Stamford — A New York man was seriously injured after hitting a tractor-trailer head-on while driving the wrong-way on Interstate 95 that closed the highway for hours Friday morning, Connecticut State Police said.

A tractor-trailer was traveling southbound near Exit 7 around 2:30 a.m. Friday when it was struck by a 2016 Ford Edge, which was driving north on the wrong side of the highway, State Trooper Nicolas Falstoe said Saturday.

Falstoe identified the wrong-way driver as Edgar Alvarracinvizhco, 27, of Port Chester, N.Y. Falstoe said he was transported to the hospital with serious injuries.

The man was not using a seatbelt at the time of the crash, according to Falstoe's report.

The driver of the tractor-trailer and his two passengers were not injured, Falstoe said.

The crash closed the southbound lanes of the highway for about six hours and backed up traffic for miles. The crash remains under investigation, Falstoe said.

Any witnesses to the crash can contact Falstoe at 203-696-2500 or nicolas.falstoe@ct.gov. Police also asked for assistance from anyone who drove through the area of the collision at the time of the crash and may have footage recorded on a dashboard camera.
