The Wisconsin State Patrol says a man died when he crashed his motorcycle on I-39 southbound at exit 142 to U.S. 12 Thursday evening.
Authorities say an object fell off a truck/trailer and a second vehicle hit the object projecting it into the motorcycle. The impact caused the rider to veer off the road and hit a sign. The man then was ejected from the motorcycle as it flipped.
He was later pronounced dead at UW-Hospital. The victim's name has not been released yet.
