Southbound I-55 approaching US-52 has all lanes back open again after an earlier crash.
The accident on SB I-55 in Joliet involved 3 cars; 1 car into the wall, 1 car flipped the wrong-way and another car slid off into a nearby ditch.
All lanes were completely blocked early Thursday causing a major back up. Some traffic was getting by on the shoulder.
Delays have much improved since earlier.
