Old Lyme — Interstate 95 northbound lanes and one southbound lane are open around Exit 70 after separate accidents occurred there earlier Saturday morning. 

A second accident involved multiple vehicles and resulted in at least one fatality, according to Connecticut State Police Trooper First Class Kelly Grant.

As of 10:15 p.m., state police Troop F reported that only one southbound lane was open, as crews worked to repair the damaged guardrail. The northbound lanes of I-95 in the area of that exit reopened by 2:15 p.m.

The first crash — involving only one vehicle, a tractor-trailer — occurred around 4:30 a.m. Saturday on the southbound side approximately one mile north of Exit 70.

For an unknown reason, the vehicle, owned by Cottrell Truck Lines Inc., traveled into the right shoulder, state police said, colliding with a guardrail and then into a concrete bridge support.

The driver, Arturo Paez, 62, of Stratford, was transported via Life Star helicopter to Yale-New Haven Hospital for treatment of his injuries. The remains of the cab of a tractor-trailer could be seen near the Whippoorwill Road Overpass.

The second crash with at least one fatality occurred on the northbound side around 5:30 a.m., according to Grant, public information officer for the state police. The name of the victim was not released. Others were injured, Grant said. The accident involved at least five cars and two tractor-trailers. At least three cars piled up on top of each other were visible on the northbound side.

The state Department of Transportation, Department of Consumer Protection and the Department of Energy and Environmental Protection responded for cleanup management.

On its website, the state DOT provides various I-95 traffic camera views, which drivers can use to monitor traffic in a specific area. Motorists can also check the state's interactive travel map for updated traffic information.
