Terenez bridge cable-stayed bridges actually are very different from suspension bridges in principles and method of construction. In a suspension bridge, the long cables are the primary load-bearing structures that are mainly responsible for the function of the bridge; for a cable-stayed bridge, the pylons form the primary load-bearing structures. For a bridge span of medium length, like that of Terenez Bridge, a cable-stayed design is optimal from both structural and economic perspectives. Since the cables of Terenez Bridge will not be exerting large horizontal tensile forces on the anchorages, construction of the bridge does not require excellent soil conditions. The deck
Pontoon bridge points. The "Palsey Pontoon" lasted until 1836 when it was replaced by the "Blanshard Pontoon" which comprised tin cylinders 3 feet wide and 22 feet long, placed 11 foot apart, making the pontoon very buoyant. The pontoon was tested with the Palsey Pontoon on the Medway. An alternative proposed by Charles Pasley comprised two copper canoes, each 2 foot 8 inches wide and 22 foot long and coming in two sections which were fastened side by side to make a double canoe raft. Copper was used in preference to fast-corroding tin. Lashed at 10 foot centres, these were good for
