Design
Ammann, the master bridge builder and chief architect of the Port Authority, chose the steel arch design after rejecting a cantilever and suspension design as expensive and impractical for the site, given a requirement by the Port Authority that the bridge must be able to accommodate the future addition of rapid transit tracks.
The eventual design of the bridge called for a graceful arch that soars 266 feet (69 m) above the Kill Van Kull and supports a road bed for 1,675 feet (511 m) without intermediary piers. The total length of the bridge is 8,640 feet (2,633 m) with a mid-span clearance above the water of 150 feet (46 m). The arch resembles a parabola, but is made up of 40 linear segments.
The design of the steel arch is based on the Hell Gate Bridge designed by Ammann's mentor, Gustav Lindenthal. Gilbert had designed an ornamental granite sheathing over the steelwork as part of the original proposal, but as in the case of the George Washington Bridge, the stone sheathing was eliminated in order to lower the cost of the bridge, leaving the steel trusses exposed. It was the first bridge to employ the use of manganese steel for the main arch ribs and rivets.

Famous quotes containing the word design:
“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)
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
“Westerners inherit
A design for living
Deeper into matter—
Not without due patter
Of a great misgiving.”
—Robert Frost (1874–1963)
