What's New

MassDOT hosted a pre-construction public meeting on October 5 in Weymouth and presented the same information to the Abington Board of Selectmen on October 30. See the Project Documents & Meeting Materials section below for the presentation and meeting summary. You can also view videos online of the October 5 meeting and the October 30 meeting.

Early Action Work in the project area has begun, to prepare for construction. The work includes relocations by utility companies and surveying. Signage installation began the week of November 6. The contractor is currently constructing retaining walls in several locations within the project corridor.

Traffic Information

MassDOT will maintain one lane of travel in both directions throughout construction.

The project requires three weekend shutdowns of the MBTA Kingston/Plymouth Commuter Rail line. The shutdowns are necessary for the contractor to safely replace the bridge that carries Route 18 over the railroad. MassDOT and the MBTA are coordinating closely with the contractor. The project team will announce the shutdowns with advance notice. During the shutdown, MassDOT will detour traffic from Route 18 onto Pond Street. Buses will also replace trains on the MBTA Kingston/Plymouth Commuter Rail line. The MBTA and MassDOT encourage commuter rail passengers to use the Middleborough/Lakeville line during the three weekend shutdowns, if possible.

About the Project

This project is reconstructing and widening Route 18 (Main Street/Bedford Street) in Weymouth and Abington. It will widen the roadway to two lanes and a shoulder in each direction throughout the project corridor. The corridor is a four-mile stretch of Route 18 from Middle Street/West Street (just west of Route 3) in Weymouth to Route 139 in Abington. The project also includes:

  • replacing the bridge that carries Route 18 over the MBTA Kingston/Plymouth Commuter Rail line in Weymouth
  • reconstructing existing intersections with traffic signal updates and safety improvements
  • installing new emergency traffic control signals at the Abington Fire Station
  • new sidewalks for pedestrians and accessibility improvement
  • bicycle accommodations
  • stormwater management updates

The project is using accelerated construction techniques to minimize traffic impacts. The contract incorporates incentives and disincentives to ensure timely completion of project milestones.
