Danyang Kunshan Bridge - longest bridge in the world
Opened on 30 June 2011, the Danyang–Kunshan Grand Bridge is the longest bridge in the world and is part of the rail line connecting Nanjing, capital city of Jiangsu Province, with Shanghai. The 164.8-kilometer long viaduct took four years to build (2006-2010) and cost about US$8.5 billion.
Built by the China Road and Bridge Corporation (CRBC), a subsidiary of China Communications Construction Company, the Danyang-Kunshan Grand Bridge was built with a workforce of 10,000 people, using close to 450,000 tons of steel. The bridge begins from Danyang and continues through Changzhou, Wuxi, Suzhou before ending in Kunshan, with a 9-km open-water section spanning across Yangcheng Lake (阳澄湖) in Suzhou.

Built at a cost of US$3.5 billion, the Crimean Bridge crosses the Strait of Kerch between the Taman Peninsula of Krasnodar Krai and the Kerch Peninsular of Crimea and is designed to carry up to 40,000 vehicles and 47 pairs of trains daily.

Hong Kong-Zhuhai-Macau Bridge - the US$18.8-billion bridge
Opened on 24 October 2018, the Hong Kong–Zhuhai–Macau Bridge (HZM bridge) is the most expensive bridge constructed to date at a cost of 127 billion yuan or US$18.8 billion dollars. As its name suggests, the HZM bridge connects Hong Kong, Macau and Zhuhai - three major cities on the Pearl River Delta.
The Hong Kong-Zhuhai-Macau bridge stretches 55 kilometers long, composed of three cable-stayed bridges, an undersea tunnel and four artificial islands. The purpose of the 6.7-km undesea tunnel which runs between two artificial islands is to enable shipping to pass through. With the HZM bridge, what was once a 4-hour travel between Zhuhai and Hong Kong has been reduced to a mere 30-minute drive.
