KCI provided a safety inspection of the 5.2-mile Virginia Dare Memorial Bridge, the longest structure in North Carolina. The structure connects the Outer Banks via the US Route 64 bypass at Manns Harbor with Roanoke Island. This was NCDOT’s first core element inspection of the 268-span bridge.
With only a short window for completion, we had to develop and implement a strategy to tackle the voluminous amount of field work, extensive data collection and detailed report preparation. The schedule allowed little room for unforeseeable circumstance and conditions.

Spilt into three teams, engineers used specialized equipment to access every component of the bridge, including the three-span main channel crossing. Under newer protocols, engineers observed and documented the size, material consistency and condition of each structural element of the Virginia Dare Bridge, involving nearly 11,000 individual components.
Challenges included weather, sensitive wetlands, maintenance of traffic, equipment failure, a compressed schedule, and data collection strategies utilizing NCDOT’s proprietary data management system called Wearable Inspection Grading Information Network System (WIGINS). The firm completed the inspection and submitted the required report, at 1500 pages, in just 36 days.
