Gravel and Tar & Chip

Frederick County gravel roads are graded on an as-needed basis. Every spring the county will provide dust control around April or late May.

To report potholes, washboard effect (ruts), additional stone, etc., please fill out a county work request form or contact us via email or by phone at 301-600-1564.

Tar & Chip Roads



The Office of Highway Operations’ objective is to seal all macadam roads to prevent water from seeping through the surface and causing damage. We try to cover approximately 1/4 of our tar and chip roads per year.
