Cape Romain was hired by Cox Industries in the summer of 2013 to design and construct two vehicular bridges, for access onto Hall’s Island. The two existing RR trestles were structurally deficient, and would not allow proper access to the island. Demolition and disposal of these existing structures were included in Cape Romain’s contract. Cape Romain assisting in acquiring permits, as well as approvals from USCG, DHEC and Beaufort County. PDA index piles were driven at each site to verify pile capacities. The two bridges were then constructed simultaneously to shorten the overall contract duration. The 90ft bridge was constructed from land via the existing causeway. The 360ft bridge was constructed from barges. Both bridges consisted of 14-inch pre stress concrete piles, poured in place pile caps, and a cored slab deck. DCI concrete was utilized in all concrete members, to give enhanced life span to the bridges.
