"First Pile Driven for Alligator River Bridge Replacement"
COLUMBIA, N.C. – The first concrete pile in a $450 million project to replace the Lindsay C. Warren Bridge—commonly referred to as the “Alligator River Bridge”—on U.S. Highway 64 was driven into the bed of the Alligator River between Tyrrell County and Dare County in the early evening of Tuesday, February 17, 2025. A video of the first bridge pile being driven can be viewed by clicking here.
The bridge pile is one of hundreds to be used as a foundation for the new bridge, which will replace the aging swing-span drawbridge with a modern, two-lane fixed-span bridge just north of the current one. The new bridge is expected to open to traffic in the fall of 2029.
The current bridge, completed in 1960, is the main route to access the Outer Banks from the west, and a critical hurricane evacuation route. The aging swing span is maintained regularly but is prone to occasional mechanical failures which force motorists onto a 99-mile detour.
The new bridge will also improve river traffic, as more than 4,000 boats pass through the swing span each year. For more information, please contact Tim Hass at tdhass@ncdot.gov or 252-423-5109. For further project details from NCDOT, please click here.

"Work to Begin Soon on Alligator River Bridge Replacement"
Contract awarded; new fixed-span bridge to open in 2029
COLUMBIA, N.C. – Work will soon begin on a replacement for the Lindsay C. Warren (Alligator River) Bridge on U.S. 64 in Tyrrell and Dare counties, under a contract approved today (January 8, 2025) by the N.C. Board of Transportation.
The $450 million contract, awarded to Skanska USA, will replace the 65-year-old swing-span bridge with a modern, two-lane fixed-span bridge just north of the current one.
Funding is aided by a $110 million grant from the Federal Highway Administration under the Bipartisan Infrastructure Law passed in 2021.
Workers from Skanska will begin driving bridge pilings in the next several weeks, weather permitting, and begin other activities such as clearing soon thereafter. Under terms of the contract, the new bridge will open to traffic in the fall of 2029, with demolition of the current bridge to begin in the spring of 2030.

July 23, 2024 Update from NCDOT:
"Alligator River Bridge Test Pile Project Completed"
COLUMBIA, N.C. – A test pile project in the Alligator River between Tyrrell and Dare counties was completed earlier this month, with 11 large concrete test piles driven into the riverbed at various depths.
The test piles, large posts that are typically used as a foundation for a structure such as a bridge, will help engineers learn about soil layers and depths and soil consistency in the riverbed as they design a replacement for the 64-year-old Alligator River Bridge on U.S. 64.
“The soil samples and field data we collected during the test pile project will help us make revisions that determine the final construction design of the bridge structure”, said N.C. Department of Transportation Resident Engineer Pablo Hernandez.
The test piles will be removed once the bridge construction project is underway.
The new Alligator River bridge will replace the existing swing-span bridge with a modern two-lane, fixed-span, high-rise bridge on a new location just north of the current bridge. The new bridge will include two 12-foot travel lanes with 8-foot shoulders.
Construction on the project is expected to begin in late 2024 or early 2025.
COLUMBIA, N.C. – N.C. Department of Transportation contractors will soon begin driving as many as 18 concrete test piles into the bed of the Alligator River, an important step in the project to replace the Lindsay C. Warren (Alligator River) Bridge on U.S. 64 between Tyrrell and Dare counties.
Skanska USA will be overseeing the test pile project, which will guide design and construction engineers in deciding the best means and methods of constructing the new bridge and will help them complete environmental reviews and construction plans. Piles are heavy posts driven into the ground as a foundation for a structure such as a bridge.
The new bridge will replace the existing 64-year-old swing-span bridge with a modern two-lane, fixed-span, high-rise bridge on a new location, just north of the current bridge. The new bridge will include two 12-foot travel lanes with 8-foot breakdown lanes.
Construction on the new bridge is expected to begin in late 2024 or early 2025.
