Once the main cables are in position, they furnish a stable working base or platform from which the deck and stiffening truss sections can be raised from floating barges or other equipment below, without the need for auxiliary falsework. For the Severn Bridge, for example, 60-ft box-girder

The fundamental difference between these two classes is the manner in which the bridge deck is supported by the cables. In suspension bridges, the deck is supported at relatively short intervals by  vertical suspenders, which, in turn,
