State Audit Clouds Future of Proposed NC Outer Banks Bridge
First proposed more than 50 years ago, the 7-mile link between mainland Currituck County and barrier island communities would provide an alternative to Wright Memorial Bridge, a four-lane causeway to the south that frequently bogs down with visitor traffic, particularly during peak summer months.
Despite having a favorable federal record of decision and many key permits in place, the long-planned Mid-Currituck Bridge to North Carolina’s Outer Banks remains far from becoming a reality according to a June 22 report by the state’s auditing agency.
Using data from the North Carolina Dept. of Transportation, the Office of the State Auditor found that in the years since the Federal Highway Administration approved the seven-mile, two-lane toll bridge across Currituck Sound in 2019, sharp increases in construction costs have more than doubled the project’s original $491-million estimate, with the current cost now estimated at approximately $1.2 billion. The escalation has resulted in a gap of up to $832 million over the original funding plan. Use of a public-private partnership to build the bridge would narrow the gap only slightly, to $702 million.
In addition, updated studies commissioned by NCDOT forecast slower regional economic growth than what was originally expected more than 15 years ago, a trend that would reduce the new bridge’s expected traffic volume by more than 40%, compromising the agency’s toll-backed borrowing capacity. Offsetting the decrease would require substantially higher tolls, a move that would likely further discourage motorists from using the crossing, the audit found.
NCDOT has long sought to improve access to the northernmost section of barrier islands that make up one of the state’s most popular tourist destinations. A new connection between U.S. Route 158 in Currituck County and State Route 12 near Corolla would provide a time-saving alternative to the existing four-lane Wright Brothers Memorial Bridge further south, which regularly becomes congested during peak summer travel months. The new bridge also would provide an additional hurricane evacuation route for the Outer Banks’ full-time residents and visitors.
In the more than 30 years since the Federal Highway Administration announced plans to begin environmental studies, however, the proposal has struggled to sustain momentum amid local opposition and legal challenges. According to the audit, NCDOT has spent $61 million on the project over that period, including nearly $8 million for an aborted 2009 pre-development agreement that would have made the project North Carolina’s first P3 bridge, with a construction team led by Dragados USA, Traylor Bros. and Weeks Marine. Other costs over the years include environmental and engineering studies, consultant and legal fees and right-of-way acquisition.
NCDOT told local officials earlier this year that it considers the Mid-Currituck Bridge not “likely currently financially feasible without additional project funding.” While a P3 remains a possible option for advancing the project, NCDOT’s toll-oversight division, the N.C. Turnpike Authority has yet to settle on a project delivery strategy or identify a development/construction team.
In a response to the audit’s findings included in the report, David Roy, the Turnpike Authority’s director of innovative financing, said that the observations “are consistent with the project studies and events that have taken place over the last 30+ years that the project has been under study.” He added that NCDOT “remains committed to delivering projects requested by local governments and programmed in the State Transportation Improvement Program.”
Absent a path forward, NCDOT says that no construction will take place on the Mid-Currituck Bridge until at least mid-2028. The project’s U.S. Army Corps of Engineers’ Section 404/Section 10 permit, issued in October 2025, is set to expire at the end of 2030. Most other needed state-level permits have been issued, while the outcome of a permit application to the U.S. Coast Guard is pending.
In a June 22 presentation to the Currituck County Board of Commissioners, State Auditor Dave Boliek said the audit, one of a series of fiscal investigations being carried out across the state, is not intended to directly revitalize or undercut the bridge project.
“Our goal is to help move things along, one way or another,” Boliek added.
