The Union Terminal Concourse under demolition in 1974, looking northeast. The area in the center, behind the wrecking crane, is the portion of the concourse from the last photo. The low clearances can be seen at the bottom left. The steel beams marching up the left side of the photo are from one of the platform canopies. Note that the connection between the concourse and the main headhouse has already been patched up. Tower A can be seen at the top right.
