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.
Kentucky Route 90
KY 90 then heads into a south-southeasterly path to the Barren County seat, Glasgow, where it crosses the Veterans Outer Loop (US 68) passes the local Walmart and a local Marquee Cinema, and then has junctions with US Highways 31E and 68 Business, which is co-joined with Kentucky Route 80 in this area. It also has an intersection with US 31E's business loop at the Barren County courthouse. Before leaving the city of Glasgow, KY 90 has an intersection with the Louie B. Nunn Cumberland Parkway at the exit 14 interchange on the southeastern side of the city.
