The Longest Suspension Bridge in the World
The Longest Suspension Bridge in the World
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, 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'.
