A joint-motion filed with the U.S. Fourth Circuit Court of Appeals says the North Carolina Department of Transportation, Defenders of Wildlife and the Southern Environmental Law Center "have been engaged in active settlement negotiations since August 2014 in an effort to resolve the issues."
It goes on to say that "substantial progress" towards settlement has been made, but "the assistance of a mediator will be helpful,
perhaps essential, in resolving the remaining issues and achieving a settlement of both cases."
The Bonner Bridge is the only highway link to and from Hatteras Island on North Carolina's Outer Banks.
