Purpose and Need
The purpose of the project is to replace the two existing bridges, north and southbound, on US 301 in Orangeburg county over Four Hole Swamp to improve US 301 corridor mobility. The southbound bridge is 26' wide and 246' long and was constructed in 1950. The northbound bridge is 39' wide and 290' long and was constructed in 1970. The southbound bridge is currently restricted to 1 lane due to structural issues. Due to the structural deficiencies, the bridges need to be replaced to maintain operational purposes. The new bridges will be constructed on alignment utilizing a temporary bridge for maintenance of traffic during construction.
