GLADSTONE, N.D. (AP) — A hay bale fire on a semitrailer shut down a portion of Interstate 94 in southwestern North Dakota for about four hours.

The Highway Patrol says the bales on the semi started on fire Tuesday 3 miles east of Gladstone. The driver was able to disconnect his cab from the trailers and wasn't hurt.

The westbound lanes of the interstate were closed at the Taylor exit, and traffic was rerouted until the fire was out and the scene cleared.
