The project is meant to minimize pollution.
The annual sweep includes approximately 5,000 miles of roadway. Road crews expect to remove more than 3,000 tons of salt, sand and other materials that could otherwise be washed into the county's storm drains.
"That's a huge amount of material that's getting washed into the streams and that's exactly what we're trying to prevent," says Esther Bowring with Montgomery County. "We're trying to keep all of those materials out of the Bay so that the water quality of our rivers and streams is not affected."
Bowring says crews will put up brightly colored signs in each neighborhood a few days before street sweeping begins, giving residents enough time to find alternative parking.
