(Lodi) Authorities in Columbia County say the county highway department worker who was injured during an accident on the interstate is in stable condition and anticipated to make a full recovery. It all started Friday morning around 4am in the northbound lanes of Interstate 39 near Lodi. The Wisconsin State Patrol says it all began when one semi rear-ended another semi. About an hour later, a pickup truck traveling at highway speed hit a State Patrol cruiser stopped at the scene. Two state troopers and the highway worker were injured by flying debris. With traffic backed up at 6:45am, a major crash occurred a mile south of the two initial crashes. A semi-tractor traveling at highway speeds created a chain-reaction crash involving at least eight vehicles-three semi-tractor-trailers, a dump truck and four passenger vehicles. Four people were killed and three others seriously injured. Traffic was rerouted for about seven hours.
