A new wave of mega-sized container ships are now under construction and changing the shipping industry. These new ships are so massive they will require retrofitting of the world's cargo ports and canals.
Engineers face the extreme challenge of carving a 45-mile tunnel in Iceland, at a remote and dangerous site. The tunnel is part of a massive project to construct one of the world's largest dams, and the construction comes with enormous costs.
The longest, cable-stayed bridge in the US is constructed at one of the most difficult sites imaginable, in Charleston, South Carolina. Hurricanes, earthquakes and the world's biggest container ships are a constant threat to the construction and crews building this massive structure.
French engineers are erecting the tallest bridge in the world, the Millau Viaduct. When complete, the massive cable-stayed bridge will solve enormous traffic issues in France and will be Europe's largest engineering project.
Open-pit mine crews work around the clock digging up iron ore to meet the global demand for steel production, but outdated machines slow their efforts. To meet their demands, engineers have developed the fastest, most technologically advanced excavator ever built.
The Oakland Bay Bridge is an earthquake-proof span that's the largest construction project in California history. When complete, the bridge will link San Francisco to Oakland and the East Bay, replacing the most heavily trafficked bridge in the country.
