Marlborough, MA (August 12, 2026) – Two people died on Monday afternoon, August 10, after a collision on I-290 eastbound in Marlborough. Both were ejected from a white SUV involved in the wreck, according to the Marlborough Fire battalion chief.
A second vehicle, a black SUV, came to rest among trees in the median. One person from that vehicle was taken to a hospital with injuries. Debris that appeared to be paper was scattered across the roadway, while one lane in the opposite direction was also closed for emergency units.
Two dogs were inside the white SUV. One was taken to an animal hospital for injuries, while the other was unharmed and placed with Marlborough Animal Control. Traffic remained disrupted for several hours before I-290 reopened shortly after 7 p.m. The cause of the fatal collision remains under investigation as additional details are reviewed.
Our deepest condolences go to the families and loved ones of those who died.
What Can Be Examined After a Serious Highway Collision?
Investigators may examine several types of evidence after a serious roadway collision. Vehicle damage can help show where and how forces were applied during the contact between vehicles. Photos, debris patterns, and pavement markings may also provide useful information about vehicle movement.
Witness accounts can help establish what drivers were doing before the vehicles came together. Investigators may also review roadway design, lighting, weather, and traffic conditions at the time.
Medical records can provide information about the severity of injuries and treatment received. In cases involving fatalities, additional records may help establish the circumstances surrounding each death. Vehicle data systems, when available, can sometimes provide information about speed, braking, steering, or other actions shortly before a major roadway collision.
