RALEIGH – Islanders needing to drive the long way to mainland points west should be aware of a second closing March 14 to 20 of the Alligator River Bridge between Tyrrell and Dare counties.

The closure will allow NCDOT crews to complete major renovation work on the bridge’s swing-span drawbridge.

The bridge will be closed to all vehicle traffic at 12:01 a.m. on Wednesday, March 14, and is expected to reopen by 11:59 p.m. on Tuesday, March 20. The drawbridge will also be closed to boat navigation.

During the closure, crews will complete the electrical and mechanical swing span repairs that were started during the previous bridge closure Jan. 10 to 17.

During the closure, NCDOT will have detour signage and variable message signs in place to guide motorists through the following detour routes:

  • Motorists traveling east from Columbia should use N.C. 94 South to U.S. 264 East to U.S. 64.
  • Motorists traveling west from Dare County to Columbia should use U.S. 264 West to N.C. 94 North to U.S. 64.
  • Motorists traveling to the Outer Banks from areas west of Williamston should use U.S. 17 North to U.S. 158 East.
  • Motorists traveling from the Outer Banks to points west of Williamston should use U.S. 158 West to U.S. 17 South to U.S. 64 West.

No additional bridge closures are expected during the renovation project.

This work is part of an extensive renovation project designed to extend the life of the 58-year-old bridge. The $16.7 million contract was awarded to Flatiron Constructors of Morrisville, NC, back in March 2017.
