On November 21, 2018, a bridge collapse near Hurley, Wisconsin, resulted in injuring 3 workers.

The cause of the collapse was a support bar failure at the time that the workers were pouring concrete in a reinforcing bar. 2 out of the 3 injured men suffered minor damage but the third one sustained a leg and an eye injury as concrete contacted his eye. Fortunately, all of them were released from the hospital a day after the accident.

The bridge, with a height of about 3,5 meters, was located east of the Highway 18 and 454th Avenue intersection and was under construction at the time of the collapse.

The construction of the bridge was conducted by Grangaard, a company that is now cooperating with South Dakota Department of Transportation to evaluate the possibility of demolishing and building the deck of the bridge from scratch. The Department of Transportation considers redirecting the traffic around the bridge during the winter.

A meticulous investigation about the causes of the support bar failure is being carried out by the Occupational Safety and Health Administration (OSHA) and will last for about 6 months. During preliminary research, it was found that Grangaard failed to install fall protection at an Interstate 29 job site in 2017 and was fined for about $6,500.
