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.

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.
