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.
Special routes of U.S. Route 90
The business route was created in 1992 when US 90 was realigned off the route between Beltway 8 and FM 2100. The portion of the business route between I-610 and Beltway 8 remained concurrent with US 90 until the completion of the current US 90 along the Crosby Freeway in January 2011.
