As of November 2020, the project is currently in the conceptual design phase. Final design is expected to be complete by Winter 2021, followed by bidding and construction which will tentatively last through 2023.

    Thank you for attending the first public meeting last November, filling out the survey, and sharing your priorities for an improved intersection. Based on the feedback we received and shared goals by residents and the City to create significantly safer pedestrian and bicycle connections at this intersection, we are moving ahead with the signalized intersection concept. The updated concept will be further defined as project design progresses. The exact placement of sidewalks, bike lanes, and other traffic calming elements will be reviewed by City staff as well as our partners at the Department of Conservation and Recreation. There will also be additional opportunities for resident input, so please continue to check this page for updates. The improved concept maximizes green space, reduces the crossing distance for pedestrians and bicyclists, and incorporates raised bike lanes on Powderhouse Boulevard from North Street to Alewife Brook Parkway. We are excited for these transformational changes!
