It’s July and while in the Pyrenees they are celebrating the early stages of the Tour de France, here in the Somerville (well at least here in the Construction Newsletter) we are celebrating all the work happening around the city to improve our infrastructure. In either case, there is a lot to look forward to in the weeks ahead.


As always, we want to make sure you know what is happening, where it's happening, and how it ultimately benefits our city.  


If you have any questions about the work below (or any work in the city) please don't hesitate to reach out to us at construction@somervillema.gov

Intersection Improvements:

Washington Street at Merriam Street - Work Continues (Detour Alert)

Bow Street and Walnut Street - Work Wraps Up

Washington Street at Merriam Street - Work Continues


Work to bring two new crosswalks to Washington Street at its intersection with Washington Terrace and Merriam Street is well underway. This is a part of the City where residents have frequently reported there are not enough places to cross the street.

Crews have started rebuilding sidewalks and creating curb extensions on the south (even-numbered) side of the street. These curb extensions extend further into the roadway than the pre-existing sidewalks, shortening the distance people are required to travel when crossing. They expect to complete sidewalks on the south side and turn to the north (odd-numbered) side in the days ahead.


Similar to the intersection of Bow Street and Walnut Street, the level of the full intersection will be raised to increase safety and accessibility.

Detour Alert:

Washington Street Eastbound


During some phases of this work, Washington St. between McGrath Hwy. and Somerville Ave. will be closed to eastbound (heading away from Union Sq.) traffic.  


Please follow posted detour signage to travel via Somerville Ave. and McGrath Hwy.

Bow Street at Walnut Street - Work Wraps Up


Aside from a few minor punch-list items, work is complete at the intersection of Bow Street and Walnut Street.  


Pavement markings and new signage were installed following paving late last month.

A Note About Pavement on Bow Street


Sometime next year Eversource will restore the portions of the roadway outside the intersection of Bow/Walnut that were disturbed during their recent gas utility project.


Why not this year? While areas where excavation took place have been temporarily patched, it is standard industry practice to wait until a winter season has passed prior to paving following utility projects. Even well-compacted utility trenches can undergo some amount of settling after multiple freeze/thaw cycles resulting in a lower quality surface. Paving after a winter has passed generally provides a more durable, smoother roadway.


Accessibility in our City

What Makes a Sidewalk Accessible?

What we talk about when we talk about accessibility


Prioritizing accessibility means our built environment should be welcoming and usable for everyone—regardless of physical, cognitive, social-emotional, and sensory differences. In this recurring section, we'll talk about the ways in which this principle is incorporated on streets and beyond.

When the City is reconstructing sidewalks (like we did recently at Bow Street and Walnut Street or will be doing later this summer on West Broadway) we often talk about how we are working to increase accessibility. But what makes a sidewalk accessible?


American with Disabilities Act (ADA) Title II requires us to maintain equal access for persons with disabilities to the public right of way—our roadways, sidewalks, bike lanes, pathways, etc. and provides specific guidelines for doing so.

In Somerville, whenever possible, we go beyond these guidelines to provide a safer, more comfortable experience for everyone using our streets, but more on that later. First, here’s what the regulations require:



Sidewalk Width and Slope Requirements

New sidewalks on Holland Street (left) and Elm Street (right) constructed in 2024/25.

For sidewalks we follow criteria set by the ADA as well as Massachusetts Architectural Access Board’s (MAAB) 521 Code of Massachusetts Regulations (CMR). 

  • Sidewalks should be at least 4 feet wide (not including the curb).  
  • A 3-foot-wide, unobstructed (no signposts, plants, furniture, etc.) path must be maintained.  
  • The “cross slope” (perpendicular to the roadway) must be under 2%. This means the sidewalk should be relatively flat.  
  • The “running slope” (parallel to the roadway) can qualify for an exception and be greater than 2% based on the natural topography (which is the case for streets on Somerville’s many hills).

Curb Ramp Requirements

City standard details outlining requirements of an accessible curb ramp.

Similar guidelines exist for curb ramps (the intended point of transition between the roadway and sidewalk).  


  • A detectable warning panel should mark the transition between the roadway and sidewalk for individuals with visual impairments. 
  • The cross slope (perpendicular to the roadway) of the ramp itself should be under 7.5%. 
  • A “level landing” with less than 2% slope should be present.


In many cases we are working to exceed these requirements by providing wider sidewalks on streets that see a high volume of people walking and rolling or by building raised crossings at sidewalk height that make it easier for people using wheelchairs or other mobility devices to cross.

Tufts Street – Paving and Raised Crossing Construction

Crews on Tufts Street have been working to remove the top layers of existing asphalt in advance of paving expected to take place this upcoming Tuesday, July 14, between 7 a.m. and 4 p.m. City contractors plan to pave a preliminary leveling course of asphalt on Tufts Street.  


This is the first of the two paving operations planned for Tufts Street during which an initial course of asphalt will be added to the roadway.

A new large sidewalk bumpout is seen in front of a green building. A street Tufts Street sign is on a poll in the sidewalk.

Following paving, crews will build raised crossings at the intersections of Tufts Street and Cross Street, Dell Street, and Glen Street.  


These steps, along with the installing of new signage and pavement markings, are among the final pieces of this project—converting Tufts Street into a Neighborway.

What is a Neighborway?


Neighborways are low-stress, walk- and bike-friendly residential streets. These streets are designed to lower volume and speeds for vehicles with measures like speed humps or narrowing the entrance to the street to discourage people using the street as a cut through. 


They provide a two-way connection for people biking even if the street is one-way for vehicular traffic.


Learn more about Neighborways in Somerville.

Complete Streets on the Horizon

(West Broadway and Western Pearl)

Complete Streets projects consist of the wholesale reconstruction of major travel corridors to improve safety and accessibility for all users of the road.  


If you’ve traveled along Washington Street between Webster Avenue and the Cambridge City line anytime since late 2024 you’ve seen what this looks like.  


Our next two Complete Streets projects are expected to get underway later this summer:

Water Utility Work Continues in East Somerville

Ensuring water mains remain in good working order is essential to the City’s ability to deliver clean water to residents and to ensuring that enough water is available at any given time for effective fire suppression.

An open trench (dug up portion of the street) is seen with construction workers standing above it and a new pipe being put into the ground.

Work to update water utilities began in East Somerville last fall and is currently ongoing on:


  • Pennsylvania Avenue
  • Everett Avenue
  • Brook Street 


Learn more about this work and see a full map of locations on the project website below.


Residents of affected streets will receive additional notification prior to work taking place.

Subterranean Somerville:

What is a geotechnical investigation?

What is Subterranean Somerville?

Ever wonder what's under your feet when you cross Broadway to get to Foss Park? Or why we've been doing so much digging in Spring Hill?


Each month we'll use this space to highlight a different element of the world beneath our streetsthe old, the new, and what it all means for the future of our city.

Have you ever seen our contractors drilling in a neighborhood where work otherwise may not be taking place? It's possible they are performing geotechnical investigations.


By drilling into the soil/rock at select locations, our teams are able to collect samples that provide information about the character of the underlying soil/rock.


The information gathered helps inform the design of the city’s infrastructure from major stormwater management improvements to new school buildings.

Speaking of which, the City's school building project team recently performed a geotechnical investigation at 115 Sycamore Street to help inform design work on Somerville's next new school building.

Two workers attend to a large drilling machine outside the former Winter Hill School Building at 115 Sycamore Street
