Third Mumbai — also known as Mumbai 3.0 — is a planned smart city region envisioned as the next major phase of urban development following South Mumbai (Mumbai 1.0) and Navi Mumbai (Mumbai 2.0)
More than just an extension, it represents a forward-looking development corridor that seamlessly integrates infrastructure, industry, housing, and commerce. Strategically located in Raigad district, it spans across the Uran, Panvel, and Pen talukas, and lies in close proximity to the Atal Setu and the Navi Mumbai International Airport.
Third Mumbai, also known as Mumbai 3.0, is not a single city but a strategic development zone located south-east of Mumbai, primarily covering:
- Navi Mumbai South (Ulwe, Dronagiri, Pushpak Nagar)
- Raigad District (Panvel, Uran, Pen, Karjat, Khalapur)
- NAINA Region (Navi Mumbai Airport Influence Notified Area)
- Areas surrounding major projects like:
- Navi Mumbai International Airport (NMIA)
- Mumbai Trans Harbour Link (Atal Setu/MTHL)
- JNPT Port and Logistics Hub
- Upcoming Metro lines, IT parks, and data centers
Why Is It Called “Third Mumbai”?
- Mumbai 1.0: The original city — South Mumbai and the Island City
- Mumbai 2.0: Planned Navi Mumbai (CBD Belapur, Vashi, Airoli)
- Mumbai 3.0 / Third Mumbai: The next phase of urban expansion — emerging from the new international airport, major expressways, Atal Setu, and large-scale zoning for residential, commercial, and industrial use
What Makes Third Mumbai Important?
- NMIA: One of India’s biggest upcoming international airports
- Atal Setu (MTHL): India’s longest sea bridge connecting Mumbai to Navi Mumbai in under 25 minutes
- CIDCO & NAINA Masterplans: Smart city planning with industrial, IT, residential & logistics zones

- Excellent connectivity: Through highways, metro rail, and sea links
