Traffic and construction updates for the Route 18 Weymouth-Abington Improvements Project

Current details on construction progress

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.

What's New

MassDOT's contractor, P. Gioioso & Sons, implemented a new traffic pattern to perform work at the Route 18 bridge over the Commuter Rail tracks. Lane widths have narrowed, with no shoulder in the work zone. Work along the west shoulder has begun.

Preparatory work has started on the bridge carrying Route 18 over the railroad tracks, just north of the South Weymouth station, and will continue in fall 2018.

Underground utility work needed for road widening and new traffic signals is ongoing in several locations between the bridge over the MBTA Commuter Rail and Abington town line. New signals at Pond Street and Trotter Road will be installed in 2019.

Relocation of utility poles and overhead wires is ongoing in several locations and may result in short-term service outages, as scheduled by utility companies with customers. This work will continue through 2020.

Construction of retaining walls to support road widening is ongoing in several locations and will continue through the end of 2018.
