Tsing Ma Bridge is a bridge in Hong Kong. It is the world's 16th-longest span suspension bridge, and was the second longest at the time of its completion. The bridge was named after the two islands it connects, namely Tsing Yi and Ma Wan. It has two decks and carries both road and rail traffic, which also makes it the largest suspension bridge of this type. The bridge has a main span of 1,377 metres (4,518 ft) and a height of 206 metres (676 ft). The span is the longest of all bridges in the world carrying rail traffic.

Tsing Yi, sometimes referred to as Tsing Yi Island, is an island in the urban area of Hong Kong, to the northwest of Hong Kong Island and south of Tsuen Wan. With an area of 10.69 km2 (4.13 sq mi), the island has been extended drastically by reclamation along almost all its natural shore and the annexation of Nga Ying Chau (牙鷹洲) and Chau Tsai. Three major bays or harbours, Tsing Yi Lagoon, Mun Tsai Tong and Tsing Yi Bay (青衣灣) in the northeast, have been completely reclaimed for new towns.
