I don't think they are that old. I remember them being installed in the early to mid 2000's, when they did some work on that stretch of the Kennedy. They removed several left hand side on-ramps, as well as added the red railings with the stars from the Chicago flag in the metalwork.

I remember with some fondness the 300-500 feet given for cars to either merge or die when getting on 90/94. They were particularly rough during rush hour.
