Q. The Snow’s Cut Bridge cement surface appears to be in almost perfect shape. Why are we spending $4.6 million dollars to replace it?

A. The Snow’s Cut Bridge may not be as sound as it appears. The N.C. Department of Transportation is spending $4.6 million to preserve and rehabilitate the existing structure. The concrete deck of the bridge is rated a four out of 10, which is poor, DOT bridge program manager Amanda Glynn said. The department will be resurfacing the deck, cleaning and painting the steel beams, lifting the spans and replacing the bearings, and making structural steel and concrete repairs, she said.

“With the funding levels for transportation infrastructure dipping lower and lower, it is important that we take all steps possible to protect and preserve what we have in place because, financially, complete replacement is not something that can occur quickly,” she said. “The Department found the preservation of the Snow’s Cut Bridge, a vital link in our transportation system, to be a prudent use of taxpayer dollars.

“There are many small cracks in the deck which allow chlorides access to the steel reinforcing. Once this reinforcing is exposed to salt, it corrodes and expands, thus breaking the concrete around it and causing potholes to form in the deck,” she said. “The method of concrete removal for this project, hydro-demolition, uses 17,000 psi (per square inch) water jets to remove all deteriorated concrete. If the reinforcing steel is corroded, it will be exposed and cleaned during this process. The Latex Modified Concrete, which will replace the existing deck, is stronger and denser than traditional concrete. This will help to protect the steel from future salt intrusion.”
