Projects Under Construction

  • Concord Ave Sidewalk-(posted 1/20/16)

    On Friday, January 22nd, Concord Ave will be closed From Waltham Street to Spring Street from 9am-3pm. A detour will be set up. Abutters will have access up to the construction zone. See map. The work for the replacement of the Hardy's Pond Brook Culvert will require the road be closed for Friday.  After that, Concord Ave will return to the restriction allowing for one way alternating traffic at the temporary traffic light.  

    At this light, please stop at the designated markings/signage if you have a red signal and proceed through the green phase without delay.  Please bear with us during this critical phase of the project. We recognize that this is an inconvenience and will do our best to minimize the duration.

    The plans include installation of a sidewalk along Concord Avenue from Waltham Street to Spring Street. This project involves construction of a 5 foot wide sidewalk, granite curb, field stone retaining walls and drainage improvements. The culvert carrying Hardy’s Pond Brook will be replaced and the traffic signal at Waltham Street and Concord ave will be upgraded. Current plans are available for viewing at Samuel Hadley Public service building, 201 Bedford Street. Please contact Dave Cannon in Engineering for more information.
