Bridges are the structures that connect one point to another. The engineers have shown a lot of creativity with the bridges. Bridges are engineering achievements that symbolize determination and the never-ending goal of overcoming nature’s obstacles. Civil engineers have gone to great lengths over the last century to achieve these goals in bridge design. Bridges help in transportation and reduce the distance traveled between two different points.
In this blog, we will take you on a journey across continents and explore the world of the Top 10 Longest Bridges in the World.
Top 10 Longest Bridges in the World
Bridges are not just a physical structure. They are examples of complex engineering and determination. They are used to mend the gap and connect two points. In this blog post, we will learn about these top 10 longest bridges that are examples of sheer strength and determination.
Danyang Kunshan Grand Bridge, China
The Danyang Kushan Grand Bridge in China is the longest bridge in the world. The bridge is 102.4 miles long and was opened in 2011. The bridges are part of the Beijing-Shanghai High-Speed Railway, which connects several major cities in the Yangtze River Delta. A team of 10,000 workers constructed the $8.5 billion structure.
The bridge took four years to construct and can easily defend against an earthquake of magnitude 8.0. The construction took almost 4 years to complete the bridge. The bridge was built by the China Road and Bridge Corporation (CRBC), a subsidiary of China Communications Construction Company.
Length of Bridge: 102.4 miles
Cost: $8.5 million (approximate)
Tianjin Grand Bridge, China
The Tianjin Grand Bridge, which is also in China, is the world’s second-longest bridge. Bridges are critical in China for transporting people from one location to another without experiencing time loss due to obstacles. The bridge is about 97.7 miles long. The bridge was opened in 2011. It took almost four years to construct such a bridge.
The elevated track’s design was chosen to avoid the need for numerous individual structures for crossing roads and railways and to reduce construction time. On top of that, the railway line in this design will require less land area: a railway embankment would require 28.4 hectares per routed kilometre, whereas the bridge will require only 10.9 hectares or less than half the area.
Length of Bridge: 97.7 miles
Cangde Grand Bridge, China
Cangde Grand Bridge is the third longest bridge in the world and is located in China. It is a 72-mile-long bridge and is part of an essential arterial railway that transports people to and from Beijing. The bridge was finished being constructed in 2010. The bridge has a total of 3092 piers. The bridge is designed to withstand earthquakes.
Length of Bridge: 72 miles
Weinan Weihe Grand Bridge, China
The Weinan Weihe Grand Bridge in China is the world’s fourth longest bridge. The bridge is 70.6 miles long. Even though the bridge was completed in 2008, the railway line did not open until February 6, 2010. When it was completed, it was the world’s longest bridge, but two new bridges have since surpassed it.
At least 10,000 people were employed during the construction of the Weinan Weihe Grand Bridge. It travels through the difficult terrain of the Wei River, which is surrounded by vast plains and gently sloping hills. The bridge not only serves as a testament to human capability, but it also allows for faster and more efficient travel, significantly reducing travel time between the two cities.
Length of Bridge: 70.6 miles
Hong Kong-Zhuhai-Macau Bridge, Taiwan
The Hong Kong-Zhuhai-Macau Bridge in Taiwan is the fifth longest bridge in the world. The bridge is 49.5 miles long and was opened in 2018. The bridge consists of a series of smaller bridges. The bridge is widely regarded as a historic wonder. It supports the structure with single-column structures buried deep in the seabed to prevent interference with water currents.
It runs through the Pearl River Estuary, the Lingding Channel, and the Jiuzhou Channel. It is the world’s longest sea crossing and the world’s longest open sea fixed-line.
Length of Bridge: 49.5 miles
Bang Na Expressway, Thailand
The Bang Na Expressway in Thailand is the sixth-longest bridge in the world. The bridge is 33.6 miles long and was opened in 2000. The bridge. There are two toll plazas on the elevated structure, which must be widened to accommodate twelve lanes. Kapsch TrafficCom AB (Sweden) is in charge of the toll system. The Asian Engineering Consultants built and designed the Bang Na Expressway.
Length of Bridge: 33.6 miles
Beijing Grand Bridge, China
The Beijing Grand Bridge in China is the seventh-longest bridge in the world. The bridge is 23.9 miles long and was officially opened in 2011. It connects the Bohali Economic Rim and the Yangtze River Delta on the eastern coast of China. These regions highly require the railways to export their agricultural and natural supplies.
Length of Bridge: 23.9 miles
Lake Pontchartrain Causeway, United States
The Lake Pontchartrain Causeway in Louisiana is the eighth longest bridge in the world. The bridge is about 22.8 miles long and was opened in 1969. The bridge consists of two parallel bridges of the same length. It has a drawbridge at its centre, which raises to let the ships pass. It is also the world’s longest bridge over continuous water.
Length of Bridge: 22.8 miles
Line 1 Wuhan Metro, China
The Line 1 Wuhan Metro in China is the ninth longest bridge in the world. The bridge is about 22.2 miles long and was opened in 2004. The bridge is an elevated metro rail simply named Line 1. It is the world’s longest continuous metro tunnel. It is the first Metro line in China that has been incorrectly identified as a light rail.
Length of Bridge: 22.2 miles
Manchac Swamp Bridge, Louisiana
