The Danyang-Kunshan Grand Bridge, located in China’s Jiangsu province, is a marvel of modern engineering and a testament to human ingenuity. As the world’s longest viaduct, spanning an impressive 164.8 kilometers (102.4 miles), this bridge is not only an engineering feat but also a vital transportation artery connecting the cities of Shanghai and Beijing. In this article, we will delve into the history, construction, and significance of the Danyang-Kunshan Grand Bridge, exploring its impact on the region and the world of civil engineering.
Construction and Design
The Danyang-Kunshan Grand Bridge was constructed between 2006 and 2010, with a total investment of approximately 8.5 billion yuan (around $1.2 billion USD). The bridge’s design is a combination of simply supported and continuous beams, with a maximum span of 100 meters (328 feet). The bridge’s deck is supported by 9,341 piers, each with a foundation depth of up to 80 meters (262 feet). The bridge’s design and construction were undertaken by the China Railway Group and the China Road and Bridge Corporation, with the assistance of international engineering consultants.
