A Pennsylvania man died Friday in a car crash on Interstate 93 near the Basin in Franconia Notch in Lincoln.
Steven Schwartz, 23, of Philadelphia, Penn., was pronounced dead at the scene, but his pit bull puppy survived, police said.
Schwartz was driving north on I-93 at about 7 a.m. when his Hyundai Elantra collided with a tractor-trailer driven by James Spring, 54, of Warren, Mass., state police said.
A preliminary investigation found that Schwartz, who was not wearing his seatbelt, drove directly into the back of the tractor-trailer and then struck a guardrail on the left side of the highway. Both vehicles were traveling in the right lane.
State police said speed was a factor in causing the crash. The speed limit in that area of Franconia Notch is 45 mph, and that it is common for trucks to travel slower than the posted speed limit in order to ascend an incline in the road.
