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.
Business routes of Interstate 90
Interstate 90 Business was a business loop of Interstate 90 in Plankinton. It ran from a diamond interchange at exit 308 north along Aurora CR 35 (386th Avenue/South Main Street) until the intersection with Aurora CR 34 (Old Highway 16). Unlike in White Lake, however, this business route turned right along Old Highway 16 and followed it until the intersection of US 281, where it turned south, overlapping that route until the another diamond interchange with I-90 at exit 310, where it finally terminated.
