U.S. 17 north
View of U.S. 17 as it departs Interstate 95 (Exit 33) at Pocotaligo. The U.S. highway follows a four-lane divided highway for nine miles between the freeway and Gardens Corner. U.S. 21 overlaps for the latter six miles of the roadway. Photo taken 01/18/04.
Just 1.5 miles east of the split with Interstate 95 is the merge with U.S. 21 south of Yemassee (pop. 807). U.S. 17 Alternate begins here and travels 7.4 miles north with U.S. 21.

Two banks of shield assemblies lie ahead of the U.S. 17 merge with U.S. 21 and split with U.S. 17 Alternate east of Poctotaligo. U.S. 17 Alternate parallels Interstate 95 to the east 24.4 miles between U.S. 17 and the southern terminus of U.S. 15 at Walterboro. The placement of the trailblazer here dates from before the Interstate system as Interstate 95 provides a faster route to the U.S. 15 corridor. U.S. 21 meanwhile parts ways with U.S. 17 Alternate south of Hendersonville for a westerly trek to Ruffin and Orangeburg. Photo taken 08/28/04.
