Beacon Street (Arlington Street to Mass. Ave)

In 2018, we made design changes to slow drivers and improve safety. Now, want to make the intersection of Beacon Street and Berkeley Street safer and close a key gap in the bike network between Arlington Street and Berkeley Street.

In 2018, we made design changes to Beacon Street, between Arlington Street and Massachusetts Avenue, to improve safety for everyone. Our project goals were to:

  • manage vehicle speeds
  • reduce the number and severity of crashes, and
  • increase walking comfort.

Now, we want to build on those changes. The intersection of Berkeley Street and Beacon Street remains a safety challenge. And, there is a gap in the bike network between Arlington Street and Berkeley Street.

Previous project updates


On Thursday, May 2, 2024, we hosted a virtual public meeting to share an update on projects in the Back Bay neighborhood. The meeting was publicized on our project websites, via email to subscribers to the Boylston Street, Berkeley Street and Connect Downtown lists, and on Streets Cabinet social media channels. Additionally, Neighborhood Services and elected leaders publicized the meeting to local stakeholders.

Design completed - Construction update
  • Boylston Street Bus and Bike Lane
  • Berkeley Street Better Bike Lane - Modified
  • Clarendon Street Bus Lane
In Design
  • Beacon Street and Arlington Street - Modified
  • Dartmouth Street Better Bike Lane - New
  • Dartmouth/Stuart Safety Improvements - New

We share the data inputs and results of our traffic analysis to support the redesign of the Beacon Street/Berkeley Street intersection in Back Bay.

How we design traffic signals:

  1. Gather traffic data to understand current conditions.
  2. Use traffic modeling software to test different designs.
  3. Our goal is to find a balance between safety, access, and keeping traffic moving smoothly for everyone.

During the day, we will paint the new configuration with a longer-lasting material. We anticipate needing several days to complete the painting. Please look for posted signs to understand any parking restrictions associated with our work.

We will install flex posts to provide better guidance on parking locations. Please remember to park to the left of the buffer area.


We are working with our contractor to re-time the traffic signals this spring. We will give people walking a head-start before drivers are allowed to turn. We are also adjusting the signals so that the WALK light comes on automatically at almost every crosswalk.


Additional signage changes will come this spring as well. We will be adding turn restrictions for drivers at red lights and signs to remind everyone to look out for one another.

We begin implementing our plans during the winter of 2017-2018.

Pavement markings
  • Expect work on Wednesday, December 20, through Friday, December 22. Parking will be restricted on the even side of Beacon Street.
  • Crews will be working during daytime hours (7 a.m. - 3 p.m.) to implement the road diet from Berkeley Street to Massachusetts Avenue. Posted signs will include upcoming dates for work and fliers will be distributed in the neighborhood. 
  • We are focused on installing the "long lines" that will shift the parking lane to a new location. When they have completed a block, they will place cones in the buffer area. Please park to the left of the cones.
  • We are scheduling crews to install additional signage over the winter months. Expect minor parking restrictions.
  • To include the pedestrian head-start at each intersection, we need new signal controllers and different signal faces. We have ordered the new equipment. We will install it as it arrives.
  • At Beacon/Dartmouth, the signal changes require pavement marking changes on Dartmouth. We plan to install those pavement markings in the spring. We will change the signal shortly after that.

We hosted a drop-in meeting on October 2, 2017. More than 100 attendees reviewed the plans in detail and asked questions to the full design team. You can view the meeting materials below.

Data analysis poster (PDF)

We summarized key data collected for the project. This includes the number of people walking and driving, traffic volume, and speeding drivers.

We plan to have the WALK light appear automatically in most locations, while giving pedestrians a six-second head start.

Outreach, education, and next steps poster (PDF)

With the new design, we’re planning more outreach. We'll also continue to collect data.

Review Meeting Materials

Give your feedback

We’ve put together a list of potential project objectives and a list of tools / interventions that can be used to reach the objectives.

We need to know your priorities so we can explore the right types of changes. Read through the potential objectives and tools / interventions and then share your priorities for Beacon St.

Central Library, Commonwealth Salon 700 Boylston Street

The Boston Transportation Department held a community meeting to discuss transportation safety improvements for Beacon Street. We collected ideas from people who walk, bike, and drive along Beacon Street to shape the project’s objectives and identify the design interventions that should be considered.

The Boston Transportation Department and the Boston Police Department attended a special meeting called by the Neighborhood Association of Back Bay to discuss pedestrian safety and ways to reduce speeds on Beacon Street.

Speed feedback signs give motorists instant feedback on how fast they are going and flash when a driver exceeds the speed limit.
