The Montgomery County Department of Transportation (MCDOT) has started its semi-annual interior washdown to degrease and clean 21 County-owned parking garages in Silver Spring, Bethesda and Wheaton.
The washings, which will occur on nights and weekends, began earlier in April in the Bethesda garages and conclude with cleanings of the Silver Spring garages in early June. View the full 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. The regular cleanings help keep grease, oil and debris out of nearby waterways.
Some garages will experience partial closures that may include select entrance/exit areas and ramps. MCDOT contractors intend to complete their work around the garage traffic and parked vehicles and to provide appropriate signage to notify customers of anticipated access impacts.
