Outcomes
  • Reduced travel times for 10,000 travelers each day
  • Increased capacity relieves traffic congestion on a key coastal route
  • Separated opposing traffic lanes reduce the risk of collision.

The North Carolina Department of Transportation (NCDOT) is investing in significant improvements to a 16-mile stretch of U.S. Route 17 to meet growing transportation needs, reduce travel times, and improve traffic safety. A new, four-lane, divided expressway will connect New Bern and Jacksonville, bypassing Belgrade, Maysville, and Pollocksville in the eastern part of the state. This portion of highway is a busy summer beach route, with an average daily traffic count of 10,000 vehicles. It also connects regional military bases and is a vital hurricane evacuation route for coastal communities.

On the existing roadway, vehicles often must slow to a crawl on two lanes that pass through small towns. The U.S. 17 bypass project will relieve congestion by doubling capacity and significantly reduce the risk of collision by separating opposing travel lanes. Gannett Fleming is providing construction engineering and inspection (CEI) services for the improvements, which are expected to be complete in 2020.

What We Did

The project features 25 new bridge structures, including 10 sets of mainline dual bridges. CEI work includes construction inspection of the roadway, bridges, and erosion control measures, as well as materials sampling and testing to ensure that all work is completed to NCDOT specifications. The team also is responsible for advanced-level inspections of embankment construction, storm drainage, base course, asphalt placement, and guiderail installation. Gannett Fleming’s early involvement and extensive materials, roadway, drainage, and utility experience, enabled the identification and resolution of major conflicts between construction plans and field conditions, mitigating project schedule delays and avoiding costly changes.

Our firm’s work includes inspecting the relocation of power and telecommunications infrastructure to ensure uninterrupted service to customers during construction and enable the contractor to maintain permit compliance. The team also is performing construction inspection of new water lines installed in the project area.

Key Features

  • Inspection and materials testing ensure full compliance with NCDOT specifications
  • Relocated utility infrastructure maintains service to customers during construction
  • Stormwater drainage systems and erosion control measures prevent roadway flooding and storm damage.
