bridges, like the George Washington Bridge, and some of the tunnels, such as
the Lincoln and Holland Tunnels, are famous.But the
most famous of all is the Brooklyn Bridge, which was built over 100 years ago.
Today, engineers have the experience and the special machines to do such
things, but at that time, no one knew how to do them.The Brooklyn Bridge was the first
bridge of its kind in the world.The box which
Washington had studied in Europe was used.It was the
size of a house and it was made of wood.It had three
sides and a top, but no bottom.Air was forced into the
box and water was forced out so the workers could work underwater.No one understood the problems of this kind of work.It was very dangerous and many men were sick.Needless to say (不用说), they were also
frightened.Accidents were frequent.Roebling spent a great deal of time with the workers in the box to
encourage them.
The box began to affect the men.Some of them felt strange pains in different parts of their bodies.One day, a worker began to have strong pains in his stomach.He had been well and had begun work only half an hour before, but
within minutes he was dead.This sudden incident was
repeated several more times with other men.Roebling
himself had a similar attack.He couldn’t talk or hear.Within days he became
paralyzed(瘫痪的) and people feared that he, too, might
die.But he recovered after a week or two and went back
to work.A little while later, Roebling had a second
attack, more serious than the first.This time he was
crippled.He was unable to work again for the rest of his
life.
The bridge was a great success.People came from everywhere to see this strong and beautiful
structure.It was one of the wonders of the nineteenth
century, and it is still a wonder today.There is more
traffic on it than ever before, yet the bridge remains sturdy.
