South Massachusetts Avenue Corridor Safety Improvements Project

Massachusetts Avenue, from Sidney Street at the edge of Central Square to Memorial Drive at the Charles River, is a busy transportation corridor with a variety of uses. Anchored at one end by Central Square and University Park, and at the other end by MIT, the street is heavily used by pedestrians, bicyclists, vehicles and transit users. The corridor has a growing variety of restaurants, shops and commercial uses.  The street was redesigned and reconstructed (2008) with new elements including on street bicycle lanes, pedestrian crossings and a plaza at Lafayette Square. Mass. Avenue is one of the busiest bus routes in the city and based on a study by the City, buses experience significant delay and unreliability. It also has a higher than average rate of bicycle crashes compared to other streets in the city. 

In spring 2016 the City Council adopted a Vision Zero commitment to eliminate traffic fatalities and serious injuries. Aligned with this commitment, the City of Cambridge is undertaking this effort to improve safety and reliability for users of the street, particularly cyclists, pedestrians and buses. The work will be accomplished mostly through quick-build methods such as re-striping, signal re-timing, signage and installation of materials like flex-posts, if needed.

The City invites you to share feedback about your experiences traveling on Massachusetts Avenue between Sidney Street and Memorial Drive using a Wikimapping tool. The input you provide on the Wikimap will be used to help inform the redesign of this segment of Massachusetts Avenue.
