The N.C. Department of Transportation has been planning to put a bridge at Rodanthe for some time. N.C. 12 is particularly susceptible to storm water breaches there, and so a bridge looks like the only way to keep the road viable, long-term.
There are two options for the bridge. Option 1: Go straight through Rodanthe, alongside the current route of N.C. 12. A one lane service road would remain in place to serve the private property alongside the highway.
Option 2: Send the new bridge around Rodanthe, into the Pamlico Sound.
