New Alligator River Bridge Construction Begins

Construction of the new Alligator River Bridge is officially underway, promising improved transport connectivity.

News Summary

The construction of the new Alligator River Bridge has commenced, set to replace the aging Lindsay C. Warren Bridge. This $449.8 million project aims to improve transportation between Tyrrell and Dare counties, with a completion date expected in the fall of 2029. The new design includes a clearance of 65 feet above the waterway and enhanced safety features for vehicles and pedestrians. The project, funded through federal grants and state contributions, will greatly alleviate traffic issues and serve as an essential evacuation route during emergencies.

New Alligator River Bridge Construction Commences

Exciting developments are underway as construction begins on a new bridge over the Alligator River, set to replace the aging Lindsay C. Warren Bridge. This $449.8 million project, contracted to Skanska USA, will enhance transportation between Tyrrell and Dare counties, with an expected completion date in the fall of 2029.

An End to Traffic Woes

The current bridge, which opened its doors in the early 1960s, has served as a vital link for over five decades. Though it replaced a once-active ferry service, the bridge has become a source of frustration for drivers. The swing-span design of the bridge, which stops traffic on U.S. 64 to allow boats to pass, has caused significant delays, requiring ongoing repairs. More than 4,000 boats navigate the channel annually, and the newly designed structure promises a smoother experience for both drivers and mariners alike.

What’s New in the Design?

Set to span 3.2 miles north of the existing bridge, the new Alligator River Bridge will offer a modern design that includes a clearance of 65 feet above the waterway. This significant elevation means that boats can pass underneath without halting traffic—truly a game changer for the region.

Moreover, the bridge will feature two 12-foot travel lanes alongside 8-foot shoulders on both sides, accommodating bicycles and improving safety. With enhanced guardrails rising to 4 feet 6 inches high—compared to the current height of 2 feet 10 inches—pedestrian safety becomes a priority in the new design.

Funding and Project Overview

The N.C. Department of Transportation (NCDOT) has secured a $110 million federal grant as part of the Bipartisan Infrastructure Law, contributing to the project’s overall estimated cost of $286 million. Although initial estimates were around $268 million as of January 2023, this figure has ballooned due to a surge of over 30% in construction prices, largely attributed to challenges posed by the COVID-19 pandemic.

Future Plans and Demolition

The bridge’s importance extends beyond daily commutes; it serves as a critical escape route for residents during hurricane evacuations. Once the new bridge opens in 2029, demolition of the existing Lindsay C. Warren Bridge will start in the spring of 2030. This transition is necessary to complete the infrastructure upgrade and support the increased volume of both vehicle and maritime traffic.

Getting Started

Construction is set to commence in the coming weeks, with Skanska USA starting with the driving of bridge pilings, weather permitting. This phase follows the completion of initial groundwork, which included the installation of eleven test pilings to evaluate the soil for the bridge’s foundation. These pilings will be dismantled as construction progresses.

Long-range Visions

While the new Alligator River Bridge is a significant advancement, long-range plans aim to widen U.S. 64 to four lanes in the future. However, available funding for these plans is limited, making the current project even more pivotal for the well-being and accessibility of the local area.

As the Alligator River Bridge project launches into a new era of infrastructure improvement, locals and visitors alike can look forward to a reliable and efficient route connecting the mainland to the beautiful Outer Banks of North Carolina.
