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.
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.
Submersible bridge – also called a ducking bridge, the bridge deck is lowered into the water; Tilt bridge – the bridge deck, which is curved and pivoted at each end, is lifted at an angle; Swing bridge – the bridge deck rotates around a fixed point, usually at the centre, but may resemble a gate in its operation ; road or rail

A contract for the substructure of the bridge was given to American Bridge Company. [6] The pin-connected drawbridge was designed by Alfred P. Boller, an authority on deep bridge foundations, to allow the bridge to pivot/swing, clearing a path for through river travel. [9] The 3 spans of the bridge are all composed of rivet-connecting steel ...

In biochemistry, a Ramachandran plot (also known as a Rama plot, a Ramachandran diagram or a [φ,ψ] plot), originally developed in 1963 by G. N. Ramachandran, C. Ramakrishnan, and V. Sasisekharan, [1] is a way to visualize energetically allowed regions for backbone dihedral angles ( also called as torsional angles , phi and psi angles ) ψ ...
