The pileup took place on a bridge that was shrouded in heavy morning fog, which caused multiple vehicles to crash, according to state-owned The Global Times.
Photos from the scene show the long multi-lane bridge, stretching across fields and the Yellow River, strewn with vehicles crammed into each other. Cars, cargo trucks, lorries and other vehicles can be seen in the pileup.
CNN reports in videos filmed from the ground, the air is still thick with fog. One clip shows a truck sliding forward, crashing into several smaller cars, as sirens ring in the distance.
