On April 1st, 2023 at approximately 3:45 CT a John Deere 9650 combine was traveling west on
I-94, from Mandan to Glen Ullin, ND. The combine did not have a header attached and had
been traveling on the right shoulder. A Kenworth truck-tractor, hauling diesel fuel, was also
traveling west on I-94 from Mandan, heading to Richardton, ND. As the combine approached
the 41st Avenue overpass, the driver drove into both lanes to cross the bridge. The semi driver
applied the brakes and attempted to evade by steering but was unable to avoid a collision
with the rear of the combine. The combine spun laterally to the left. Both units came to rest
with the semi facing west with the combine interlocked with it facing south on the bridge. No
hazardous materials were released. No serious injuries were reported or observed. The
roadway was not passable by traffic at the bridge. Traffic was rerouted, in the westbound lane
only, at exit 134 to Highway 10 to New Salem for approximately 2 hours and 38 minutes. This
crash is under investigation by the North Dakota Highway Patrol.
