Intersection Redesign: Powder House Boulevard and Alewife Brook Parkway

The City of Somerville is reconstructing the intersection of Alewife Brook Parkway and Powder House Boulevard with support from a MassWorks Infrastructure Program grant. The project will create safer roadway conditions for all users and upgrade aging underground infrastructure.

Construction is expected to begin in late December/early January and continue through the fall of 2024.

Why is this intersection being reconstructed?

The current intersection is a high crash location (48 crashes between 2014-21). Focusing our efforts on the intersections where the greatest number of crashes occur is part of the City's Vision Zero Action Plan for reducing and eliminating transportation injuries and fatalities.

What are the goals of this project?

The goals of the project are to improve safety for everyone traveling along the road by enhancing pedestrian and bicycle connections, improving access for residents, and slowing drivers. The project design also seeks to add green space and retain trees.

Interested in learning more?

On February 1 the City will host a community meeting to review the final design, discuss the construction process, and field questions from the community.
