Total length: 8,206 m

Tatara Bridge, Hiroshima and Ehime, Japan.
Total length: 1,480 m

Pont de Normandie, Le Havre–Honfleur, France.

  • The total cable length used to connect the towers is equal to the circumference of the earth (40,075 km)
  • The length of the bridge (4 km) is 63 times the height of Qutub Minar in Delhi
  • The slabs on the bridge are screwed in place by special nuts and bolts. Each slab is unique and had to be fixed at a specific point
  • The piling of the bridge is 100 feet under the sea
  • For fixing the slabs, launching Trusses were used
  • If the Trusses had to be dismantled and moved, it would have taken almost 1 year
  • To save time, Asian Hercules, one of the largest floating cranes in the world, was hired to move the Trusses
  • The rental for the imported Trusses was Rs 1 crore per day
