three hours to just half an hour.
1. Brief Introduction
Hong Kong–Zhuhai–Macau Bridge: the world`s longest sea-crossing bridge, one of the most challenging constructions of its kind un.dertaken in the world to date.
.
2.Features and Difficulties
Hong Kong-Zhuhai-Macao Bridge is the national key project featured with strategic significance, large involvement, highly difficult level of construction, long construction time, high requirement on technical design and environmental protection, many participant parties, complex management and coordination.

4. The Immersed Tube Tunnel
.
4. The Immersed Tube Tunnel
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 immersed tube tunnel （沉管隧道）in open waters.
.
3. Two Artificial Islands
the West Artificial Island
the East Artificial Island
.
3. Two Artificial Islands
•The East Island has 59 round steel cylinders圆钢筒. •The West Island has 61 round steel cylinders. •The diameter of a single cylinder is 22.0m, and the cylinder wall is 16mm thick. •The height of round steel cylinder is 40.5m to 50.5m. •The round steel cylinder weighs 445t to 507t.
1.the life span of the bridge is set at 120 years.
2.It reportedly can stand magnitude-8 earthquake, scale-16 typhoon as well as the collision with a 300,000-ton ship

2.Features and Difficulties
this project features a design-andbuild contract, coordination of the three regional governments in the construction and management, and close attention from the society. Moreover, there are 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 route crosses the busiest shipping area of the Lingding Sea.
