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.
