Urban Ring Transit Expansion project

Urban Ring

The Urban Ring project, managed by the Massachusetts Department of Transportation (MassDOT), was a transit expansion concept to connect existing radial transit lines (subway, commuter rail, and bus), leading to shorter transit trips and fewer transfers. It was intended to improve access to some of the area’s fastest growing districts, including Kendall Square and East Cambridge, Longwood Medical and Academic Area (LMA), and the South Boston Waterfront. The project corridor encompassed parts of Boston, Chelsea, Everett, Medford, Somerville, Cambridge, and Brookline. The preferred concept included frequent bus rapid transit service, which would operate partly in exclusive bus lanes and tunnels and partly in mixed-use traffic.

An estimated 13,000 daily riders were predicted to board the Urban Ring system at the Kendall Square station alone. The Sullivan Square – Kendall Square – Longwood Medical Area route had the largest potential ridership for a new transit system in the region.

This initiative stalled in 2010 and materials are no longer available on the MassDOT web page previously developed for the project. However, several initiatives since that time have built on this process  to explore options to connect some of these important areas in the shorter-term.
