Alligator River Bridge (Tyrrell #7) US 64


The project will rehabilitate the existing drawbridge on US 64 over the Alligator River in Tyrrell/Dare County.

Latest News and Updates

Monday, April 15: The Alligator River bridge is now open to traffic. NCDOT crews have removed the bridge closure signs on U.S. 64. This morning, they will remove the detour signage on N.C. 94 and U.S. 264.

The bridge reopened at 11:45 p.m. on Sunday, April 14 � about 12 hours later than originally scheduled. The delay was caused by the discovery that one of the key parts used to keep the bridge closed and support the weight of the vehicles broke during repairs. NCDOT worked quickly to secure a replacement part, make the repairs and reopen the bridge..

Project Overview and Purpose

This project will specifically:

  • Swing the bridge open
  • Jack up the bridge and support it on both ends
  • Pull the pivot out of the center
  • Replace the pivot
  • Replace all balance wheels
  • Replace some of the gears and shafts

The Alligator River bridge was built in 1960 and is 14,928 feet in length. The bridge is a drawbridge and opens an average of 500 times each month. Due to the tremendous amount of openings each year, the mechanical components of the bridge are worn. The purpose of this project is to perform rehabilitation work on the components in the hopes of preventing future closures to the bridge.

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.
