Third Annual Cycling Safety Ordinance 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.

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.
Third Annual Cycling Safety Ordinance Progress Report

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.

requirements and the associated timelines and provides additional links to individual Cycling
Safety Ordinance projects.

Future Projects
Besides the 4.73 miles of separated bike lanes planned for
Separated Bike Lane Year 4, we plan to make progress on the
following projects.
Cambridge Street
In Fall 2023, we plan to start outreach on a project that will add about
two miles of quick-build separated bike lanes to Cambridge Street
between Oak Street and Second Street. We expect to install these
lanes in Separated Bike Lane Year 5 (between May 1, 2024 and April
30, 2025).
Central Square: Massachusetts Avenue between Sidney
Street and Bigelow Street
We plan to construct separated bike lanes on the section of
Massachusetts Avenue between Sidney Street and Bigelow Street
through Central Square. This will be one element of a major capital
project that will upgrade the overall streetscape. The project will
include:
• Upgrading sidewalks and crosswalks
• Improving bus stops
• Urban design and landscape improvements
• Rehabilitating existing public and private utilities
• Full-depth reconstruction of the roadway
The project will engage the community and be designed to work
in harmony with adjacent projects at Carl Barron Plaza and River
Street.
In Separated Bike Lane Year 3, the City’s Department of Public
Works began developing a scope for the design process and
started initial coordination and engagement. This summer, the
City will hire a consultant team to lead the design process and
community engagement. In September 2023, we expect to
advertise the opportunity to join the project’s working group.
A FY23 budget appropriation of $5 million will support the project
design. We anticipate a FY25 budget appropriation of $45 million
to support the project’s construction. We are on track to begin
construction by December 31, 2025, as required by the Ordinance.

Cycling Safety Ordinance Mass Ave Partial Construction and Mass Ave Harvard
Square, formerly the MassAve4 Program: Year 3 Update
The Cycling Safety Ordinance identified four segments of Massachusetts Avenue where
installing separated bike lanes would be challenging due to unique complicating factors which
include significant underground utilities, major bus stops, a center median, and the MBTA’s
overhead trolley bus wires.
These four segments, collectively referred to as the MassAve4 since the passage of the
Ordinance, are defined below. With some of the limits of the projects changing, there are
no longer four unique segments, so we have updated the names of the projects to be more
relevant.
Mass Ave Partial Construction (Waterhouse to Alewife Brook), formerly MassAve4
Segments A and B
• Dudley Street to Beech Street (A) - north of Porter Square
• Roseland Street to Waterhouse Street (B) - south of Porter Square
Mass Ave Harvard Square, formerly MassAve4 Segments C and D
• Church Street to Garden Street (C): northbound bus stop at Harvard University’s Johnston
Gate
• Plympton Street to Dunster Street (D): bus stop/layover at Harvard University’s Morgan
Gate
Third Annual Cycling Safety Ordinance Progress Report
16
In April 2022, the City submitted a report to the City Council with recommended
approaches and timelines for the installation of separated bike lanes in these four
segments.
The full report can be found at this link, or under the “MassAve4” section at
www.cambridgema.gov/cso-timeline.
In summary, the report recommended:
• A partial construction approach for Segments A and B. The center median
would be removed except at key locations for pedestrian crossings, traffic
signals, and traffic control. Separated bike lanes would be installed using flex
posts or pre-cast concrete curb separation. The MBTA has committed to working
with the City to remove the overhead catenary wires and poles that supported
its now-retired trolley bus infrastructure. The removal of this above-ground
infrastructure provides significantly more design flexibility for curbside uses.
• A full construction approach for Segments C and D. Due to heavy bus stop
activity and the need for bus layovers, full construction would be needed to
implement separated bike lanes at the bus stop locations. The recommended
project limits were Mass Ave from Plympton Street to Garden Street.
The City Council approved these recommendations, and Mass Ave Partial
Construction and Mass Ave Harvard Square are now included in the City’s Five-Year
Capital Plan. The FY24 Budget includes $50 million for Mass Ave Partial Construction,
and the FY23, FY24, and FY25 budget includes a total of $17 million for the full
construction approach for Mass Ave Harvard Square in the Complete Streets budget.
During Separated Bike Lane Year 3, City staff and the City’s engineering consultants
conducted detailed analyses, evaluated the condition of the City’s utilities, and
coordinated with private utility companies, the MBTA, Harvard University, and the
Cambridge Historical Commission. Year 3 activities for the MassAve4 segments are
described in more detail below.
Mass Ave Partial Construction (Waterhouse Street to Alewife Brook Parkway),
formerly MassAve4 Segments A and B
To allow for a more thoughtful evaluation of the full corridor between Waterhouse
Street and Alewife Brook Parkway, the City expanded the limits of the partial
construction project beyond MassAve4 Segments A and B. The City has extended
project limits to include two segments where quick-build separated bike lanes were
previously installed. These two segments, the section of Mass Ave near Porter Square
and the section north of Dudley Street, are adjacent to Segments A and B. Together,
the four segments comprise a contiguous two-mile multimodal corridor bustling
with retail shops, restaurants and other uses and activities. The expanded project is
referred to as the “Mass Ave Partial Construction Project.”
Third Annual Cycling Safety Ordinance Progress Report

