I was stuck on the 5 for a little over two hours last night due to this. I managed to arrive in the area soon after the accident. In fact, I was a little over 1 mile from my exit (Roxford) parked with my car off trying not to fall asleep. I witnessed countless emergency response vehicles trying to maneuver through the mess of cars on the 5 and 405 merger. They had us all divert off at Roxford, which was fortunate for me as it was my exit and I was out of gas.
