Press Releases - Department of Transportation

The Montgomery County Department of Transportation (MCDOT) will begin its semi-annual interior washdown to degrease and clean 21 County-owned parking garages in Bethesda, Silver Spring and Wheaton on nights and weekends beginning Monday, April 7. The cleanings will start with the Bethesda garages and are scheduled to conclude with the Silver Spring garages on Wednesday, June 4. 

Some garages will experience partial closures during the cleanings, including select entrance/exit areas and ramps. The full schedule of garage cleanings can be viewed here. 

MCDOT performs spring and fall washdowns to keep garages clean and help keep grease, oil and debris out of local waterways. Regular cleanings also prevent deterioration from prolonged exposure to salt, sand, oils, gas, dirt, pollen and leaves. 

MCDOT contractors will do their best to perform work around garage traffic and parked vehicles and to post signs notifying customers of anticipated impacts.
