Accessibility Statement The City of Cambridge does not discriminate, including on the basis of disability. We may provide auxiliary aids and services, written materials in alternative formats, and reasonable modifications in policies and procedures to people with disabilities. For more information contact us at tpt@cambridgema.gov , 617-349-4700 (voice), or via relay at 711.
In the coming years, we are going to add significantly to the city’s network of separated bike lanes. We will use this page to provide updates on our progress on an ongoing basis.
There are four categories of projects: MassAve4, The Rest of Mass Ave, Special4, and Other Locations.
Typically, we must complete a separated bike lane before we can count it toward the requirements of the ordinance. Construction projects in The Rest of Mass Ave and Other Locations categories are exceptions; they count when construction begins.
