More Outer Banks bridge news. Construction on a permanent Pea Hill bridge has begun on Hatteras Island at the Outer Banks to replace the temporary bridge on Highway 12. The new bridge is a 2.1 mile long bridge that will cost $79.7 million. It will be built next to the temporary bridge that was quickly built just after Hurricane Irene in 2011 that cut the new inlet. Traffic will be affected with planned detours. The plan is to complete the bridge by spring of 2016.
