Projects

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.

• MassAve4 - Mass Ave from Dudley St to Beech St; Roseland St to Waterhouse St; Garden St to Church St, in the northbound direction (this segment is Peabody St); and Dunster St to Plympton St.
• The Rest of Mass Ave - All segments of Mass Ave, from Memorial Drive to Alewife Brook Parkway, that are not included in the MassAve4.
• Special4 - Broadway from Quincy St to Hampshire St; Cambridge St from Oak Street to Second St; Hampshire St from Amory Street to Broadway; and Garden St, eastbound from Huron Ave to Berkeley St, and westbound from Mason St to Huron Ave.
• Other Locations - Locations that are not included in the three previous categories, but have been designated for greater separation in the Bicycle Network Vision.

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.

The information below is grouped by “separated bike lane year” (May 1 – April 30 of the following year) when construction began or the project was completed.

Second Annual Cycling Safety Ordinance Progress Report

In June 2022, we released our second annual Cycling Safety Ordinance Progress Report, detailing progress made to install separated bike lanes on key corridors from May 2021 to April 2022 and outlining work planned for the next year. Click here to read the report. 

Current and Planned Projects

Year 3 Projects: 4.23 miles planned

Year 3 Projects for the period between May 1, 2022, and April 30, 2023 are listed below. We will include additional sections as determined. It is important to note that the workplan laid out here for the upcoming year reflects the best of our knowledge at the time of this report and is subject to change. There are various factors that can impact implementation schedules, including the need for extended community engagement and coordination with utility work or other construction. The information in the “Status” column reflects the current status of the project.
