The East Deer Park Bridge, also known as the Humpback Bridge, which spans the CSX railroad tracks between the City of Gaithersburg and the Town of Washington Grove, is closed to traffic until late August. The bridge is being upgraded to meet current structural standards. Train service will not be disrupted.
East Deer Park Drive will be closed between Central Avenue and Railroad Street. Signs along the detour route instruct motorists to take Central Avenue, Oakmont Avenue and Railroad Street around the construction.
