How is the bridge supported?
Verrazano, an Italian about whom little is known, sailed into New York Harbour in 1524
and named it Angouleme. He described it as 'a very agreeable situation located within
two small hills in the midst of which flowed a great river.' Though Verrazano is by no
means considered to be a great explorer, his name will probably remain immortal, for on
November 21st, 1964, the longest suspension bridge in the world was named after him.
The Verrazano Bridge, which was designed by Othmar Ammann, joins Brooklyn to Staten Island.
It has a span of 4,260 feet. The bridge is so long that the shape of the earth had to be
taken into account by its designer. Two great towers support four huge cables. The towers
are built on immense underwater platforms make of steel and concrete.
The platforms extend to a depth of over 100 feet under the sea. These alone took sixteen
months to build. Above the surface of the water, the towers rise to a height of nearly 700
feet. They support the cables from which the bridge has been suspended.
Each of the four cables contains 26,108 lengths of wire. It has been estimated that if
the bridge were packed with cars, it would still only be carrying a third of its total
capacity. However, size and strength are not the only important things about this bridge.
Despite its immensity, it is both simple and elegant, fulfilling its designer's dream to
create 'an enormous object drawn as faintly as possible'.
