I very recently obtained some diagrams from 1970 that showed how PIT would look like by 2000. Very interesting how they envisioned the airport.
I figured I'd share them now since there is absolutely nothing else good to talk about. Click on image to enlarge
- On the airport diagram what appears to be 10C/28C is actually present day 10R/28L, and a new 10R/28L would be built to the immediate south. This would have provided a wider area to build the midfield terminal.
- What is 10C/28C today (the original 10/28, then relabeled 10R/28L when 10L/28R was built) was to have its western 2/3 eliminated, leaving the eastern section available as a general aviation runway of about 3,500' long.
- Note the V/STOL port in the area currently known as "Neighborhood 91" with two runways about 1,500' long.
- Total of 9 runways, including the GA and STOL runways
- The Beaver Valley Expressway was to be extended around the old terminal as depicted. There were plans to remove the traffic light at I-376B and University Blvd to sort of follow through with this concept up until fairly recently but they just completed a new strip mall where part of this interchange would have gone.
- Note the huge ramp and service road on the west side of the new 14/32 runways. This undoubtedly would have served to anchor some sort of aeronautical/industrial complex, the lack of which I was just grumbling about recently.
All in all very interesting plans! Amazing these are 50 years old. Very grandiose with putting the airport expressway under 10L/28R, structured parking below the main terminal, 4 separate APM lines, and all those satellite concourses. It wouldn't have worked well for hubbing operations but as the airport transitions its facilities to cater to O&D all they would have needed to do is extend the two middle satellites westward to meet the main terminal.
