A semi-trailer full of grain came loose and crashed on US Highway 20 near Rigby on Wednesday.

The semi was pulling two trailers, when all of a sudden the second trailer unhitched and plowed into the side of the road.

Some 20 to 30,000 pounds of wheat was dumped on the side of the highway, causing a big mess.

Luckily no other vehicles were involved in the mishap.

The truck was from a farm in Ashton.
