From April 7 - May 28, Norfolk-Southern Railroad will be conducting track maintenance operations at various railroad grade crossings in the counties of Guilford, Alamance and Orange. These maintenance operations will require the services of NCDOT Traffic Services personnel to establish traffic control and detour routes. Each of these activities that impact roadways which are on the state highway system will be entered into the Travelers Information Management System. Through this system the public can access the most current available information by calling 511 or by using the link below. Closures that Traffic Services believes will have a significant impact on traffic will be preceded by a press release describing the specifics of the event.
