​Daytime Single-Lane Closures Required Along Four Miles of Roadway 

(August 18, 2022) – The Maryland Department of Transportation State Highway Administration (MDOT SHA) will begin a project next week to improve the driving surface and enhance safety on MD 77 (Foxville Road) between the Frederick County/Washington County line (west of Brown Road) and Catoctin Hollow Road in Frederick County.

Starting at 8 a.m. Monday, August 22, single-lane closures with a flagging operation will be in effect weekdays on MD 77. Work will be performed Mondays through Fridays, 8 a.m. to 4 p.m. and is expected to continue through October. MDOT SHA will maintain access to trails and a parking lot located along MD 77 for visitors to Cunningham Falls State Park.

Work includes:

  • Removing the roadway’s top layer.
  • Repairing depressions to smooth out the road surface.
  • Adding a new layer of asphalt.

MDOT SHA contractor Francis O. Day Company Inc., of Rockville, will use signs, cones, electronic arrow boards and flaggers to alert and guide motorists through the work zone.

MDOT SHA works hard to maintain safe traffic mobility in work zones for our crews as well as our customers. Drivers need to stay alert, focus on driving, and look for reduced speed limits as well as other driving pattern changes. Please drive like you work here and slow down in construction zones. ​

Motorists in need may dial #77 on their mobile device for roadside assistance.
