MassDOT Advisory: Weymouth – Route 18


Roadway closure and detour August 23 through August 26

WEYMOUTH – The Massachusetts Department of Transportation (MassDOT) has announced that a section of Route 18 (Main Street) in Weymouth will be closed to vehicular traffic from 9 p.m., Friday, August 23, through 4 a.m., Monday, August 26. Access will be maintained for abutters and local traffic.

During this time, vehicular traffic will be detoured to Pond Street in order to allow crews to safely and effectively conduct operations as part of the work to replace the bridge that carries Route 18 over the MBTA railroad. There are no expected impacts to MBTA service during this work.

This work is part of the project to a widen and improve a four-mile stretch of Route 18 to two lanes and a shoulder in each direction from Middle Street/West Street in Weymouth to Route 139 in Abington.

Work also includes reconstructing existing intersections with traffic signal updates and safety improvements, adding new sidewalks for pedestrians and accessibility improvements, installing bicycle accommodations, and stormwater management updates. The project is scheduled to be completed in the spring of 2022.

Signage and messaging will be in place to notify drivers of this weekend roadway closure. MassDOT encourages the public to be mindful of potential traffic impacts and seek alternate routes if possible.

Those traveling through the area should reduce speed and use caution. This work is weather dependent and subject to change without notice.
