Mumbai Plans 70-Km Underground Tunnel Road Network to Ease Traffic
Imagine Mumbai is super crowded with cars.
To help people move around faster, city planners want to build a giant underground road system, like a secret subway for cars!
This new network will be 70 kilometers long, which is like driving from one end of the city to the other and back.
It will have different parts to connect important places like the airport and business areas.
Building this will help cars go faster, make commutes safer, and connect different parts of the city better.
It's like giving Mumbai a new, hidden layer of roads to make travel easier for everyone.
Mumbai plans a 70-km underground tunnel road network to combat traffic congestion.
The project aims to create a 'third mode of urban mobility' alongside roads and metro.
It will improve connectivity between key areas like BKC and the airport.
The network will be built in three phases, starting with a 16-km link from Worli to the airport.
The estimated cost for this ambitious project is ₹1.05 lakh crore.
