Completed in 1894, the side-spans of this bridge represent a rare example of a three-hinged suspension bridge where the tension member itself is stiffened by being designed as a truss. A determinate system, similar to the three-hinged arch. For center span of Tower bridge, see also GoddenD27. (London, England)
