An Aroostook County woman died Tuesday after the pickup she was driving went off the interstate in New Hampshire and crashed into a tree.

New Hampshire State Police were called to the accident on I-89 in Sutton just before noontime.

Troopers said the Ford F-250 pickup truck was northbound in the left lane when it drifted off the left side of the highway and into the median. The vehicle then struck a tree on the driver's side.

The driver, 64-year-old Sarah Grier of Woodland, Maine was pronounced dead at the scene. A female passenger sustained critical injuries and was airlifted to Dartmouth-Hitchcock Medical Center in Lebanon, NH.

Interstate 89 was shut down for several hours Tuesday afternoon while police attended the scene.

The cause of the crash remains under investigation.
