Bonner Bridge Projects


The Bonner Bridge Replacement Project will replace the existing bridge over Oregon Inlet and provide for the long-term retention of N.C. 12 between Oregon Inlet and Rodanthe. The Herbert C. Bonner Bridge, located in Dare County, opened in 1963 and provides the only highway connection between Hatteras Island and mainland North Carolina.

Latest News and Updates

Following a settlement agreement approved in June 2015, lawsuits were officially dropped Aug. 14, 2015, allowing NCDOT to proceed with the replacement of the Herbert C. Bonner Bridge over the Oregon Inlet with a bridge parallel to the existing bridge. NCDOT will also study long-term options for N.C. 12 south of the Bonner Bridge. A study must be completed within a year and a half of lawsuit dismissals.


NCDOT is currently involved with a number of legal actions initiated by national organizations. The documents below detail specific events regarding those actions.

Project Background and Purpose

The Bonner Bridge Replacement Project will:

  • Provide a new, reliable way for residents, tourists and businesses to travel from Bodie Island over Oregon Inlet to Hatteras Island prior to the end of the Bonner Bridge’s service life;
  • Replace the bridge with a design that serves navigation needs, while also allowing natural channel movement and reducing future dredging needs; and
  • Provide a new bridge that shoreline movement will not endanger through 2050.

NCDOT examined a total of eight detailed study alternatives within two corridors before selecting a preferred alternative in 2010. This alternative is detailed in the Record of Decision.

The selected alternative breaks the project into phases:

  • Phase I includes building the new bridge just west of where the Bonner Bridge currently stands.
  • The exact plan for implementing future phases will be determined, based on the department’s active coastal monitoring program. It helps NCDOT decide where and when to make improvements to N.C. 12 from the south end of the Bonner Bridge to Rodanthe. Any of the alternatives (beach nourishment, road relocation and bridging) previously studied as part of the original environmental analysis could be considered for future phases.
  • Phase II of the project is currently under way and includes implementing permanent solutions for the two breaches caused by Hurricane Irene in 2011.

Resources for Local Property Owners

In many cases, it is inevitable that a certain amount of private property must be acquired. The displacement of homes and businesses is minimized to the extent practicable. The following brochures will answer questions about this process.
