CRESCO, Iowa (AP) — A man accused of driving a 30-ton (30.48-metric ton) grain truck over a small county bridge with a 3-ton weight limit, leading to its collapse, has been cited. Cedar Rapids television station KCRG reports that the truck’s driver was cited for violating a weight embargo.

The collapse happened early the morning of May 5 on Cattle Creek Road over the Upper Iowa River east of Cresco. Officials say the bridge was designed to hold no more than the weight of an average pickup truck, and a sign warning of the span’s limit was clearly posted. Officials say the loaded grain truck caused it to buckle and collapse. No one was injured.

Officials say the river is back open to canoers, kayakers and other rafters.
