R.F.W. Allston Causeway
This causeway was built between January 1845 and November 1846 by Robert Francis Withers Allston, who owned a summer residence on Pawleys Island. Known as Governor Allston's bank, it connected the island to the mainland. Allston was a large property and slave owner in the area, and was governor of South Carolina 1856-58. The causeway and contiguous property remained in the Allston family until 1901.
Marker is at the intersection of Myrtle Avenue and South Causeway Road (South Carolina Road 22-266), on the right when traveling north on Myrtle Avenue.
