News Summary
The replacement of the Lindsay C. Warren Bridge in North Carolina has officially begun, aiming to enhance safety, traffic flow, and hurricane evacuation efforts. The existing bridge, which has been deemed structurally deficient, will be replaced with a modern fixed-span design that will improve both vehicle and marine traffic. With construction awarded to Skanska USA for $450 million, the project is expected to be completed by 2029, significantly improving emergency evacuation routes and local infrastructure.
Lindsay C. Warren Bridge Replacement Project Underway in North Carolina
Exciting news for residents and visitors of North Carolina—the much-anticipated replacement of the Lindsay C. Warren Bridge has officially begun. This significant infrastructure project aims to enhance safety, improve traffic flow, and bolster hurricane evacuation efforts. The 2.8-mile-long existing swing-span bridge, initially opened in 1960, has been marked as “structurally deficient” and is in urgent need of replacement.
Major Steps Underway
On February 18, construction crews drove the first piles for the new bridge into the ground, marking a critical milestone in the development process. The North Carolina Department of Transportation (NCDOT) has awarded the project to Skanska USA with a contract valued at a whopping $450 million.
The upcoming structure will stretch an impressive 3.2 miles, transitioning from the outdated swing bridge to a more modern fixed-span design over the Alligator River, as part of U.S. 64. With an expected completion date set for 2028, traffic are anticipated to start flowing on the new bridge by Fall 2029. The demolition of the old bridge is slated for Spring 2030.
Key Features of the New Bridge
Boasting a range of modern features, the new bridge will include:
- Two 12-foot travel lanes
- 8-foot breakdown lanes
- 65 feet of vertical clearance from the channel
- 4.5-foot safety railings
This new design aims not only to elevate safety standards but also to support a smoother flow of both vehicle and marine traffic, benefiting over 4,000 boats that traverse the waterway annually.
Hurricane Preparedness and Traffic Improvements
One of the most pressing reasons for the new bridge’s construction is its enhanced hurricane evacuation capabilities. As one of only two key highway corridors linking the Outer Banks to the mainland, the bridge plays an essential role in providing safe passage during emergency weather events. Historically, mechanical failures of the swing bridge have forced motorists to endure a frustrating 99-mile detour, showcasing the urgent need for a reliable crossing.
Between 2017 and 2021, the existing bridge faced closures averaging five times a year, with varying durations of downtime. In 2018 alone, the bridge and the waterway were closed on nine occasions, wreaking havoc on travel plans.
Funding and Environmental Considerations
The project is benefiting from a partial funding boost through a $110 million grant from the Federal Highway Administration under the 2021 Bipartisan Infrastructure Law. Preliminary design work began in early 2021 and wrapped up in late 2022, with final design efforts concluding in winter 2023. In mid-2024, test piles were driven in order to assess riverbed conditions, which will inform ongoing construction plans.
A Vision for the Future
The new bridge will feature a grade-separated design that incorporates redundant precast, prestressed concrete girders and composite concrete decks, ensuring long-term durability and safety. The fixed-height span will provide 65 feet of vertical clearance and 140 feet of horizontal clearance in the main channel, greatly improving river traffic movement.
As the Lindsay C. Warren Bridge replacement progresses, residents can look forward to a safer, more efficient route that not only meets the demands of today’s traffic but also stands resilient against the challenges of natural disasters. With this project, North Carolina is moving toward a brighter and more secure infrastructure future.
