New and Current Bicycle Projects

Updated November 2018

The City of Cambridge continually evaluates locations where large and small scale bicycle infrastructure improvements can be made to increase safety and meet our Vision Zero goals. This page highlights recently completed bicycle facility improvement projects, but it is not an exhaustive summary of all bicycle improvements.

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:
