Come 2023, Mumbai will accommodate India’s first undersea tunnel, which will be part of the the city’s Coastal Road project.
The twin tunnels have a length of 2.07 km of which one kilometre will be under the sea. They are being built as part of the Mumbai Coastal Road Project, a 10.58-km stretch starting from the Marine Drive promenade to the Worli-end of the Bandra-Worli Sea Link.
The road will comprise land-filled roads on areas reclaimed from the sea, bridges and tunnels and is part of a plan to link South Mumbai with North with a toll-free freeway that is expected to ease up traffic in Mumbai, which is one of the most congested cities in the world.
It is the first undersea road tunnel in the country to pass through Arabian Sea near Girgaon Chowpatty and will start from Priyadarshani Park and end at Netaji Subhash Road in Marine Drive.
