Kansai International Airport
Japan's Kansai Airport is one of the greatest engineering achievements in the world, but it was built on a man-made island the size of Monaco and now the island is sinking.

Autobahn
The Autobahn is nearly 7,300 miles (11,750 km) long, enough to cross the United States twice. But it's all packed into an area roughly the size of Montana! Discover what it takes to build, operate, and drive the world's greatest super highway.

Itaipú Dam
Itaipu Dam, the world's largest hydroelectric power plant, is a triumph of giant-scale engineering. Learn how forty thousand construction workers diverted the world's 7th largest river.

Akashi Kaikyo Bridge
The Akashi Kaikyo Bridge is the world's longest single-span suspension bridge. But during construction in 1995, it was rocked by an earthquake in Kobe, Japan. The bridge withstood the quake, but the question remains—could it one day collapse?

Petronas Towers
The 450-meter Petronas Towers, the tallest twin towers on the planet, pushed the outer limits of construction technology and stand as a symbol of Malaysian pride and modernity. But building the towers was a construction challenge like no other and the six-year endeavor turned out to be a high-risk project with a hugely ambitious schedule.

Golden Gate Bridge
In the face of powerful natural forces - constant erosion, violent storms, hurricanes, powerful underwater currents and earthquakes - the Golden Gate Bridge was once thought impossible to build. But engineers, designers and construction teams conquered wind speeds of up to 100 miles per hour, and built the Bridge to withstand a potential sway of up to 27 feet. Megastructures: Golden Gate Bridge will reveal at a nuts & bolts level how this awesome structure was originally designed and built and how it will survive into the future.

North Sea Wall
The construction of this colossal hydraulic-powered moveable barrier is one of the greatest feats of civil engineering in history. Three sandbars were built up into islands to accommodate harbours, material yards and work sites. A dam connected two of the islands, effectively creating three channels in the estuaries; each protected by a section of the barrier. Described by the American Society of Civil Engineers as "One of the Seven Wonders of the Modern World", the North Sea Wall has conquered the elements and defied the oceans.

World's Busiest Port
Straddling one of the world's busiest shipping lanes, this is the port of call for a quarter of the world's containers and half the world's supply of oil. Now, imagine if something at this port were to go horribly wrong...

Tau Tona City Of Gold
Tau Tona is an astounding feat of engineering- the deepest, largest gold mine on earth. Thirty five thousand people work in the mine three miles below the surface of the earth. It is an entirely artificial environment with its own weather system. The engineering equipment and massive mining vehicles are some of the largest and most unusual used anywhere on the planet.

Oasis
The world's tallest hotel, the highest water slide outside North America, and a Venice carved from the shores of the Persian Gulf--all are part of tiny Dubai's farsighted attempt to prepare for the day the oil runs out. This cash-rich sheikdom, one of the seven United Arab Emirates, was once known for the largest artificial harbor in the world. Today its leaders are engineering, in every sense of the word, a vacation Mecca for businessmen and tourists. Already, the Burj-Al-Arab hotel on its own man-made island with its striking sail façade and two-story suites is considered the world's only seven-star hotel. Next door the Wild Wadi Water Park is a quintessential oasis in the desert, thanks to desalination. And everywhere, modernity is fast encroaching on a society where men still wear the traditional dishdashah and prayers to Allah air throughout the streets.
