of the city limits at Wright's Crossing. The highways cross the Soap Creek branch of the Savannah River reservoir known as Clarks Hill Lake in Georgia and Lake Strom Thurmond in South Carolina. South Carolina State line to Saluda US 378 and SR 43 meet the eastern end of SR 220 just west of Elijah Clark State Park. SR 43 reaches its northern terminus at the state line at the thalweg of the Savannah River in the center of the lake crossing. US 378 enters Sumter National Forest and crosses the Little River branch of the lake, on the east side of which is Baker Creek State Park. The highway continues to the town of McCormick, through which the highway follows Gold Street. US 378 intersects SC 28 (Mine Street) on the west side of downtown; US 221 leaves its concurrency with SC 28 coming from Augusta and joins US 378 through the downtown area. The U.S. Highways have a grade crossing of CSX's McCormick Subdivision and diverge on the east side of town, with US 221 heading northeast as Greenwood Highway. US 378 leaves McCormick, passes McCormick County Airport, and forms the southern boundary of Sumter National Forest east of the town. East of Liberty Hill, where the highway fully enters the national forest, the road crosses the McCormick–Edgefield county line. US 378 again forms the southern boundary of Sumter National Forest from its intersection with SC 67 (Callison Highway). The highway also intersects US 25 and SC 430 (Meeting Street Road) while passing along the northern tier of Edgefield County. US 378 leaves the national forest shortly after entering Saluda County. The highway enters the town of Saluda along Church Street and intersects Main Street, which carries US 178, SC 39, and SC 121. Two blocks to the east, US 378 turns north onto Jennings Street, then turns east on Travis Avenue at its junction with SC 194, which heads north on Jennings Street, and US 178 Connector, which heads west on Travis Avenue to connect with US 178. Saluda to Sumter US 378 crosses the Little Saluda River and leaves Saluda along Columbia Highway. After crossing Clouds Creek, the highway meets SC 391 (Prosperity Highway/Summerland Highway) at a roundabout and enters Lexington County. East of the Hollow Creek and Horse Creek branches of Lake Murray, US 378 expands to a four-lane road with center turn lane. The
