Atal Setu: Prime Minister Narendra Modi recently inaugurated the Mumbai Trans Harbour Link (MTHL), a six-lane sea bridge reputed to be among the longest. The 21.8 km long bridge, which was built with expenditures of Rs 18,000 crores and dedicated to the memory of the late former prime minister Atal Bihari Vajpayee, is a notable piece of national infrastructure. Technologies that improve the bridge’s efficiency and environmental friendliness were used in the construction of the new Atal Setu Bridge. The technology is being employed for the first time in construction by Indian experts, according to MMRDA metropolitan commissioner Sanjay Mukherjee. In this article, we will share the top 5 technologies used in the bridge.
5 amazing technologies used to construct the Atal Setu
Steel Deck
Long spans and structural stability are guaranteed by the network of steel beams supported by the corrugated steel plate that makes up the bridge deck. The lightweight steel deck is said to reduce the bridge’s overall weight and improve its resistance to weight-lifting in comparison to traditional concrete decking.
Reverse circulation rigs
It has unique rigs that help reduce noise and vibrations, protecting the nearby marine life.
Real-time traffic info
While driving on the Atal Bridge, drivers will notice screens that provide them with up-to-date information on traffic patterns and incidents that have happened on the bridge and other roads.
Earthquake-resistance
Base isolation bearings, which are primarily intended to absorb seismic forces, have been employed as shock absorbers on the bridge. This will eliminate the possibility of a collapse and allow for controlled movement during an earthquake. The inventive construction has been designed to endure seismic activity measuring up to 6.5 on the Richter scale.
Eco-friendly lighting
The energy-efficient LED lights used in the bridge’s lighting system are made with special consideration to cause the least amount of disturbance to the aquatic ecosystem.
