Maryland Route 77 Detour Information

The Maryland Department of Transportation will assist the Maryland Environmental Services with the renovation and replacement of a sewer line under Maryland Route 77 (Foxville Road) between Pryor Road and Park Central Road in Thurmont, Maryland. The project requires a road closure which is expected to remain in effect through May 2024.

This section of Maryland Route 77 is closed in both directions. Park visitors coming from State Route 15 will be detoured to Maryland Route 550 (Sabillasville Road) to Foxville Deerfield Road. Trucks and other large vehicles must use a different detour route.
