The St. Mary’s County Department of Public Works & Transportation (DPW&T) will perform Surface Treatment / Modified Seal on various roads, located across St. Mary’s County.
Surface treatment will consist of the application of a liquid asphalt emulsion, followed by a new layer of stone. Modern techniques have resulted in a full-width application of an exact quantity of stone, which limits loose stone to a minimum. During the procedure, motorists may experience a brief delay and should use caution. The surface may be driven on immediately behind the roller equipment.
Dates and times could be modified due to weather conditions. During these construction activities, motorists can expect changes in traffic patterns and delays. Please be alert to these conditions.
For more information, please contact the DPW&T Construction and Inspection Division at 301-475-4200 ext. *3531.
