Construction Starts for New Alligator River Bridge

News Summary

The construction of the new Alligator River Bridge has begun, replacing the aging Lindsay C. Warren Bridge. Valued at $450 million, this project is supported by NCDOT and is expected to improve safety and travel efficiency by fall 2029. Key features include modern design upgrades and enhancements for hurricane evacuation routes.

Construction Kicks Off for New Alligator River Bridge

The much-anticipated construction of the new Alligator River Bridge has officially commenced, marked by the driving of the first concrete pile. This significant infrastructure project is valued at an astounding $450 million and has received overwhelming support from multiple stakeholders, including the North Carolina Department of Transportation (NCDOT).

Replacing the Aging Lindsay C. Warren Bridge

Strategically located along U.S. 64, the new bridge will replace the aging Lindsay C. Warren Bridge, which has been serving as a vital link between Tyrrell and Dare Counties. This bridge is not just crucial for local travel; it serves as a primary access route to the popular Outer Banks, making it essential for residents and tourists alike.

Modern Features and Important Timeline

The modernized bridge, designed as a fixed-span structure, will be constructed just north of the existing bridge and is expected to be completed and open to traffic by fall 2029. With safety and efficiency as top priorities, the new design aims to bolster hurricane evacuation routes, enhancing the overall travel experience for both residents and visitors alike.

Significant Improvements Over Existing Structure

The current Lindsay C. Warren Bridge measures 2.8 miles in length and was built in 1960. It has been plagued by mechanical failures which necessitate frequent monitoring and repairs. These mechanical issues have resulted in an average 99-mile detour for motorists when the bridge is closed or when it opens for boat traffic.

In stark contrast, the new Alligator River Bridge will feature significant upgrades, including two 12-foot travel lanes complemented by 8-foot breakdown lanes. By elevating the structure to 65 feet above the channel, the need for a moveable section is eliminated, thereby preventing delays.

Addressing Structural Concerns

Officials have deemed the current bridge structurally deficient, yet they reassure the public that it is not unsafe. The existing bridge’s shoulders measure only 1 foot wide and it features a railing height of just 2 feet 10 inches, making the upgrade all the more necessary. Transitioning to a bridge that covers a span of 3.2 miles will not only improve safety but also accommodate bicycle access.

Funding and Environmental Planning

The funding for this critical infrastructure project is bolstered by a $110 million federal grant awarded under the Bipartisan Infrastructure Law, alongside a federal infrastructure grant designated by the U.S. Department of Transportation in January 2023. While this federal grant funding is currently paused, the NCDOT remains optimistic about its reinstatement to continue the project.

Notably, extensive environmental work and planning took place from early 2021 to late 2022. The new bridge’s foundation will rely on hundreds of concrete piles, a design change made to enhance stability, and environmental testing was conducted with the driving of 11 test piles in July 2024.

Future Developments and Local Impact

Demolition of the existing Lindsay C. Warren Bridge is slated to begin in spring 2030 once the new structure opens, marking a new chapter for transportation in the region. The NCDOT has emphasized that this project will enhance safety, stimulate economic development, and improve connectivity between the mainland and the iconic Outer Banks.

As construction progresses, the new Alligator River Bridge is set to redefine not only the landscape but also the accessibility and safety for countless drivers and boaters in this vibrant community.
