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 (16131680)
“If I knew for a certainty that a man was coming to my house with the conscious design of doing me good, I should run for my life ... for fear that I should get some of his good done to me,some of its virus mingled with my blood.”
—Henry David Thoreau (18171862)
“A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.”
—Freeman Dyson (b. 1923)
