港珠澳大橋
Completed in 2018, the Hong Kong–Zhuhai–Macau Bridge connects Hong Kong, Zhuhai and Macau through "a series of bridges, sub-sea tunnels, viaducts and artificial islands". It is "the world's longest sea-crossing bridge" at 55 kilometres. The bridge was built with the intention of meeting increasing demands for passengers travelling between Hong Kong, Mainland China and Macau via the establishment of a new transportation link between the East and West banks of the Pearl River Delta.
