a four-lane road plus center turn lane that crosses a pair of creeks before expanding to a six-lane divided highway and meeting I-26 at a partial cloverleaf interchange. Just south of that interchange, US 176, US 21, and US 321 meet ramps from the southern terminus of I-77 (Veterans Memorial Freeway) opposite Fish Hatchery Road. The three U.S. Highways reduce to four lanes and cross over CSX's Columbia Subdivision east of the town of Pine Ridge. US 321 continues south toward Gaston and Swansea while US 176 and US 21 head southeast along Charleston Highway, which drops to two lanes. The two U.S. Highways meet I-26 at a partial cloverleaf interchange and briefly parallel the Interstate as they enter Calhoun County, where the highway is known as Old State Road. The highways diverge at Sandy Run, where US 21 heads south on Columbia Road toward Orangeburg and US 176 continues on Old State Road. West of St. Matthews, the U.S. highway runs concurrently with SC 6 between Caw Caw Road and Bridge Street. US 176 intersects US 601 (St. Matthews Road) and crosses over Norfolk Southern's SC Line south of the county seat of Calhoun County. The highway intersects SC 33 (Cameron Road) in the town of Cameron before leaving Calhoun County. Shortly after entering Orangeburg County, US 176 intersects US 301 (Five Chop Road) just west of the latter highway's junction with SC 47. The highway intersects SC 210 (Vance Road) at the crossroads of Providence northwest of the U.S. Highway's diamond interchange with I-95. At Wells, US 176 has a five-way intersection with US 15 (Bass Drive) and SC 45 (Branchdale Highway). The highway meets the eastern end of SC 314 (Bunch Ford Road) west of the town of Holly Hill and SC 310 (Camden Road) just inside the town limits. In the center of town, US 176 has a pair of intersections with SC 453, Eutaw Road and Gardner Boulevard, on either side of a grade crossing of CSX's Charleston Subdivision. US 176 enters Berkeley County by crossing the Dean Swamp, a tributary of the Four Hole Swamp. The U.S. Highway, which is named State Road, intersects SC 27 (Old Gilliard Road) and SC 311 shortly after entering the highway. US 176 heads southeast through a mixture of swamp and forest with occasional farmland before entering the suburban area around Charleston at its junction with US 17
