Description: The town of Rodanthe is on the Outer Banks of North Carolina between the Pamlico Sound and Atlantic Ocean. Heavily traveled by vacationers in the summer season, NC 12 is also the sole land evacuation route for coastal storms. Several times a year, sand and coastal over wash closes the stretch of road known as the “S” curves for days at a time. After years of constant maintenance, NCDOT advertised the Rodanthe “Jug-Handle” Bridge design-build project in 2013 and awarded the project to the Flatiron/RK&K team several years later. Flatiron/RK&K utilized many precast bridge elements and construction techniques to accelerate the construction timeline of the bridge. Precast cylinder piles, beams, deck panels and sheet piles were used extensively throughout the project. Construction of the bridge was done by utilizing an advancing rail system with gantries and cranes perched above the permanent structure and advancing forward as spans were completed. The completed bridge opens to traffic in April 2022
