I-95 northbound was closed for several hours Tuesday morning between exits 8 and 9 in Stamford due to a crash that caused injuries, the Connecticut Department of Transportation says.

Connecticut State Police say they responded to the area of exit 10 around 10:56 a.m.

The Stamford Fire Department said multiple vehicles were involved including passenger cars, a dump truck and a tractor-trailer. They also said more than 40 firefighters from Stamford and Greenwich worked for over an hour to free the driver of the dump truck.

The dump truck was significantly damaged in the crash after coming in contact with the rear of the tractor-trailer. The driver was pinned inside the truck, resulting in an extended extrication. Officials said the individual was conscious throughout the rescue and was taken to Stamford Hospital for treatment.

Two other people involved in the crash sustained minor injuries. State police are investigating the incident.

The exits were closed around 11 a.m. All lanes reopened shortly after 2 p.m.

Multiple vehicles were involved in the crash. Heavy traffic was also reported between exits 3 and 9.
