NCDOT awards nearly $4 million contract to preserve Thomas Rhodes Bridge

READ MORE:

RALEIGH, NC (NEWS RELEASE) -- Department of Transportation Secretary Gene Conti has awarded a contract to preserve the Thomas Rhodes Bridge, which carries U.S. 421 over the Cape Fear River in New Hanover County. The project will entail major preservation work including hydro-demolition of the bridge deck and the placement of a latex modified overlay, replacement of expansion joints, cleaning and painting of the structural steel and various structural concrete repairs.

The $ 3,990,541 contract was awarded to HRI Bridge Company of State College, Pa. Work can begin at any period between March and October 2013 and must be completed 410 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 bridges. In addition, hydro-demolition is safer and faster than traditional demolition methods and minimizes the impact to traffic.

This is one of 22 contracts totaling $67.1 million awarded by Conti in November 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 6.2 percent, or $4.5 million, below NCDOT estimates.
