A van crashed into the back of a semi-truck near Harlem on the Stevenson Expressway Friday during the evening rush hour.

The crash caused major delays on the expressway. At one point the trip from Lake Shore Drive to the tri-state was more than two hours.

Traffic was still backed up well into Friday evening.
