Project Summary


MassDOT is proposing to widen and make improvements to a portion of Route 18 in Weymouth and Abington. The project includes reconstruction of portions of a 4.1-mile segment of Route 18 and the bridge that carries Route 18 over the MBTA railroad tracks in Weymouth. The project extends from the intersection of Carmada Road/Highland Place southbound to just before the intersection of Randolph Street (Route 139).

Construction will include widening the roadway from a two-lane rural arterial with variable shoulders and minimal sidewalks to a four-lane undivided arterial with uniform shoulders and sidewalks along both sides of the entire roadway. The project will address traffic congestion, intersection upgrades, and traffic signals, as well as improve the roadway surface and curbing conditions. The proposed improvements and widening will improve safety and circulation for vehicles, pedestrians, and bicyclists. In addition, the project will support economic development along Route 18 and the surrounding area, including the development of the former South Weymouth Naval Air Station in Abington, Weymouth, and Rockland.

Overview of Environmental Review Process


MassDOT is continuing a full environmental review process for this project in compliance with all applicable federal and state regulations to avoid, minimize, and mitigate impacts to environmental resources. MassDOT will file applications and/or documentation to comply with all applicable Federal regulations including the National Environmental Policy Act with the Federal Highway Administration, a Section 404 permit with the United States Army Corps of Engineers, a Water Quality Certification Application with the Massachusetts Department of Environmental Protection (MassDEP), the Wetlands Protection Act with the Weymouth and Abington Conservation Commissions and MassDEP, and Massachusetts Endangered Species Act through the Natural Heritage and Endangered Species Program. Most of these permit applications will be filed in 2012/2013 following the completion of the 25% design.

The project was initially filed with Massachusetts Environmental Policy Act (MEPA) as part of the South Weymouth Naval Air Station's Environmental Notification Form (ENF) (EEA# 11085R). A Supplemental Environmental Impact Report (SEIR) was filed with MEPA in 2012 resulting in the issuance of a Secretary’s Certificate on September 28, 2012, indicating the project adequately and properly complies with MEPA. A Finding of No Significant Impact under NEPA was issued on September 15, 2009 for the Environmental Assessment prepared for Route 18.
