Construction of the Chicago Transit Authority orange line rapid transit to Midway Airport. Chicago Illinois. May 1989., a photo by Eddie from Chicago on Flickr.
Looking west from South Kostner Avenue, we see the concrete supports for the then under construction, Chicago Transit Authority orange line rapid transit, being built on site near adjacent 55th Street Junction along the Belt Railway of Chicago tracks.
This is one of those behind the scenes random reference photographs I had taken, for future generations to enjoy.
