Drivers should take care to pay attention to all signage and move carefully through the work zone. Police details, lane markings, temporary barriers, traffic cones, signage, and other tools will be used to control traffic and create safe work zones.

The contractors are coordinating with local event organizers and police to provide awareness and manage traffic during events. For your awareness, there will be no events at the TD Garden during this look ahead schedule.
