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:
“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)
“For I choose that my remembrances of him should be pleasing, affecting, religious. I will love him as a glorified friend, after the free way of friendship, and not pay him a stiff sign of respect, as men do to those whom they fear. A passage read from his discourses, a moving provocation to works like his, any act or meeting which tends to awaken a pure thought, a flow of love, an original design of virtue, I call a worthy, a true commemoration.”
—Ralph Waldo Emerson (1803–1882)
“What but design of darkness to appall?—
If design govern in a thing so small.”
—Robert Frost (1874–1963)
