A Belle Fourche man was killed early Monday in a one-vehicle crash on Interstate 90 in Lawrence County.

The Highway Patrol says 35-year-old Greg Alan Baier was westbound just after midnight when his pickup went off the road near the Spearfish Exit at Mile Marker 10.

The vehicle struck a snow gate and overturned, coming to rest on its wheels between the westbound driving lanes and the off-ramp.

Baier was not wearing a seat belt and was thrown from his vehicle.

He died at the scene.
