Notes:

• Temporary Aerobus installtion for the 1975 Bundesgartenschau (Federal Horticulture Exposition). The system included several suspension spans. It's not clear exactly how many, but the coordinates provided here are the location of a long suspended span over the Neckar next to the Kurpfalzbrücke.
• See 1975 Aerobus - Mont Sainte-Anne, Beaupré, Quebec, Canada.
