The N.C. Department of Transportation proposes to replace the Lindsay C. Warren Bridge on U.S. 64 over the Alligator River in Tyrrell and Dare counties. 

The new bridge will replace the existing swing-span bridge with a modern two-lane, fixed-span (does not move), high-rise bridge on a new location, just north of the current bridge. The new bridge will also include two 12-foot travel lanes with 8-foot breakdown lanes.

Built in 1960, the Lindsay C. Warren Bridge, also referred to as Alligator River Bridge, has been rated “structurally deficient.” This does not imply that the 63-year-old bridge is unsafe. It means the bridge is reaching the end of its lifecycle and must be monitored, inspected and maintained on a more frequent basis. The work to maintain the current bridge negatively impacts its ability to provide a reliable connection between Columbia, Manns Harbor, Manteo and the Outer Banks. 

The environmental planning and preliminary design phase to replace the bridge began in early 2021 and finished in late 2022.
