4 Hurt In Route 3-Closing Crash

TYNGSBORO, MA — A wreck on Route 3 South shut down the entire highway Sunday night, with four being sent to the hospital, police said.

The crash occurred around 8:05 p.m. just north of Exit 34. Police said a 2016 Jeep Grand Cherokee traveled off the right side of the road and struck a large sign post. It appears "operator fatigue" was a factor, police said.

The driver was airlifted to Beth Israel Hospital in Boston with serious injuries. The three passengers went to Lowell General Hospital with minor injuries.

Both sides of the highway were temporarily closed while the helicopter landed.

State and local police from Tyngsboro and Chelmsford responded.
