The End! Thanks for your attention!
3. 工程总体方案
The first major combined bridge and tunnel sea-crossing project in China. Cost approximately RMB 105 billion. Construction began in 15 December 2009 at Zhuhai. Will reduce travel time from Hong Kong to Macau or Zhuhai from over three hours to just half an hour.
2.Features and Difficulties
this project features a design-and-
build contract, coordination of the three
regional governments in the construction and management, and close attention from the society. Moreover, there are

British newspaper “The Guardian”
named the megastructure one of its “ seven wonders of the modern world
near completion.”
It will be the first new land transport link between the east and west coasts of the Pearl River, The bridge will benefit the economic development of the whole of the Delta. The bridge will create a regional transport network, improving
environmental constraints as the alignment runs across the national conservation area for the Chinese white dolphins, as well as
complicated navigation traffic conditions as

The water resistance ratio must be limited to 10% to prevent accumulation of sediment at the Lingdingyang Channel, otherwise it will impose serious impact on the Pearl River flow path and flood-discharge capacity, according to a government report. Due to the long distances between the cities, the project is actually a series of bridges and tunnels, connected by artificial islands ， this was the first time China has built an
the route crosses the busiest shipping area of the Lingding Sea.
