Mumbai just got itself a new reason to celebrate, the Mumbai’s Aqua Line, officially known as the Mumbai Metro Aqua Line 3, is finally open, and it’s a big one. Stretching 33.5 km from Aarey to Cuffe Parade, it’s India’s longest underground metro, built to connect the suburbs directly with the heart of South Mumbai.
After nearly a decade of construction, trial runs, delays, and anticipation, the city finally saw its most ambitious metro corridor come alive. And Mumbai didn’t disappoint, on day one of full operations, over 1.46 lakh people took the ride. That’s not just a number; it’s proof that Mumbaikars were waiting for this line like monsoon rain after summer.
The Mumbai Metro Line 3, or as people call it, Mumbai’s First Underground Metro, links major business and government zones, from the green edge of Aarey right down to the Arabian Sea.

Earlier? About 1 hour 22 minutes and ₹800 if you dared to take a cab.
