This Project will complete final design and construction to create accessible stations along the Green Line B-Branch in Boston, MA. Work will consist of rebuilding station platforms to raise and widen boarding areas to achieve accessibility requirements to ensure that each station offers compliant pathways to the Public Right-of-Way. The project will also improve safety by separating platforms from vehicular traffic. Barriers to accessibility at multiple grade crossings will be addressed, ensuring safer and more convenient use for passengers. Track work and accessibility improvements at Boston University will be completed under separate projects.
