Upcoming railroad construction road closuresNorfolk Southern Railroad has notified the Chattanooga Division of Transportation of maintenance requirements necessitating the closure of multiple grade crossings next week, with a major traffic impact expected, according to the City of Chattanooga Department of Public Works / Transportation Division. They say due to the complex nature of repairs within the railroad right of way, specific start times for individual closures may be difficult to determine. Estimated dates and locations for these closures and associated detours are provided below. Should any closure exceed the projected timeframe, Norfolk Southern will notify the City and subsequent updates will be issued to the public. Motorists are advised to observe all posted detour signage, which will serve as the primary indicator of an active closure.
