I was surprised to find no single-sheet origami suspension bridges other than Jeremy Shafer's Dollar-bill Golden Gate Bridge, so I tried designing my own. The model requires a 2x1 rectangle and is based on a 36x18 grid. For a first fold, I would recommend a sheet at least 12" x 6" (30cm x 15cm). This results in a folded model size (height x length x width) 2" x 7" x 1" (5cm x 17cm x 2cm) with the smallest features being about 1/4" (5mm) wide pleats. If you are not comfortable folding narrow pleats, it would be a good idea to start with a larger sheet.

Bibliography

This model has not been published. I designed it just this past week. I am working on diagrams and plan on submitting them to the PCOC 2021 diagram book.

Supplies

One 2x1 rectangle of paper, at least 12" x 6" (30cm x 15cm). Foil is a good choice if available at that size. I plan to guide the class through folding a 36 x 18 grid, using the approximate division into thirds (twice).
