RALEIGH, NC (NEWS RELEASE) -- Department of Transportation Secretary Gene Conti has awarded a $4.6 million contract to American Bridge Co. of Coraopolis, PA, to preserve the bridge over Snows Cut on US 421 in Carolina Beach.
Work can begin as early as July 1 and is scheduled to be completed within 390 days after the start date.
This bridge will be rehabilitated using a new resurfacing technique called hydro-demolition. During this resurfacing process, the deteriorated concrete on the bridge deck will be removed in part using high-pressured water, and the bridge will be resurfaced using high-strength concrete.
Hydro-demolition is more precise than traditional pavement removal with a jackhammer, and it reduces the potential for damage to the bridge. In addition, hydro-demolition is safer and faster than traditional demolition methods and minimizes the impact to traffic.
In addition to hydro-demolition, the contract also includes painting of structural steel and repairs to substructure concrete.
This is one of 30 contracts totaling $109.3 million recently awarded by Conti for highway and bridge projects across North Carolina. NCDOT awarded the contracts to the lowest bidders, as required by state law. The bids received on the projects awarded came in about 3.9 percent, or $4.4 million, below NCDOT estimates.
