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.

SR 90's southern terminus is at the center of the town of Rural Retreat at the intersection of Main Street and Baumgardner Avenue. Main Street continues south as SR 749 and Baumgardner Avenue is SR 616 in both directions. The state highway heads north and has an at-grade crossing of Norfolk Southern Railway's Pulaski District. SR 90 leaves the town limits and intersects US 11 (Lee Highway) at Staley Crossroads. The state highway continues to its northern terminus at the southbound ramps of its diamond interchange with I-81. The roadway continues north as SR 680 (Blacklick Road).
