The Maharashtra government alongside the Mumbai Metropolitan Region Development Authority (MMRDA) is developing a world-class greenfield smart city spanning 124 villages across Raigad district to relieve acute pressure on Mumbai and Navi Mumbai. Officially designated as the Karnala-Sai-Chirner (KSC) New Town, the project—popularly dubbed 'Third Mumbai' or 'Mumbai 3.0'—aims to establish an international business and logistics destination modeled on global hubs such as Singapore and Hong Kong.
Singapore-based urban development consultancy Surbana Jurong is preparing the master plan for the mega-city, which was formally announced at the World Economic Forum in Davos.
What Happened
Spanning 323.44 square kilometres across Uran, Pen, and Panvel talukas, KSC New Town will integrate 124 villages into a high-tech urban ecosystem. Under the master plan, 104 square kilometres are earmarked for modern townships, commercial districts, and industrial corridors. The remaining area will be preserved as forest land, green belts, and traditional rural settlements.
The project operates as a tripartite venture involving private developers, the Maharashtra state government, and the MMRDA. Land pooling and Mumbai 3.0(TP) scheme processes are currently underway. Phase 1, focusing on foundational utilities, road links, and connectivity to the upcoming airport, is expected to become operational between 2028 and 2030, with full completion targeted for 2040.
City / Region | Total Area | Current / Projected Population (by 2040) |
Mumbai 1.0 (Original City) | 437.71 sq km | 1.5 crore |
Mumbai 2.0 (Navi Mumbai) | 343.70 sq km | 15–20 lakh (Projected: 35–40 lakh) |
Mumbai 3.0 (KSC New Town) | 323.44 sq km | Designed for 25–30 lakh |
Total MMR Region | — | Projected 3.5 crore |
Why It Matters
Rapid population growth and soaring real estate prices have saturated both Mumbai and Navi Mumbai, leaving little room for expansive commercial or industrial development. Third Mumbai addresses this spatial deficit by introducing a '15-minute city' model, where residential areas, workplaces, schools, and medical facilities are situated within a 15-minute commute to minimize traffic congestion.
Economically, the development is designed as an aerotropolis and port-based trade hub due to its proximity to the Jawaharlal Nehru Port Trust (JNPT) and the Navi Mumbai International Airport. The ecosystem is projected to generate daily employment for 10 to 15 lakh workers, featuring financial centres modeled on the Bandra-Kurla Complex (BKC), IT parks, data centre clusters, and global educational hubs.
Background Context
The project builds upon major transit infrastructure investments designed to integrate the Mumbai Metropolitan Region (MMR):
- Atal Setu (MTHL): The 21.8 km sea link connects South Mumbai to Raigad in 20 to 25 minutes.
- Navi Mumbai International Airport (NMIA): Positioned adjacent (0.25 km) to the KSC New Town border, serving as its primary global transit hub.
- Panvel-Karjat Rail Corridor: Connects the new township directly to the Mumbai suburban railway network.
- Virar-Alibaug Multimodal Corridor: Enables North-South regional connectivity across the MMR.
- Mumbai-Pune Expressway: Provides rapid road access to Pune and Western Maharashtra.
What Comes Next
With land acquisition and town planning schemes moving forward, state authorities are prioritizing initial utility frameworks for water, electricity, and arterial roads. As Phase 1 nears its 2028–2030 operational target, the project is positioned as a primary driver of Maharashtra's economic strategy, supporting broader national goals toward a $5-trillion economy through sustainable, transit-oriented urban planning.