During Separated Bike Lane Year 3, the City has been evaluating the existing surface
and subsurface infrastructure in the area, conducting traffic analyses, and identifying
potential improvements.
A 14-member working group representing a diverse set of perspectives was
appointed by the City Manager in April 2023, and a kickoff meeting is scheduled for
May. The Mass Ave Partial Construction Working Group will help shape the design of
the street improvements and the streetscape.
Summary of Year 3 Activities
• Expanded the project limits to allow for a unified design approach
• Announced a working group, interviewed applicants, recommended members,
and appointed members
• Collected additional traffic count data and conducted traffic analyses
• Researched record drawings and documentation for existing infrastructure
• Performed various field activities (surveys, assessments of existing conditions of
utilities and infrastructure, traffic counts, existing tree review)
• Coordinated with Eversource regarding necessary upgrades to gas infrastructure
• Coordinated with the MBTA regarding bus operations, ridership, removal of the
electric trolley infrastructure and the renovation of the North Cambridge Bus
Facility
Planned Year 4 Activities
While continuing with many of the Year 3 activities, the following activities are planned
for Year 4:
• Meet and collaborate with the working group: on-board, provide background
information, and dive into the details of the corridor.
• Hold meetings with Cambridge transportation committees, the public, various
City departments, and other stakeholders
• Develop design concepts and advance the design phases
• Review sewer and stormwater collection system inspections and identify
necessary repairs
• Evaluate the condition of the water distribution system

Mass Ave Harvard Square, formerly MassAve4 Segments C and D
Separated Bike Lane Year 3 focused on fully developing the project scope for Mass
Ave Harvard Square while actively engaging with the public and stakeholders. A
newly-reconstructed streetscape will be a focal point for visitors, residents, students,
and tourists for years to come.
The City has been evaluating the condition and functionality of the existing surface
and subsurface infrastructure and conducting additional traffic analyses to
understand traffic and pedestrian flows through the proposed project limits. The
concept and 50 percent design phases have emphasized the need to upgrade
infrastructure, enhance lighting, and optimize traffic signals to improve safety and
accessibility for pedestrians, cyclists, and public transit users in this historically
significant area of Cambridge.
Following a multidisciplinary review of the project and its goals, and consideration of
comments received from the community to date, the City expanded the project limits
to the south to include the bus stop at Bow Street, and to the north to include the bus
stop at Dawes Island and the right turn slip lane from Mass Ave onto Garden Street.
This expanded scope provides for a consistent, unified design.
Summary of Year 3 Activities
• Expanded the project limits to improve movements for people walking, cycling,
taking transit, and driving into and through Harvard Square
• Held meetings with the Cambridge transportation committees (Bicycle,
Pedestrian, Transit Advisory) on September 28, 2022, and the public on October
22, 2022, to present a project overview, design considerations, and conceptual
design overviews.
• Researched record drawings and documentation for existing infrastructure
• Developed concept and 50 percent designs
• Performed additional traffic analyses
• Coordinated with various City departments to identify the full scope of necessary
infrastructure replacements (trees, water, electrical, lighting, traffic signals and
controls, sewer, drainage)
• Coordinated with Harvard University’s Transportation, Engineering, and Utility
Departments
• Coordinated with the MBTA regarding bus operations, ridership, and Red Line
infrastructure
• Coordinated with the City’s kiosk and plaza construction projects
• Coordinated with Eversource regarding necessary upgrades to gas infrastructure
Third Annual Cycling Safety Ordinance Progress Report

Planned Year 4 Activities
While continuing with many of the Year 3 activities, the following activities are planned
for Year 4:
• Hold meetings with Cambridge transportation committees, the public, various
City departments, and stakeholders
• Develop 90 percent design plans that include construction drawings and
specifications for all engineering disciplines
• Evaluate traffic pattern changes that could improve bus stop and bicycle facility
integration
• Continue advancing the surface grading plan, drainage design, and water
main design with the available information regarding the shallow Red Line
infrastructure
• Complete roadway and pedestrian-scale lighting designs to ensure adequate
street lighting for the proposed streetscape
• Continue coordinating with the MBTA to obtain a license to perform construction
activities above and/or in the vicinity of Red Line infrastructure
• Obtain a permit from the MWRA for test pit excavations near its water
infrastructure
• Monitor progress on other construction activities within the project limits (kiosk
and plaza construction, Eversource)
• Review sewer and stormwater collection system inspections and identify
necessary repairs and upgrades
Year 4 Plans for the Mass Ave Partial Construction and Mass Ave
Harvard Square Projects
These projects have a significant amount of work planned for Year 4. The project
teams will continue advancing the designs, tracking critical path items and
activities, refining construction cost estimates and construction schedules, hosting
community engagement events, and developing strategies for bidding the work and
implementing construction.
