A City of Somerville concept plan from 2021 of changes to where Powder House Boulevard meets Alewife Brook Parkway.

The northern entrance to Somerville – Powder House Boulevard at Alewife Brook Parkway – has long been identified as a high-crash location. Now, as part of the the city’s Vision Zero Action Plan to end traffic deaths and serious injuries from transportation, the intersection is getting an overhaul.

Community members will have a chance to learn about the project at a virtual community meeting 6 p.m. Wednesday via the Zoom videoconferencing platform.

Construction is expected to begin this winter and last through the fall of 2024, funded by the state MassWorks Infrastructure Program.

“As we enter the construction phase of this project, we want to provide an opportunity for people to learn more about the intent of this work, the final design and the construction process,” a city spokesperson said Thursday. “This meeting will also provide a space for attendees to ask City staff any questions they may have.”

According to the city, vehicles crashed 48 times between 2014 and 2021 at the Powder House and Alewife Brook intersection. The new design will take the current traffic circle and recast it as a T-shaped intersection with traffic signals; enhance pedestrian and bicycle connections; create a low-volume residential street that prioritizes walking, rolling and biking; and rehabilitate aging underground infrastructure.

At the meeting Wednesday, city staff plans to present project information, including intent and motivation, the scope of the project, a construction timeline and what temporary detours can be expected. There will also be information on tree plantings for when the project finishes, as well as contact information for residents. The final part of the meeting will be a question-and-answer session for attendees with staff.

The city plans to continue holding meetings throughout construction “as one way to keep residents engaged and informed,” the spokesperson said.

Registration for the meeting is here.
