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.

As the road enters the former community of Koerber, and then passes by the site of the former railroad station, US 90 appears to serve as the southern terminus of CR 183 (Kidd Road). However, CR 183 secretly joins US 90 in a concurrency as they both climb a small hill, and shortly descend near a small industrial area. US 90/CR 183 curve slightly to the southeast as they enter Argyle, where CR 183 secretly joins CR 10A, while US 90 briefly curves to the northeast. CR 10A is named Old Highway 90), then removes the name "Old Spanish Trail" from US 90 as it crosses US 90 before both the old and "new" versions of US 90 cross the Walton-Holmes County Line.
