The third annual Cycling Safety Ordinance (CSO) Progress Report

3 Introduction Cambridge’s Cycling Safety Ordinance sets ambitious requirements for the installation of about 25 miles of separated bike lanes between 2020 and 2027. The Ordinance requires annual progress reports on improvements made each year. Many deadlines and timelines set out in the Ordinance follow a “Separated Bike Lane Year” between May 1 and April 30. This third annual report: • Details improvements made in Separated Bike Lane Year 3 (May 1, 2022 to April 30, 2023) • Outlines the work planned for Separated Bike Lane Year 4 (May 1, 2023 to April 30, 2024)

Installation Summary

• In Year 1, we completed or started construction on 4.12 miles of separated bike lanes. • In Year 2, we completed or started construction on 2.11 miles of separated bike lanes. • In Year 3, we completed or started construction on 3.58 miles of separated bike lanes. • In Year 4, we plan to install or begin construction on 4.73 miles of separated bike lanes. Streets where Cambridge has installed or started construction on separated bike lanes as part of the Cycling Safety Ordinance.

4 Background In 2019, the Cambridge City Council passed the Cycling Safety Ordinance. The Ordinance requires that the City construct separated bike lanes on streets designated for “greater separation” in Cambridge’s Bicycle Network Vision, if the street is being reconstructed as part of the City’s Five Year Plan for Streets and Sidewalks.

In 2020, the Council passed amendments to the Ordinance, setting ambitious requirements for the installation of approximately 25 miles of separated bikes 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.

In general, the Ordinance requires the installation of separated bike lanes on: • All of Massachusetts Avenue • Broadway from Quincy Street to Hampshire Street • Cambridge Street from Oak Street to Second Street • Hampshire Street from Amory Street to Broadway • Garden Street, eastbound from Huron Avenue to Berkeley Street, and westbound from Mason Street to Huron Avenue The Ordinance also requires that the City install 11.6 more miles of separated bike lanes in other locations that are part of the Bicycle Network Vision.

5 In its requirements and timelines, the Ordinance distinguishes between quick-build and construction. Quick-build methods include pavement markings, flex-posts, signage, and signal changes, and can usually be installed in the course of a few weeks or months. The City reports quick-build separated bike lane mileage in the year that the project is installed. Construction involves more extensive changes, including potentially moving curbs and/ or removing medians.

Work becomes more complex any time we dig into the ground, and construction projects may include work on the infrastructure (e.g., water, drainage and sewer pipes, traffic signals) that we have underground. Construction projects often take multiple years to complete, and the City reports constructed separated bike lane mileage in the year that construction begins.
