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.
WONDER no. 4: The Langeled Pipeline
More, Norway to Easington, Britain: The Langeled Pipeline is slated to be the longest underwater gas pipeline in the world. It will ultimately supply 20% of Britain’s gas needs, connecting England to the largest gas field in Europe via 750 miles of complex underwater terrain. Engineers have had to account for subzero temperatures an stormy waters in addition to developing techniques for installing the pipeline in the first place. They are able to lay an amazing 8 miles of pipe per day.
