(Wayne County, IN)--A semi loaded with Hershey’s chocolate caught fire on I-70 late Tuesday afternoon.  The semi became fully engulfed in the eastbound lanes near the Williamsburg Pike exit and forced their closure.  Eastbound traffic then backed up well into Henry County.  Alternative routes like State Route 38 and U.S. 40 also became clogged.  County roads then also became backed up due to U.S. 40’s closure with the bridge out near Centerville.  The interstate was closed for several hours.  There were no initial reports of any injury.
