June 2024 - Midsummer Construction Update

Welcome back to the City of Somerville's construction newsletter!

Summer is in full swing. People are heading to the beaches or the now open for the season Dilboy Pool, the Fourth of July is right around the corner, and we're going to need a bigger email to highlight all the work going on around Somerville to maintain and improve our City's infrastructure. 


What We're Sharing This Month: 


  • Highland Avenue Partial Paving - Coming (Very) Soon
  • Final Paving at Alewife Brook Pwky and Powder House Blvd
  • Glen and Otis Street Neighborway Implementation
  • A Summer of Streetscape Improvements on Spring Hill 
  • Continued Progress (and Cobbles) on Western Washington
  • Subterranean Somerville: 40-ft Below Poplar Street

Highland Avenue Partial Paving

Following critical underground infrastructure work (installation of new sewer, drainage, water, and gas utilities), crews have begun preparing to pave Highland Avenue.


City contractors from our Spring Hill Sewer Separation Project will be paving the two travel lanes of the roadway (approximately 28-feet wide) along Highland Avenue between McGrath Highway and Benton Road.

Contractors will be paving this segment of Highland Avenue in two mobilizations.


  • Mobilization 1 - Highland Avenue between McGrath Highway and School Street
  • Mobilization 2 - Highland Avenue between School Street and Benton Road


This partial paving, which does not include the parking areas next to the curbs, is intended to restore the road surface travel areas. This is an interim measure to support safe travel for all users of the road until the full redesign and reconstruction of Highland Avenue.


Paving is expected to take place mid-July. Once a date is finalized, we look forward to sharing those plans with the community.

Powder House Boulevard and Alewife Brook Parkway Intersection Redesign 


Final Paving and Remaining Work

After a necessary reschedule (ok, two), final paving at the City’s newest T-shaped intersection is here and is expected to be completed by this upcoming Monday, 7/1. This paving includes includes: 


  • The intersection of Alewife Brook Parkway and Powder House Blvd. - extending roughly 600 feet in either direction along Alewife Brook Parkway
  • Powder House Blvd between North Street and Alewife Brook Parkway
  • Powder House Blvd and North Street intersection
  • The new residential shared street along Alewife Brook Parkway

Final roadway striping will follow shortly after paving. Other remaining work, including new tree plantings will follow ahead of expected substantial project complete this summer.

Glen and Otis Street Neighborway Implementation 

New, recently painted murals at the East Somerville Community School aren’t the only change coming to the neighborhood.

If you haven’t heard, Somerville is partnering with CultureHouse and Neighborways Design to create a Neighborway on Glen Street in East Somerville between Tufts Street and Broadway, and on Otis Street between McGrath Highway and the East Somerville Community School. 

As defined in the Somerville Bicycle Network Plan, “Neighborways” are walk-, roll-, and-bike friendly streets that create a low-stress and high comfort experience on residential streets.

What's happening? Where and When?


As early as next week, City contractors will begin installing the new signage and pavement markings associated with this change. Following this work, Glen Street will become a two-way street for bicycles (while remaining one-way for vehicles).

Continued Progress on Western Washington Street

Work is progressing on the City’s effort to reconstruct western Washington Street. The new design will make traveling along the street safer and more comfortable for people walking, wheeling, biking, taking the bus, or driving. 


Crews have been rebuilding sidewalks on the southern/even-numbered side of the street. Work has been proceeding east from Beacon Street toward Webster Avenue. On sections of the street where we are building a sidewalk-level bike lane, crews have been installing a cobble buffer between the sidewalk and bike facility as seen in the image below. 

Visit our project website to review the full design and stay up to date as work progresses.

Spring Hill Sewer Separation

Summer of Streetscape Work 

In addition to upcoming paving on Highland Avenue (McGrath to Benton Rd.), there is a lot happening on Spring Hill as crews work to upgrade streetscapes throughout the project area:

School Street - Crews are finishing installation of new sidewalks and traffic calming bump outs along the western side of the street. Sidewalk installation is expected to be completed within the next 3-4 weeks. Final paving on School Street is expected to take place later this year.

Central Street - In case you missed it, Central Street is now one way northbound heading from Summer Street toward Highland Avenue. Crews have paved an initial binder course of asphalt and will begin building new sidewalks and protected cycle tracks on both sides of the street in the coming weeks.

Summer Street - Crews are finalizing installation of an in-ground irrigation system to support newly planted trees. Following completion of this work, crews will add a top layer of asphalt to the new westbound bike lane. Final paving of the roadway will follow later this year. 



Meanwhile the final underground utility installations of the project are underway on lower Summer Street (Bow Street to School Street).

Subterranean Somerville:

40-feet Below Poplar Street

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 streets—the old, the new, and what it all means for the future of our city.

What does the underground home of a stormwater tank with the capacity to store up to 4 million gallons of stormwater look like? Well it looks like the 40-foot-deep, 170-foot-wide hole pictured below.


Following excavation, crews have been working to prepare the site for the tank’s installation by creating a level surface and installing anchors that will link the tank with underlying bedrock among other efforts. Next up, crews will pour the 1200+ cubic yard concrete slab that will serve as the tank’s base.

Why are we doing all this? Once activated, the Poplar Street pump station and the accompanying underground storage tank will fundamentally change the way stormwater drainage is managed for approximately 60% of the city. It represents a major investment in modernizing the City’ stormwater management infrastructure and increasing preparedness for extreme weather events.
