Engineers never cease to amaze, they are always creating one amazing technology after another. One of the most unbelievable work of engineers all over the world is the creation of bridges over large water bodies such as lakes, seas, and oceans. Few people can comprehend how that gets to be a possibility. Considering how deep these waterbodies are and how wide they stretched, its difficult to imagine how engineers lay structures in the water until they finally come up with a bridge across the sea. Anyway, the engineers understand their work and for this reason, they are able to put up structures even in water. Here are four amazing sea bridges across the world
1. Golden Gate Bridge, San Francisco
Golden Gate Bridge in San Francisco, USA has been named one of the Wonders of the Modern world by the American .Society of Civil Engineers. This is owing to its magical beauty, excellent construction, and incredible design. The bridge is also one of the features that attract tourists to San Francisco area.
Constructed in 1937, the bridge was held as the longest bridge in the world until this changed in 1964. It is very long, it spans one-mile-wide and the three-mile-long channel between San Francisco Bay and the Pacific Ocean. The Golden Gate Bridge is also the most photographed bridge in the world given the high number of tourists it attracts and its significant status as a Wonder of the Modern World.
Before the construction of the Golden Gate Bridge, many people were skeptical about the possibility of such a bridge coming to be. Its construction in 1937 however allayed their doubts.
2. Jiaozhou Bay Bridge, China
This recently constructed bridge in China is currently the longest sea bridge in the world. It is 16.6 miles (26.4 km) long. It connects Qingdao, a port city in eastern China with the offshore island of Huangdao.
Jiaozhou Bay Bridge is a cross between three different bridge types namely suspension bridge, self anchored bridge, and cable-stayed bridge. The bridge has been designed to be able to withstand earthquakes, typhoons, and hurricanes. It is constructed in a T shape.
3. Akashi Kaikyo Bridge, Japan
Akashi Kaikyo Bridge in Japan is the world’s longest suspension bridge. It is 2.4 miles (3.9 km) in length and connects the Pacific Ocean to the Sea of Japan. It runs from the city of Kobe in mainland Honshu up to the island of Awaji in Hyogo Pref.
The construction of Akashi Kaikyo Bridge was done by two million workers and took 10 years to be complete. 181,000 tonnes of steel and 1.4 million cubic meters of concrete were incorporated into the construction of the amazing bridge. It is said that the length of steel cable used in the construction of the bridge could be wound around the earth seven times.
The Japanese bridge has six lanes on which are used by motorists, cyclists, and others. Its construction was prompted by a 1955 ferry disaster in the Akashi Straits.
4. Confederation Bridge, Canada
Confederation Bridge in Canada is one of the few bridges in the world that pass above iced sea waters. The bridge spans Abegweit Passage of Northumberland Strait. It connects Prince Edward Island with the mainland of New Brunswick. It is 8 miles (12.9 km) in terms of length. It is a two-lane bridge which was constructed between 1993 and 1997.
