A tractor trailer crash on I-91 north in Rocky Hill left one driver hurt and several first responders in need of treatment.
Three lanes of the highway were back open after being closed for the first part of the morning commute.
According to State police, the vehicle went off the road around 3 a.m. north of the exit 23 off-ramp in Rocky Hill Friday morning.
When the Rocky Hill Fire Department arrived, firefighters said they found the tractor trailer about 100 feet off the road. It had a large tree.
The driver was heavily entrapped inside and severely injured.
Due to the extent of the injuries, firefighters said they anticipated the extraction process to be lengthy.
The Life Star emergency helicopter was called to the scene and landed on the highway to transport the driver to a hospital.
Crews said it took them two hours to get the driver out.
Several first responders were treated for heat-related complications, according to firefighters. They have since been released.
The cause of the crash remains under investigation.
There are still heavy delays on I-91. The tractor trailer was removed around 3:45 p.m.
