RALEIGH – N.C. Department of Transportation Secretary Gene Conti has awarded a $2.3 million contract for preservation work on seven bridges in Robeson County and one bridge each in Bladen and Cumberland counties.
Work is set to start by May 1, with project completion expected 280 days after construction begins. The work will extend the lifespan of the bridges and minimize the frequency of future maintenance, which will mean less disruption to traffic.
The contract was awarded to Palmetto Infrastructure Inc. of Greenville, S.C.
Four of the nine bridges will be cleaned and pot holes and other deteriorated surface areas patched. A layer of epoxy/aggregate will then be applied to help make the surface more resistant to salt penetration.
The remaining five bridges will undergo more extensive repairs. Workers will remove old deck surfaces with a milling machine followed by hydro-demolition – a process that uses high-pressure water jets to clear away old concrete and rebar corrosion without damage to the underlying steel. A special surface treatment of concrete mixed with latex, known as latex-modified concrete, then will be applied. This makes bridges less susceptible to salt penetration and allows them to reopen to traffic more quickly than a typical concrete application.
Bridges slated for rehabilitation in Robeson County are on:
· N.C. 130 Bypass over Interstate 95 east of Rowland, epoxy overlay;
· Hilly Branch Road over Black Swamp Creek near Lumberton, epoxy overlay;
· East- and west-abound lanes of Andrew Jackson Highway over N.C. 41 South near Lumberton, latex modified concrete;
· Dew Road over Interstate 95 near Raynham, epoxy overlay; and
· North- and south-bound lanes on Interstate 95 over Boyce Road near McDonald, latex-modified concrete.
Slated for rehabilitation in Bladen County is the bridge southbound U.S. 701 over the Cape Fear River near Elizabethtown. An epoxy overlay will be used.
Slated for rehabilitation in Cumberland County is the bridge on Murphy Road over Interstate 95 near Eastover. The latex-modified concrete process will be used.
This is one of 34 contracts totaling $130.8 million awarded by Conti for highway and bridge projects across North Carolina during the past month. NCDOT awarded the contracts to the lowest bidders, as required by state law. The bids received on the projects awarded came in about 1.4 percent, or $118.8 million, below NCDOT estimates.
Since Gov. Bev Perdue took office in January of 2009, NCDOT has awarded 575 highway contracts totaling $4.1 billion to ensure that all North Carolinians have access to jobs and educational opportunities.
