This is interesting but the 5 euros note does not really represent a bridge but an Aqueduct (looking really like this one https://en.wikipedia.org/wiki/Pont_du_Gard https://en.wikipedia.org/wiki/Pont_du_Gard). So you can't really walk on it like they show in their schematic proposal.

What distinguishes it as being an aqueduct rather than a bridge? (Visually, I mean.) Didn't the Romans construct them in very much the same way?

  An aqueduct was a bridge for moving water instead of people.

    Not only "was" but also "is". Here's a list of canal aqueducts in the UK: https://en.wikipedia.org/wiki/List_of_canal_aqueducts_in_the_United_Kingdom https://en.wikipedia.org/wiki/List_of_canal_aqueducts_in_the... The newest aqueduct I saw listed at https://en.wikipedia.org/wiki/Aqueduct_(bridge) https://en.wikipedia.org/wiki/Aqueduct_(bridge) is https://en.wikipedia.org/wiki/Mathur_Aqueduct https://en.wikipedia.org/wiki/Mathur_Aqueduct , which was built in 1966. It's meant for irrigation water .

If you note the sale of the humans on the diagram, it's clear they're schematics of the actual bridges he built, not the theoretical inspiration which would be much larger.

  For some of the bridges, that's OK, but the miniature stayed suspension bridge looks kind of silly.

    You call it silly. I found it extremely funny, and a little thought provoking even.

    Engineer nitpick: it's actually a cable-stayed bridge! Suspension bridges have hanging main cables in an arc between the towers, then the bridge is supported by smaller vertical connectors between the main cables and roadway. https://en.wikipedia.org/wiki/File:Bridge-suspension.svg https://en.wikipedia.org/wiki/File:Bridge-suspension.svg https://en.wikipedia.org/wiki/File:Bridge-fan-cable-stayed.svg https://en.wikipedia.org/wiki/File:Bridge-fan-cable-stayed.s... https://en.wikipedia.org/wiki/Cable-stayed_bridge https://en.wikipedia.org/wiki/Cable-stayed_bridge

      It's supposed to look like a cable-stayed bridge, but it's probably just a beam. The cables seem decorative only. Look at those huge supports underneath. Here's the real thing in a small bridge, the Mary Avenue bike bridge over Interstate 280 in Cupertino.[1] This is a very good looking bridge, and went up fast - only three nights of road closures to assemble the deck.
