The Amazing Sutong Bridge in China

(A cable-stayed bridge with the world’s longest main span (1,088 m); its overall length is 8,206 m and the two bridge towers are the world’s second tallest at 306 m Moving further east, here’s the Sutong Bridge that spans the Yangtze River and connects Sutong (Suzhou) and Nantong in China. It shortens the commute from Shanghai to Nantong, making ferry service superfluous and heightening Nantong’s importance as part of the Yangtze River Delta economic zone. The opening of the bridge in May 2008 has brought foreign investments to the city and spurned the development of poorer northern Jiangsu regions. No wonder, with a status project that cost €1.3 billion.)

The Amazing Akashi Bridge in Japan

(the world’s longest suspension bridge with a total length of 3,911 m and contains a 6-lane highway Moving yet further east, we reach the Akashi Bridge (also Akashi-Kaikyo or Pearl Bridge) in Kobe, Japan. With a centre span of 1,991 m, it is the world’s longest suspension bridge and links Kobe with the mainland of Honshu. Since the bridge’s opening in 1998, crossing the Akashi Strait has become much safer as the bridge has been built to withstand strong winds, sea currents and earthquakes. Before then, passengers used to rely on ferries that were prone to accidents due to severe storms in the region.)

The Amazing Jadukata Bridge, the longest span cantilever bridge in India

(central span of 140 m, stretches so naturally from one shore to the other that it seems to grow out of the rich vegetation itself Leaving Europe to move further east, we come to the Indian Jadukata Bridge in Ranikor in the West Khasi Hills District of Meghalaya, 130 km from its capital, Shillong. This bridge over the Jadukata river is close to the Indo-Bangladesh border and therefore a vital link on an important road in this border state. Even cost wise, compared to the other bridges featured here, it is a lightweight at €1.5 million)

The Amazing Erasmus Bridge in Rotterdam

(808 m long, cost €75 million to construct and was opened in September 1996)
The Erasmus Bridge in Rotterdam does not need to hide behind the Oresundbridge as it can boast a record of its own: its southern part is the largest and heaviest bascule bridge in Western Europe and has the largest panel of its type in the world, allowing tall ships to pass. The bridge is nicknamed “The Swan” because of its 139 m high asymmetrical pylon that overlooks the city like the graceful neck of a swan.

The Amazing Millau Viaduct in France

(2,460 m long, 32 m wide and 343 m high at the highest point)

The Millau Viaduct in France is the world’s tallest vehicular bridge. In 2004, after 17 years of planning and work, it was finally completed and formed the missing link in the A75, connecting Paris and Perpignan. Cost: Euro 400 million, but that should be recovered fast at a cost of €3.09 for bicycles, €5.50 for cars and €27.50 for trucks (off season). However, according to the web site, the route saves more than one hour when travelling from Paris and almost €50 in tolls. The state-of-the art construction required 85,000 m3 of concrete and used the latest techniques like laser, GPS, sliders, self-climbing formwork, specific surface coats and high performance concrete.

The Amazing Magdeburg Water Bridge :Germany

(918 m long, 34 m wide and 4.25 m)
At first glance, the Water Bridge in Magdeburg, Germany, seems nothing special; just another canal bridge. But look again and it’s a water bridge across water, forming a water intersection that is the biggest water crossing in Europe! The world’s largest water bridge, with a span of 106 m between its pillars, opened in October 2003, on the back of five years of construction, 24,000 tons of steel, and 68,000 m³ of reinforced concrete. Regaining the construction cost of €500 million probably won’t take long as the bridge shortens travel times for ships considerably and eases traffic on other routes. Before the opening of the water bridge, ships moving between the Midland Canal and the Elbe-Havel Canal had to make a 12-km detour through the Rothensee lock, along the River Elbe and back up Niegripp lock. Now the bridge connects Hannover and Berlin directly and also Berlin’s inland harbour network with the ports along the Rhine. A double lock was constructed to descend to the Elbe-Havel Canal and a single Rothensee lock was constructed at the other end of the water bridge to descend to the Elbe and the Magdeburg harbour, making it independent of water levels and therefore navigable even for large ships.....
