NCDOT Awards $4.6 Million Contract to Rehab Snow's Cut Bridge

A project to rehabilitate Snow's Cut Bridge onto Pleasure Island could start in July. The North Carolina Department of Transportation recently awarded a contract to resurface the over 50 year old structure and make other improvements.

CAROLINA BEACH - Snow's Cut Bridge leading onto Pleasure Island turned 50 years old in 2011. North Carolina Department of Transportation Secretary Gene Conti announced Tuesday June 5th, NCDOT has awarded a $4.6 million contract to American Bridge Co. of Coraopolis, Pa. to preserve the bridge over Snows Cut on U.S. 421 in Carolina Beach. The bridge was built in the 1960's and needs attention to areas weathered by the elements over the decades.
Work could begin as early as July 1st and is scheduled for completion in 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-pressure 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.
Before the rehab project begins sometime after July, a separate project will be completed to install guardrails on both sides of the approaches onto and off of Pleasure Island.
 In recent years vehicles have driven off the road just before the bridge, rolling down a steep hill.
Amanda T. Glynn, P.E. - Division Bridge Program Manager for NCDOT  Division 3 - explained earlier this year that hydro-demolition involves using a machine jetting water under high pressure at the road surface to remove typically one to one and a half inches of loose or deteriorated concrete. Sometimes there are deeper areas depending on the condition of the road surface which varies from one area to the next.
After that, a latex modified concrete will be put down to protect the underlying concrete and superstructure from salt intrusion.
During the project travel lanes will be restricted at times.
Estimates earlier this year were from the start date through- October 15: Monday through Thursday 7:00 am - 9:00 am and 4:00 pm - 6:00 pm. 7:00 am Friday though 6:00 pm Sunday. From October 16 - February 28: 7:00 am Friday though 6:00 pm Sunday. Those hours could be adjusted.
Glynn said the lane restriction schedule will allow the contractor to work during daylight hours when temperatures will be more favorable for laying down the latex concrete and painting sections of the bridge.
In addition to hydro-demolition, the contract also includes painting of structural steel and repairs to substructure concrete.
NCDOT hopes that the time restrictions will allow the contractor to complete the project with as little disruption as possible to traffic during the day and to residents living near the bridge at night."
Built in 1961, Snow’s Cut Bridge is the only bridge serving Carolina Beach, Kure Beach and Fort Fisher on Pleasure Island. It receives periodic maintenance and a full inspection every two years.
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.
Since Gov. Perdue took office in January of 2009, NCDOT has awarded 631 highway contracts totaling $4.3 billion to ensure that all North Carolinians have access to jobs and educational opportunities.
Gov. Bev Perdue’s proposed budget continues to support enhancing or expanding our transportation infrastructure.  In doing so, Gov. Perdue continues to support immediate jobs in the construction sector and the goal of ensuring that our transportation network facilitates access to jobs, education and healthcare for the future.
