A
Over the last century, engineers all over the world have spared no effort to achieve the unachievable in bridge design.
Danyang-Kunshan Grand Bridge
No bridge is as long as the Danyang-Kunshan Grand Bridge in the world. The 164.8-kilometre-long bridge built in 2011 in China operates as part of the Beijing-Shanghai High-Speed Railway. The trip from Ningbo to Jiaxing that previously took 4.5 hours has been reduced to two, thanks to this bridge.
Rio-Niterói Bridge
Completed in 1974, the Rio-Niterói Bridge in Brazil is the second-longest bridge in all of Latin America connecting the cities of Rio and Niterói across the Guanabara Bay. The Rio-Niterói Bridge is technically known as a “box-girder (箱形梁)” bridge, made of special concrete. It receives an astonishing 140,000 (or more) vehicles per day.
Hartland Covered Bridge
The Hartland Covered Bridge is the world’s longest covered bridge. The 1,282-foot-long bridge was opened in 1901 and has been on Canada’s list of National Historic Sites since 1980. Although it was originally built without a roof, the bridge was capped with wooden materials during the repairs in 1921.
Jiaozhou Bay Bridge
The newly-built Jiaozhou Bay Bridge in China was named “world’s longest bridge over water” by Guinness Book of World Records in 2011, a title previously held by the Lake Pontchartrain Causeway. The dispute was settled when the title of “longest continuous bridge over water” was given to the causeway, with the Jiaozhou Bay Bridge receiving the title of “longest bridge over water”.
