South Massachusetts Avenue Corridor Safety Improvements Project

The South Massachusetts Avenue Corridor Safety Improvements Project is a "quick-build" project on Massachusetts Avenue between Sydney Street and Memorial Drive focusing on safety and accessibility, and features separated bike lanes in both directions for the majority of the corridor. Other changes include:

  • Signal timing changes at intersections to reduce conflicts and crashes
  • Sections of bus lane toward Memorial Drive
  • A new crosswalk across Massachusetts Avenue at Windsor Street, to be installed in spring 2019
