U.S. Route 377 is a north–south United States highway. Originally created as a short spur to connect Denton, Texas with Fort Worth, Texas, it has since been extended to Oklahoma and Mexico for a total length of 478 miles (768 km).
The southern terminus is in Del Rio, Texas at an intersection with U.S. Route 90. It goes north of town co-signed with U.S. Route 277 for 20 miles (32 km). After splitting off, it enters Edwards County and Carta Valley. It meets SH 55 at the county seat, Rocksprings, before serving as the western terminus of SH 41. It heads northeast into Kimble County, crossing the county line near Telegraph. At Junction, Texas, it meets both Interstate 10 and US 83. It then continues northeast through London, extreme southeastern Menard County, and Mason County. In Mason County, US 377 passes through Streeter before forming a concurrency with SH 29 near Grit. In Mason, SH 29 splits off to its own alignment while US 377 turns north to join U.S. Route 87.
