Traffic on southbound I-39/90 is backed up for several hours due to a traffic accident Monday evening.
The Wisconsin State Patrol says the two-vehicle crash was reported just before 7:00 on the Highway 26 overpass bridge.
First responders found a semitrailer flipped onto it's side, leaking diesel fuel.
The driver of the semi was transported to a local hospital for minor treatment.
The southbound on-ramp to the interstate from Milton Avenue and the left lane of southbound I-39/90 were closed for more than two hours while crews worked to clear the scene.
