Itaipu Dam
River of South America, lies the Itaipْ Dam. Costing 20 billion dollars, the Itaipْ Dam is the world's largest and most powerful hydroelectric power plant. It is a representation of the efforts and accomplishment of two countries, Brazil and Paraguay. The episode examines the efforts undertaken and the sacrifices made to construct the dam, including how the largest diversion channel was constructed to divert water from the world’s 7th largest river away from the main construction site.

Impossible Bridges Greece - Rio-Antirio Bridge
The Rio-Antirio bridge is a cable-stayed bridge near Patra on the Peloponnese, linking the towns of Rio and Antirrio on the western mainland Greece, thus connecting with the rest of Europe.
The bridge dramatically improves access to and from the Peloponnese, which could previously be reached only by ferry or via the isthmus of Corinth at its extreme east end. It has a length of 2252 m (2882 m including the access bridges); as it consists entirely of five cable-stayed spans and four pylons, and it is one of the world's longest cable-stayed suspended decks. Its width is 28 meters -- it has two vehicle lanes per direction, an emergency lane and a pedestrian walkway

Hoover Dam
Throughout human history, mankind has built monuments to its ingenuity and skill. In Egypt it was the Pyramids. Rome, built the Colosseum. The Greeks built the Acropolis. The great cathedrals of Europe raised the skills of their builders to unequalled heights, creating awe inspiring structures. In the Americas, the cliff dwellings of Mesa Verde and the high mountain city of Machu Pichu speak to the skill and ingenuity of their builders. In the modern era, it's buildings that reach near half a mile into the sky, bridges that stretch enormous distances in a single span, and machines that extend mankind's reach far into space. One monument that must surely be counted among the great achievements of mankind is Hoover Dam.

Dubai's Palm Island
An enormous project is underway in the Arabian Gulf that will change the face of the coastline. It is so vast that it can be seen from space. Palm Jumeirah, one of the most audacious engineering projects the world has ever seen, is an artificial island in the shape of a massive palm tree. A breathtaking megastructure and an ambitious engineering feat, Palm Jumeirah is part of an even bigger plan to transform Dubai into one of the world's premiere tourist destinations. But with only a few years to create this paradise island, it's a race against time. Besides the construction of the island, there is also the challenge of building a small city, including 4,500 luxury houses and apartments, 29 hotels, miles of roads, and all the utilities required by the thousands of people who will be living on and using this island including water, electricity, gas and sewage. The project is due for completion in 2008 - are they on course to meet their deadline? And what other megastructures has the Sheikh planned for Dubai
