History . US 25 was established on November 11, 1926, as part of the original United States Numbered Highway System; it was routed along the Dixie Highway from North Augusta, South Carolina, to Port Huron, Michigan, with two divides (US 25E and US 25W) through Tennessee and Kentucky, with US 25E having also a short section in Virginia. In 1928, one divided section between Richmond and Newport, Kentucky, was removed; US 25 followed the US 25W routing, while US 25E was mostly replaced by US 27. In 1929, US 25 was extended south into Georgia, ending at US 80 near Statesboro, Georgia . In 1933, US 25 was extended north from Port Huron to Port Austin, Michigan. In 1936, US 25 was extended south again to its current terminus at US 17 in Brunswick, Georgia. In 1974, US 25 was eliminated in Ohio and Michigan, establishing its northern terminus on the Clay Wade Bailey Bridge in Covington, Kentucky. Its former alignment was replaced by Interstate 75 between Cincinnati and Detroit, and Interstate 94 between Detroit and Port Huron. M-25 continues as the designation of former US 25 between Port Huron and Port Austin. In 2000, US 25E was rerouted through the Cumberland Gap  Tunnel (opened four years prior), making a direct link between Tennessee and Kentucky, eliminating Virginia's short section. Its old alignment that went through historic Cumberland Gap was handed over to the Cumberland Gap National Historical Park, and the former roadbed through the park restored to an early 19th-century wagon path.
