Press Releases - Department of Transportation

For Immediate Release: Monday, August 19, 2024

The Montgomery County Department of Transportation (MCDOT) will begin its semi-annual interior washdown to degrease and clean 21 County-owned parking garages in Silver Spring, Bethesda and Wheaton. The cleanings are to begin in the Bethesda garages on Monday, Sept. 9 and end in the Silver Spring garages on Sunday, Nov. 3. The washings will occur on nights and weekends. View the full garage cleaning schedule here.

Every year, MCDOT performs the spring and fall washdowns to ensure the cleanliness of garages and prevent deterioration of the structures from prolonged exposure to salt, sand, oils, gas, dirt, pollen and leaves. Regular cleanings also help to keep grease, oil and debris out of local waterways. Some of the garages have permanent run off filtration systems and others have diverter valves that, when activated during the washdown, change the direction of the water flow from storm to sanitary.

Some garages will experience partial closures that may include select entrance/exit areas and ramps. MCDOT contractors will do their best to complete their work around the garage traffic and parked vehicles and will provide appropriate signage to notify customers of anticipated access impacts.
