Hong Kong-Zhuhai-Macao bridge

The Hong Kong-Zhuhai-Macao bridge, the world's longest manmade sea crossing, completed major work of construction on Dec. 31, 2017 as scheduled.

It took six years preparation, and eight years to build the 55-kilometer-long bridge linking Hong Kong, Zhuhai and Macao.

Major work on the bridge consisted of a 22.9-kilometer-long main bridge, a 6.7-kilometer-long tunnel and an artificial island off the bridge, which is considered the most technically demanding part of the whole construction.

The Y-shaped bridge will cut travel time between Hong Kong and Zhuhai from three hours to just 30 minutes. With expanding capacities of roads, railways and ports, the Greater Bay Area will see a highly convenient and efficient transportation network.
