The Grounding McGrath Study final report is now available. Its primary recommendation is to remove the McCarthy Overpass in Somerville and replace it with a six-lane at-grade urban boulevard. The recommended improvements to the McGrath Highway will be paired with the MBTA Green Line Extension to Somerville and Medford to help transform the neighborhoods surrounding them.
This report is the culmination of an extensive feasibility study and public involvement process that evaluated the benefits and impacts of removing the McCarthy Overpass, an elevated structure that carries Route 28 over Washington Street in Somerville that was in need of significant repairs. Built in the early 1950’s, the Route 28 corridor’s elevated structures pre-date not only the Central Artery tunnel, but also the original Interstate 93 elevated viaduct through Boston, Somerville and Cambridge. This construction severed Somerville and its neighborhoods with a steel and concrete barrier.
The study addresses not only the technical challenges of safety and long-term maintenance of the transportation infrastructure but also reconnecting the community, increasing accessibility to all transportation modes, and promoting economic development. The Grounding McGrath Study required a multi-faceted approach to invite community engagement and evaluate a broad range of desired outcomes.
