New Traffic Signal Activated

New traffic signal equipment at the intersection of Alewife Brook Parkway and Powder House Boulevard has been activated, marking a significant milestone in the intersection redesign project.

Initial Temporary Signal Configuration

Following activation, there will be an approximately two week period where signals are in a temporary configuration.

• Flashing yellow to traffic approaching from Alewife Brook Pkwy.
  • Indicates people driving should proceed with caution
• Flashing red to traffic approaching from Powder House Blvd.
  • Indicates people driving should come to a complete stop before proceeding when it is safe to do so
• The current signalization crosswalk across Alewife Brook Parkway to the west of the intersection will remain in place throughout this period.
  • New pedestrian signals/crossing will not be turned on/active during this temporary configuration.

Regular Signal Configuration

Following the approximately 2 week temporary configuration, signal equipment will be switched to its regular (green, yellow, red) configuration.

• At this stage, pedestrian signals will be turned on and new crossings will be activated.
  • Old signalized crossing across Alewife Brook Pkwy will be deactivated at this stage

Please observe all signals/signage and proceed with caution while navigating through the intersection.
