City of Somerville Publishes Final Design for Western Pearl Street

Final Design Update

The City of Somerville has a final design for the Western Pearl Street Reconstruction project. After nearly a year and a half of engaging community members, exploring design alternatives, collecting traffic data, testing emergency operations, and developing a design, the City has prepared a new vision for Pearl Street between Medford Street and McGrath Highway that includes:

Street Condition Improvements

  • A repaved road.
  • Reconstructed sidewalks.

Pedestrian Improvements

  • Accessible curb ramps at all existing and new crosswalks.
  • Curb extensions at intersections along Pearl Street.
  • Raised crosswalks across side streets that intersect with Pearl Street and across Pearl Street at Wigglesworth Street.
  • Raised crosswalks across two sections of Medford Street with a realigned intersection at Pearl Street.
  • Raised intersections at Marshall Street and Walnut Street.

New Bicycle Facilities

  • A two-way protected bike lane from Medford Street to Skilton Avenue.
  • A one-way protected bike lane heading eastbound between Skilton Avenue and McGrath Highway.
  • Enhanced Neighborway connections through Skilton Avenue and Ed Leathers Park connecting to the existing Gilman Street Neighborway.

Parking Changes

  • Two fully accessible parking spaces.
  • Two loading zones.
  • Parking options primarily on the north side of the street.
  • 9 spaces on Pearl Street and 3 spaces on some nearby side streets removed.

Bus Improvements

  • One floating bus stop and 3 in-lane bus stops.
  • Two bus shelters near Marshall Street.

More Amenities

  • More benches around Triangle Park and Medford Street.
  • And 22 new trees.

This design follows the goals set out in the City’s Vision Zero Action Plan to eliminate all traffic fatalities and severe injuries on our streets and the vision of the Somerville Bicycle Network Plan to create a connected network for people of all ages and abilities to travel by bike. The design was shaped from community members’ stories and feedback heard in conversations on the street, at our open houses, in small businesses and community events, in surveys and emailed comments collected throughout design development. Some examples of key features that were guided by community input include:

  • A new crosswalk across Medford Street to increase safety and enhance connectivity to the Gilman Square MBTA Green Line Station and Community Path.
  • A raised intersection at Walnut Street to reduce speeding and prioritize people using the crosswalks in the area.
  • Bicycle options that provide safer connections around the neighborhood and maintain curbside access options for residential, visitor/customer, delivery, and home healthcare worker parking.

For an overview of the project and presentation on the final design, please check out this presentation which includes the proposed parking regulation changes to be presented to the Traffic Commission on February 12.

We are so grateful to all the community members who participated in the development of this design sharing their transportation safety concerns, preferences for design directions and conceptual design options, and providing ideas to incorporate. To learn more about what community members shared with us throughout design development as well as to see how we engaged people, please check out our Pre-Concept, Concept Design Options, and Updated Design Community Engagement Reports.

Additional Street Safety Improvements in the Area

Walnut Street at Pearl Street Traffic Signal Changes

We continue to develop a plan and evaluation process to test decommissioning the red/yellow/green signal on Pearl Street at Walnut Street. We anticipate piloting this signal change following the construction of the raised intersection at this location. We will add any updates to this work on this project website.


Quick-Build Protected Bike Lanes on Medford Street from Pearl Street to School Street

We plan to install protected bike lanes in both directions on Medford Street to connect the new facilities on Pearl Street to the existing two-way bike lanes on School Street heading towards the Community Path. We anticipate removing 4 on-street parking spaces to make space for these quick-build bike lanes. We shared these designs throughout Western Pearl Street public outreach. We believe it makes sense to complete this quick-build work at the same time as the new design for Western Pearl Street is implemented. We will include updates to this work on this project website and on the Medford Street and School Protected Bike Lanes website.


Next Steps for Design

On February 12, we will present to the City’s Traffic Commission to seek approval for the parking regulation changes. These changes primarily include requesting that parking be relocated to the north side of the street, be restricted in locations where new crosswalks are called for and be spaced to comply with the City’s Clear Corners regulations. We are also proposing to convert some 2-hour except by permit spaces to new accessible spaces and loading zones.

Looking Ahead to Construction

Pending Traffic Commission approval, the City will put the design out to bid for a construction contractor later this winter. We will work to secure a contractor so that construction could begin during the 2026 construction season and be completed by November 2027. Once we have selected a contractor and have a preliminary construction schedule, we will provide an update on this project website indicating when and where we anticipate work will begin.
