MCDOT relies on resident reports of potholes, and as they make their rounds, repair crews also stop to fill any other potholes encounter. Residents can report potholes online by creating a service request or by calling the MC311 Call Center at 311 or 240-777-0311, Monday through Friday from 7 a.m. to 7 p.m. Drivers are asked to be cautious and patient when encountering crews filling potholes.
MCDOT fills potholes on 5,000 lane miles of County-maintained roads. The Maryland State Highway Administration (MSHA) fills potholes, plows snow and maintains numbered routes in the County, such as Maryland routes 355 or 97. MSHA can be reached at 301-513-7300. In addition, municipalities, such as the cities of Rockville or Gaithersburg, handle their own repairs.
