VOICE TWO:

And I'm Steve Ember with Explorations in VOA Special English. There are many natural wonders in the United States. Today, we take you to seven man-made wonders in America.

(MUSIC)

VOICE ONE:

Against the city's gleaming spires²,

Above the ships that ply³ the stream,

A bridge of haunting beauty stands 鈥揊ulfillment of an artist's dream.


The Brooklyn Bridge

That poem is about our first man-made wonder 鈥?the Brooklyn Bridge in New York City. It extends more than four hundred eighty meters over the East River to connect the areas of Brooklyn and Manhattan. A famous bridge builder David B. Steinman wrote the poem. But he did not build the Brooklyn Bridge.

VOICE TWO:

It was the dream of another man, John A. Roebling. He was a member of the design team and became chief engineer of the building project in eighteen sixty-seven. Sadly, he became sick and died before work even started. He had an accident when visiting the area where the bridge was to be built.

Building began in eighteen seventy. It was very dangerous. Few records were kept on such events. But, historians say between twenty and thirty men died as a result of the building project. Some died from falling off the bridge or from being struck by equipment.

Others died or were injured from working in the structures called caissons. These lay deep below the surface of the Earth. The workers would get a pressure sickness called the bends.

VOICE ONE:

John Roebling's son, Washington, was severely⁴ disabled by the bends. He had been named chief engineer of the Brooklyn Bridge project soon after his father died. Washington Roebling continued the work from his home after he was disabled.

The Brooklyn Bridge opened on May twenty-fourth, eighteen eighty-three. At the time, it was the longest suspension bridge in the world. It is still a beautiful structure. The bridge has tens of thousands of suspension wires that spread many meters across and up and down to towers on each side. From a distance the many wires look like the stringed musical instrument called the harp⁵. The center of the Brooklyn Bridge rises almost forty meters above the East River. It is one of the most famous and beloved New York City landmarks⁷.

(MUSIC)

VOICE TWO:

Another bridge makes our list of the seven man-made wonders. This one is in
The Golden Gate Bridge and San Fransico

northern California. The Golden Gate Bridge is named after the waterway it crosses. The Golden Gate Strait lies between the Pacific Ocean and the San Francisco Bay. The bridge over it links the city of San Francisco with Marin County.

Joseph Strauss was the chief engineer of the Golden Gate Bridge. Building began in nineteen thirty-three. The bridge opened in nineteen thirty-seven. It is almost one thousand three hundred meters long. It was the longest suspension bridge in the world for almost thirty years. Then, in nineteen sixty-four, the larger Verrazano Narrows bridge opened in New York City.

VOICE ONE:

Joseph Strauss used newly developed protective equipment for the men who worked on the bridge. These included a special safety net under the bridge. But still, eleven men were killed during construction.

The color of the bridge, International Orange, is very important. It was chosen partly because it is easier to see through the heavy fog that often covers San Francisco. Many people consider the Golden Gate Bridge the most beautiful bridge structure in the world.

VOICE TWO:

Joseph Strauss wrote a poem about his bridge when the work was done. Here is part of The Mighty⁸ Task is Done.

At last the mighty task is done;

Resplendent in the western sun

The Bridge looms⁹ mountain high;

Its titan piers¹⁰ grip ocean floor,

Its great steel arms link shore with shore,

Its towers pierce the sky.

(MUSIC)

VOICE TWO:


The Gateway¹¹ Arch

Our next man-made wonder is as famous a landmark⁶ in the Midwest United States as the first two are on the East and West Coasts. The Gateway Arch in Saint Louis, Missouri is the tallest freestanding monument in the nation. The shiny, steel curve rises to almost two hundred meters. Below, the arch is exactly as wide as it is tall.

The famous Finnish American building designer, Eero Saarinen, designed the Gateway Arch during a national competition in the late nineteen forties. However, building did not begin until February, nineteen sixty-three. It was completed in October, nineteen sixty-five. Later a transport system was added to permit people to visit an observation area inside the top of the arch.

The Gateway Arch rises above the Mississippi River. It was named in honor of Saint Louis, which was historically called The Gateway to the West.

(MUSIC)

VOICE ONE:

There is one place in America that almost everyone agrees is a man-made wonder:
Mount Rushmore

South Dakota's Mount Rushmore. Giant faces of four great American presidents are cut into the rock near the top of Mount Rushmore in the Black Hills. Each face is about eighteen meters high.

Sculptor¹² Gutzon Borglum was chosen to create the Mount Rushmore memorial. It was completed in nineteen forty-one, after fourteen years.

Each president represents important values in America. George Washington led the cause for independence. Thomas Jefferson represented the belief in equality. Abraham Lincoln ended slavery and saved the Union. And Theodore Roosevelt was a conservationist and symbol of the progressive spirit of America.

(MUSIC)

VOICE TWO:


Hoover Dam

We go next to one of the largest and most difficult structures ever built in the United States: Hoover Dam. The dam is in the Black Canyon¹³, near Las Vegas, Nevada. It controls the water of the Colorado River and produces electric power.

Workers began to build Hoover Dam in nineteen thirty-one. They finished in just five years. More than twenty thousand men worked on the project. It was very dangerous. Ninety-six workers were killed. Many others were injured.

The Hoover Dam is two hundred twenty-one meters tall. It weighs more than six and one half million tons. At the time, it was the largest and tallest dam in the world. And it was one of the largest producers of electric power ever built. Hoover Dam also created Lake Mead¹⁴, the largest man-made lake in America.

(MUSIC)

VOICE ONE:

Another man-made wonder of the United States was built long before the nation was
Cliff dwellings¹⁵ at Mesa Verde

established. About nine hundred years ago, the Ancestral Puebloan people built villages high in the walls of canyons¹⁶ in Mesa Verde, Colorado. Six hundred cliff dwellings are now part of the Mesa Verde National Park.

Visitors can stand at the top of the mesas and look into the dwellings almost hidden in openings of the rock walls. The Puebloan people cut small steps into the rock. A series of such steps connected buildings containing hundreds of rooms.

The rock walls have protected the buildings from severe weather in the area. So they remain mostly unchanged in the hundreds of years since they were built.

(MUSIC)

VOICE TWO:


The Space Needle

Our final man-made wonder is in the northwestern city of Seattle, Washington. The Space Needle was built as the central structure for the nineteen sixty-two World's Fair.

Edward Carlson designed the one hundred eighty-four meter tall structure. The Space Needle has a wide base on the ground. It is narrow in the middle. On top is a large ring-like structure.

The structure was meant to look like a flying saucer, a vehicle that was popular in science fiction space travel stories. The saucer includes an observation area and eating-place. The restaurant slowly turns to provide visitors with a three hundred sixty degree view of Seattle.

The Space Needle was not very costly¹⁷. The building project cost about four million five hundred thousand dollars. It was designed and completed in about a year and opened on the first day of the World's Fair. Today, the Space Needle is the most popular place for visitors to Seattle. And it remains¹⁸ the internationally known symbol of the city.
