We've come a long way in bridge building since crossing a river on a fallen log. The first bridges were built with wooden planks, ropes and stones. Soon, stronger material were required. Wood and stone bridges gave way to iron, then to steel ones. Bridge building techniques also evolved: beam, cantilevered, cable-stayed, and suspension bridges - each with advantages that made it the right choice for a particular location. Bridges are stylish: from classical to modern, they are as much a work of art as they are marvels of engineering.
Height of 496 m (1,627 ft). This 1,222 m (4,009 ft) long suspension bridge is the world’s highest bridge since 2009. Located in the Hubei Province, it crosses the valley of the Sidu River
September 9, 2008, Banpo Bridge in Seoul (South Korea) had a massive facelift: a 10,000 tubes fountain that ran on both edges. Once installed, the bridge was turned into a big tourist attraction, as the bridge is firing 190 tons of water per minute using the river water below.
This world famous symbol of the West Coast of the United States and the most popular attraction of San Francisco has a main span of 1,280 meters (4,199 ft) which makes it around the 11th longest span in the world. 11th place may not sound much, but taking into consideration that the bridge opened in 1937 makes it quite remarkable as the other top 10 were built during the last 10-20 years. The Golden Gate bridge is located in San Francisco and is perhaps the city’s most famous attraction. With the view of the bay around it, it is truly a sight to see
Built from 1886 till 1894, this symbol of London is a combined bascule and suspension bridge in London, over the River Thames. It is close to the Tower of London, from which it takes its name. Both the bridge and the castle next to it are one of the most visited monuments not only in London or England, but in Europe and even the entire world
Stretching across the Akashi Strait in the Land of the Rising Sun, the Akashi Kaiyko is a bridge of mind-blowing proportions. Its span stretches an astounding 12,828 feet or nearly 2 1/2 miles. Its towers alone soar 92 stories skyward, almost the height of the Eiffel Tower. And its 6 lanes of freeway make way for 9 million cars each year. It was also built under some of the most severe conditions in the world — including typhoons, tsunamis and over 60 inches of rain a year.
As high as 1125 feet above the Tarn Valley in southern France, acrossing the Millau Viaduct is virtually like flying. This work of Foster & Partners was slightly higher than the Eiffel Tower, took three years to build and opened to public in 2004.In addition of providing views of the valley below, It also viewed the clouds when It’s formed under the bridge. Millau is not the route for those who fear of heights! Millau has a total length of 8071 feet with the longest single span of 1122 feet, so this is very beautiful bridge in miniature form or original form. Bridge deck is supported by 7 pillars and weighs 36,000 tons. 7 towers, each 292 feet tall and weighing 700 tons, fitted to the supporting pillars.
Designed by Heatherwick Studio, this award winning Rolling Bridge is located in Paddington Basin, London. Instead of using conventional bridge open mechanism, that consisting of a single rigid element that rises to let boats pass, the Rolling Bridge rolled itself until the two ends meet.When in horizontal position, the bridge is a steel pedestrian bridge and the normal wood that fully open. The bridge is a circle on one side different from the straight position.
Twelve feet long, this bridge was made by the eight sections of iron and wood, and made curved by hydraulic power handrail mounted on each section.
For more than a century, the Brooklyn Bridge has been connecting the people of Manhattan with millions of bustling Brooklynites. When the bridge opened in 1883, it was considered a marvel of modern engineering — and still is to this today. Upon completion, it was the longest suspension bridge in the world. Additionally, the towers were possibly the tallest structures in the city of New York when they were built. But don't let all the engineering talk confuse you with the bridge's real purpose. One walk across the Brooklyn Bridge, and you instantly get in the New York state of mind. This architectural wonder shows off the beauty of the city like no other.
Lake Pontchartrain Causeway consists of two parallel bridges that are the world’s longest bridge in total length. This bridge across Lake Pontchartrain in southern Louisiana.
