Bucket truck topples onto Memorial Drive traffic in Cambridge, leaving worker seriously injured and roadway closed
Incident shuts down a major Cambridge riverfront artery during the morning commute
A worker was seriously injured Wednesday morning, March 4, 2026, after a bucket truck tipped over into traffic on Memorial Drive in Cambridge, prompting a full shutdown of a busy section of the state-managed parkway and an ongoing investigation by authorities.
Massachusetts State Police said troopers responded to reports that a bucket truck had been knocked over into oncoming traffic on Memorial Drive. The worker who was injured was in the truck’s elevated bucket at the time of the incident and was transported to a medical facility for treatment. The worker’s name and employer were not released, and officials had not provided an updated condition by late morning.
Location, emergency response, and immediate traffic impacts
The incident occurred near Harvard Square, in the area in front of the Charles Hotel, where troopers from the State Police Boston Barracks responded alongside Cambridge Fire and emergency medical crews. Video from the scene showed the truck resting on its side, with the boom and basket extending into the roadway and blocking travel lanes. A heavy-duty tow truck was brought in to assist with recovery.
At least one passing vehicle was damaged in the incident, and a driver at the scene said their Toyota RAV4 was struck by the bucket truck. Authorities did not report additional injuries at the scene.
- Roadway affected: Memorial Drive in Cambridge
- Closure area: from North Harvard Street to JFK Street
- Expected duration: authorities warned the shutdown could last several hours
What is known about the work being performed
Officials indicated the bucket truck appeared to be conducting tree work when it toppled. Investigators had not publicly detailed the sequence of events that led to the truck overturning, including whether the incident involved contact with another vehicle, a shift in ground conditions, equipment failure, or other factors.
The investigation remained active Wednesday, with police and fire personnel observed documenting the scene and gathering evidence before the truck was uprighted and removed.
What remains unclear as investigators examine the cause
As of Wednesday morning, authorities had not released information on the worker’s exact injuries, whether safety systems in the bucket were engaged at the moment of the tip-over, or the specific conditions that contributed to the loss of stability. Officials also had not said when the affected stretch of Memorial Drive would reopen.
Memorial Drive is overseen by the Massachusetts Department of Conservation and Recreation, and closures on the roadway can create significant ripple effects for local traffic patterns given its role as a primary east-west corridor along the Charles River.
