title: U.S. Route 90
context: U.S. Route90 (US 90) is an east–west United States highway. Despite the "0" in its route number, US90 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 US62/US180 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 US62/US180.
question: Where does U.S. Route 90 end?
answers: US62/US180
