Cultural Resources Survey of the SC-4/302 Bridge Approaches over the South Fork Edisto, Aiken County, South Carolina

"The Department proposes to replace two bridges located on S.C. 4/302. The project corridor is located 1.5 miles south of SC302. The first bridge, ID number SN 024000400200, is situated over the South Fork Edisto River and is located approximately 10 miles east of the city of Aiken. The existing 60l-foot x 28-foot bridge was constructed in 1958, and is a steel continuous stringer type structure. The replacement bridge will be a reinforced concrete flat slab and prestressed concrete Type III beam bridge 600 feet in length and having a 44-foot clear roadway width. The new bridge is to be constructed approximately 45 feet downstream of the existing bridge. The second bridge to be replaced is ID number SN 024000400300, situated over Cedar Creek just east of bridge SN 024000400200. Currently the bridge over Cedar Creek is a concrete tee beam type, originally built in 1932. This replacement bridge will also be constructed approximately 45 feet downstream of the existing overpass. The new bridge will be a modem reinforced concrete flat slab and prestressed concrete Type III bridge with a 44-foot clear roadway width and a length of 120 feet. Both bridges will be supported on cast in place reinforced concrete bent caps with prestressed concrete piles. The improvement also includes a 24-foot approach roadway section in order to accommodate 2 feet of paved shoulder, 8 feet of grassed shoulder, guardrail placement, approach slabs, and surfacing work in order to tie the new construction to the existing roadway. The survey corridor is 1.449 miles in length."
