PM Modi To Unveil India’s Longest Sea Bridge 'Atal Setu' On Jan 12 Place in News 6 min read

India's longest sea bridge, the Atal Setu or Mumbai Trans Harbour Link (MTHL), is all set to be inaugurated by Prime Minister Narendra Modi on Friday, January 12th. 

  • The bridge is designed to accommodate around 70,000 vehicles daily, connecting Sewri in Mumbai to Chirle in Navi Mumbai.

Some facts about Atal Setu:

  • The Mumbai Trans Harbour Link is a bridge that spans 21.8 km in length and will connect the cities of Mumbai and Navi Mumbai. Once inaugurated, it will become the longest sea bridge in the country and the 12th longest in the world.
  • The bridge comprises a 16.5-kilometre sea link and a 5.5-kilometre land link. The sea link is a six-lane highway with three lanes on either side.
  • The proposal to construct the Mumbai Trans Harbour Link (MTHL) was first introduced in the early 1960s, with plans to build it between Mumbai and Uran in Navi Mumbai. Unfortunately, the construction plans were never fulfilled due to a series of setbacks. However, in 2017, the Maharashtra government assigned the Mumbai Metropolitan Region Development Authority (MMRDA) to build the bridge.
  • The project received an Official Development Assistance (ODA )loan of approximately Rs 18,750 crore from the Japan International Cooperation Agency, which helped to move it forward. The estimated cost of constructing the bridge, according to the MMRDA, is around Rs 17,843 crore. 
  • The sea bridge will allow motorists to travel at a maximum speed of 100 kmph, but heavy vehicles, motorcycles, autorickshaws and tractors will not be allowed to use it.
  • The bridge has lighting poles designed to withstand high-velocity winds during monsoons. 
  • It is also equipped with a lightning protection system to safeguard against potential damage caused by lightning.
  • An 8.5-km noise barrier has been installed from Sewri, as this portion of the bridge passes through a flamingo-protected area and Bhabha Atomic Research Centre.
  • Built 15 metres above sea level, the bridge required digging 47 metres into the sea bed.
