Design
Pegasus Bridge and the structure that replaced it in 1994 are examples of a distinct subtype of bascule bridge, the "Scherzer rolling lift bascule bridge" or "rolling bridge". Bridges of this type do not pivot about a hinge point, but roll back on curved tread plates attached to the girders of the main span. This design allows a greater clearance of the waterway for a given opening angle.

Famous quotes containing the word design:
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (1613–1680)
“Delay always breeds danger; and to protract a great design is often to ruin it.”
—Miguel De Cervantes (1547–1616)
“We find that Good and Evil happen alike to all Men on this Side of the Grave; and as the principle Design of Tragedy is to raise Commiseration and Terror in the Minds of the Audience, we shall defeat this great End, if we always make Virtue and Innocence happy and successful.”
—Joseph Addison (1672–1719)
