    I don’t think this is a suspension bridge, I can’t see any suspension and the caption says “swing bridge”

        Huh, apparently it is a “simple suspension bridge”, which when I click gives:

        Not to be confused with Suspension bridge or Swing bridge.

        These bridge people need to sort out their naming schemes!

          Makes sense, historically.

          A suspension bridge is one in which the primary structural element is formed by ropes or cables which are suspended across a gap in a hanging arc.

          In the simplest form of that bridge, the deck is directly attached to the wires and follows the same arc, like here.

          The bridge most of us think of as a “suspension bridge” is the “suspended deck suspension bridge” in which the deck is also suspended, by more cables, below the primary suspension. So there’s two independent suspensions going on there.

          But in all cases the bit that makes it a suspension bridge is the main structural cable.
