CONCORD, Mass. – Construction activities continue on Phase 1 of the $30.9 million Muddy River Flood Risk Management and Environmental Restoration project in Boston, Massachusetts. On Monday, October 19, temporary night-time work began at Riverway Connector roadway in order to install the relocated 24” sewer line. The existing 24” sewer line must be relocated as part of the daylighting of the former Sears Parking Lot. In order to not impact vehicular traffic flow during the day, this temporary night-time work is necessary. The expected duration of the night-time work will continue two additional weeks until November 13, 2015.

Details concerning this night-time work are as follows:
  • Night work continues through November 13th.
  • Hours will be from 7pm to 5am.
  • Police detail will be provided for the duration of night time work.
  • Vehicular lane(s) closure of Riverway Connector roadway.
  • Excavation of roadway; installation of trench box; installation of timber piles to support the sewer line; laying of 24” sewer line and concrete encasement; installation of precast sewer manhole.
  • Majority of equipment will be limited to excavators, loaders, and dump trucks. Jack hammers may need to be utilized in a temporary fashion for demolition.
  • Before rush hour traffic, the site will be restored daily for vehicular traffic with steel plate or asphalt across the excavation  depending on timing and stage of the task.

These activities are necessary so that the daylighting efforts of the former Sears Parking Lot can begin. We will do all we can to minimize impacts to the public during these activities.
