminus on a small bridge over Big Cottonwood Creek.
