In 2019 , Cambridge City Council passed the Cycling Safety Ordinance, which requires the construction of separated bike lanes when streets are being reconstructed as a part of the City’s Five-Year Plan for Streets and Sidewalks and they have been designated for greater separation in the Bicycle Network Vision.
In 2020 , the Council passed amendments to the Cycling Safety Ordinance, which set ambitious requirements for the installation of approximately 25 miles of separated bike lanes within five to seven years. The location of these facilities will be informed by both the Cambridge Bicycle Network Vision and specific requirements in the Ordinance.
The Ordinance text is available in Chapter 12.22 of the Cambridge Municipal Code .
In general, the amendments to the Ordinance require the installation of separated bike lanes on:
all of Massachusetts Ave;
Broadway from Quincy St to Hampshire St;
Cambridge St from Oak St to Second St;
Hampshire St from Amory Street to Broadway;
Garden St, eastbound from Huron Ave to Berkeley St, and westbound from Mason St to Huron Ave;
and11.6 miles of separated bike lanes in other locations that are a part of the Bicycle Network Vision.
We’ve provided more details about the specific requirements and the associated timelines, and the projects that we have or will install that are related to this Ordinance.

In 2022, the Cambridge City Council requested that the City conduct a study to conduct a study on the impacts to businesses when separated bike lanes are installed on commercial corridors as part of the Cycling Safety Ordinance. The City's Community Development Department began data collection in 2023. Read more about the Cycling Safety Ordinance Economic Impact Study here .
