LONDONDERRY — One man was airlifted to a Boston hospital after he crashed his car into a guard rail on Interstate 93 Sunday afternoon.

Philip Couture, 27, of Bow, was driving his 2004 Kia Optima south on the highway around noon when his car drifted into the breakdown lane and hit the guardrail, according to New Hampshire state police.

Coture was taken by helicopter to a hospital in Boston while his passengers, Sara Cybulski, 21, of Concord, and a 2-year-old girl were taken to the Parkland Medical Center. Speed and alcohol do not appear to be factors in the crash, and it is still under investigation.

The highway was closed temporarily for the helicopter to land. Anyone with information about the crash is asked to contact Trooper Jeffrey Tenczar at 271-1154.
