The Brickpit Ring Bridge is supported by 'X' shaped piers and cables for additional stability. A ring connects the substructure to the superstructure elements. The superstructure includes cross-braces, more cables, a steel deck, and panels to protect visitors from the elements.
A bridge in the shape of a ring is unusual and stretches the limits of what is a bridge. I recall that the Happy Pontist mentioned a similar bridge that carries visitors over the plants in Kew Gardens.
