Engineering Wonders of the Modern World

Zhangjiajie, China: The Bailong Elevator is the world’s largest exteriorelevator. At over 1,000 feet tall, this elevator looms high midway up a cliff overlooking a valley far below. Moreover, the elevator is mostly glass, affording passengers a dizzying view to the depths below. There is some concern, however, about the elevator’s long-term impact on the surrounding natural environment.Worlds Tallest Bridge France

Millau, France: The Millau Viaduct is the highest bridge in the world. At almost 1,000 feet high (taller than the even the Eiffel Tower) and over 8,000 feet long it sometimes sits above the cloud line, as shown in the beautiful photographs above. The engineered wonder of the bridge itself is nearly as amazing as the view of the valley below.Worlds Largest Underground Pipeline

Panama Canal


The dream of Spanish conquistadors and the failed ambition of famed French canal builder Ferdinand de Lesseps, the Panama Canal is one of civil engineering's greatest triumphs. Under the direction of U.S. Col. George Washington Goethals, 42,000 workers dredged, blasted and excavated the path stretching from Colon to Balboa. They moved enough earth and rubble to bury the island of Manhattan to a depth of 12-feet, or enough to open a 16-foot-wide tunnel to the center of the Earth.

The canal was finished on time and within budget. Despite this, after completion a challenge remained: How to tame the flood waters of the Chagres River, known to rise 25-feet in a single day during monsoon season? The engineers' solution was to erect a dam that, at the time, formed the world's largest man-made lake. The Canal operates as regularly today as it did in 1914.


 In each transit, 52 million gallons of fresh water is lost, but quickly replaced by Panama's heavy rainfall. The canal remains a testament to the combined skills of structural, geotechnical, hydraulic and sanitary engineers.
