NEW BERN BYPASS

To alleviate congestion and offer tourists easier access to their destinations, the North Carolina Department of Transportation decided to reroute U.S. Route 17 out of the historic town of New Bern, North Carolina, and build a new Neuse River Bridge to replace the deteriorating timber and steel crossing that had stood since the 1940s. The new bridge is a 70 ft (21 m) high, 10,000 ft (0.8 km) long steel girder crossing that includes seven ramps and three loop interchanges. Among the toughest challenges was designing and constructing ramps that needed to span over the water to avoid another historic town. The main crossing features multishaft hammerhead bents supported by drilled shafts ranging in size from 30 in. to 72 in. (762 m to 1,829 mm), and steel casing and bentonite slurry walls that protect the bottoms of the shafts from hydrostatic pressure.
