The Ordish–Lefeuvre system, or Ordish–Lefeuvre principle, is an early form of cable-stayed bridge design, patented by Rowland Mason Ordish and in 1858. The Ordish–Lefeuvre system differs from conventional suspension bridges in that, while as with a conventional suspension bridge a parabolic cable supports the centre of the bridge, inclined stays support the remainder of the bridge's load. Each stay consists of a flat wrought iron bar attached to the bridge deck, and a wire rope connects the wrought iron bar to one of four octagonal support columns.
