Took in an unusual response in Chicago on the outbound JFK Expressway at Kimball. A semi truck struck the retaining wall and went over the side on an elevated portion of the roadway. The cab detached from the frame (which remained dangling over the lower roadway) and fell to the street below. The driver was reported as being pinned with both portions of the wreckage on fire.
The driver had been removed and was enroute to the hospital when I arrived. Reportedly he was not pinned, but as you might imagine seriously injured. I observed some of the recovery operations utilizing the large IDOT wrecker as well as a bit of the Lin-Mar wrecker operations. A haz mat response was also utilized due to leaking fuel and fluids on both the upper and lower portions of the incident.
