Cambridge Street Bicycle Safety Demonstration Project

Cambridge Street, from Inman Square to Quincy Street, is a busy transportation corridor with a variety of uses, ranging from the Cambridge Rindge and Latin High School/War Memorial complex and Cambridge Hospital to small retail shops and residential buildings. This is also a corridor without marked bicycle facilities and 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 now undertaking a demonstration project to create separated bicycle facilities from Inman Square to Quincy Street. The project is scheduled to be implemented summer 2017 and will be created using temporary materials such as paint, flex posts, etc. The goal of the project is to improve the safety of all users and make this section of Cambridge Street a more attractive corridor for cycling, walking, taking transit and enjoying the neighborhood.

See “The Latest” tab below for up-to-date information. Once the demonstration has been in place for several months, and users have gained an understanding of the new design, observations will be conducted and data collected to assess how the street is functioning and whether further modifications should be made.


Installation for the Cambridge Street Separated Bicycle Facility project is expected to begin the evening of August 20th, weather permitting, and continue through that week. This project will create separated bike lanes on Cambridge Street between Quincy and Fayette Streets. Following a robust community process, the final street design includes two travel lanes, one parking lane, and two separated bicycle lanes. Implementation will consist of new pavement markings and signage. With this project, cyclists off all ages and abilities will have a safer way to travel along Cambridge Street between Harvard Square and Inman Square. Signage will be posted in advance of implementation to alert drivers to upcoming changes in parking (temporary and permanent). See the project flyer for a description of benefits and more information.

March 2017: Begin public engagement – meet with stakeholders and review design issues

Apr/early May: Conduct parking study, first public meeting, begin concept formulation and continue meetings with stakeholders

May: Refine concept and hold second public meeting and produce signage and pavement markings plans

August: Implementation

Fall 2017: Data collection/evaluation

Given the recent bicycle related tragedies in 2016, the community has asked the City Manager to accelerate the implementation of the Cambridge Bicycle Plan and to implement projects including separated bicycle lanes more quickly. Implementation for a project on Cambridge Street is planned to start in summer of 2017. In December of 2016, two sections of separated bicycle facilities were installed on Mass. Avenue, in Central Square and between Waterhouse Street intersection and Everett Street, in front of Harvard Law School. Inman Square is also being redesigned and more information on that project may be found here.

Additional separated facilities are being studied for implementation this spring and fall.
