Alewife Brook Pkwy/Powder House Blvd Intersection - New Traffic Pattern, Begins 7/25 or Soon After

Beginning on Tuesday, July 25 or soon after, City contractors will install a 3-way stop at the intersection of Alewife Brook Parkway and Powder House Boulevard as part of the City’s intersection redesign project.

New Traffic Pattern

City contractors are in the process of reconstructing the existing traffic circle to create a T-shaped intersection.

  • Stop signs will be installed in all three directions, while awaiting the installation and electrification of new traffic signal equipment.

    • Video message boards and signage along Alewife Brook Parkway will be in place to inform driveways of the new pattern.

    • Traffic along Alewife Brook Parkway in both directions will be reduced to one lane approaching the intersection.

    • Orange construction barrels along work zones will be in place along workzones.

  • This new traffic pattern will also create a new shared street between 269 and 294 Alewife Brook Parkway.

    • A shared street is a low-volume residential street that prioritizes people walking, rolling, and biking.

    • This street is intended for residents/emergency vehicles only and is not a thruway.

Pedestrian Access

The current signalized crosswalk across Alewife Brook Parkway to the west of the intersection will remain in place throughout construction.
