Beginning this Thursday, March 28th, National Grid will begin an extensive project on Main Street between Forest St. and Salem St. For several weeks, traffic will be reduced to 1 lane on Main St. heading southbound (i.e. Melrose toward Malden Square). If any part of your commute involves traveling in this area of the city, you are going to want to leave extra time or find alternate routes.
Police officers will be on duty for traffic rerouting and detours. Additionally, signage will be placed on adjacent streets instructing motorists on the proper detours.
