U.S. Route 378 (US 378) is a spur of US 78 in the U.S. states of Georgia and South Carolina. The U.S. Highway runs 234.30 miles (377.07 km) from US 78, Georgia State Route 10 (SR 10), SR 17, and SR 47 in Washington, Georgia, east to US 501 Business in Conway, South Carolina. US 378 connects the Central Savannah River Area in both states with the Midlands and Pee Dee regions of South Carolina. The U.S. Highway's western portion, which connects Washington and Lincolnton in Georgia and McCormick, Saluda, and Lexington in South Carolina, is mainly a rural highway. US 378 is a major suburban and urban highway through Lexington and South Carolina's state capital, Columbia. The highway has a lengthy concurrency with US 76 between Columbia and Sumter and serves as a major route between the Midlands and the Myrtle Beach area, between which the highway has a business route through Lake City.
