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.
U.S. Bicycle Route 90
U.S. Bicycle Route 90 (USBR 90) is an east-west U.S. Bicycle Route in Arizona and Florida. The American Association of State Highway and Transportation Officials (AASHTO) ultimately plans to extend the route to San Diego, California from its current eastern terminus on the Atlantic Coast south of Jacksonville, Florida. Route 90 was established in November 2014 with the official designation of the Florida section. Its section through Arizona was approved in September 2015.
