NCDOT Details of NC-12 Fix – Quick Facts and Timeline

This information can be found on this page on NCDOT: http://www.ncdot.gov/travel/nc12recovery/

NCDOT has developed a plan to restore normal traffic to NC 12 within one month. This short-term
solution provides time for NCDOT, working in constant collaboration with agency partners and experts
as well as state, local, and federal officials, to develop a comprehensive long-term strategy, consistent with the approved environmental studies.

Repairs along NC 12 are estimated to cost $10 million and will be paid for from Federal Emergency
funds.

Gov. Perdue has directed NCDOT to work closely with all partners to develop a long-term plan as soon as possible.

The plan involves the placement of a temporary, manufactured bridge across the largest breach which is about six miles south of the Bonner Bridge, on Pea Island. The remaining breaches will be filled in.

QUICK FACTS ON TEMPORARY BRIDGE:
– Manufactured by Mabey Bridge
– Estimated cost between $2.5 and $2.7 million
– Will ship from manufacturer in 35 truckloads and be assembled on-site
– Once assembled, will span 650 feet
– NCDOT will drive 60 ft. piles to support the bridge top
– Bridge made of metal, thus is not a permanent solution in a marine environment
– Will support normal car and truck loads and widths, although speed limit will be reduced
– NCDOT has a similar bridge in place on US 52 in Winston-Salem
