The bridge may be stiffened by the addition of cables that do not bear the primary structural or live loads and so may be relatively light. These also add stability in wind. An example is the 220-meter-long (720 ft) bridge across the river Drac at Lac de Monteynard-Avignonet: this bridge has stabilizing cables below and to the side of the deck.

A swing bridge (or swing span bridge) is a movable bridge that can be rotated horizontally around a vertical axis. It has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right.
From west to east, the three spans include: A Warren deck truss (101 ft long), a Pennsylvania through truss (327 ft long and one of the longest in the state [3]), and a swing span (461 ft long). [6] Together they bring the total length of the swing bridge to 889 ft. [ 10 ] [ 9 ] The stone-block piers and abutments are built on timber pilings .
The floor of the bridge consists of a number of 19-foot-wide (5.8 m) transoms that run across the bridge, with 10-foot-long (3.0 m) stringers running between them, and over the top of the transoms, forming a square. [3] Transoms rest on the lower chord of the panels, and clamps hold them together.
