The strength and support to the bridge towers was provided by 3' diameter cable weighing up to 15000 tons
Join the small islands into one big island with
Missions
Remove 200 million tons of rocks by giant earth movers
Under water dredgers arrived at the site and soft mud up to 40 ft was removed from the sea
The biggest land moving exercises ever i.e. 600 million tons of material was removed
Enough to fill ancient Roman Coliseum 200 times
