Due to a water main break at the Rte 2 Rotary in Concord, Rte 2A West (Elm St) traffic will be detoured to Rte 2 West on to Rte 27 North in Acton for morning commuter traffic. Rte 2A East traffic will travel Eastbound to the Concord Rotary. Detour signs are in place. Updates to follow as they are made available. Thank you for your patience.
