Navi Mumbai is a planned township in Mumbai on the west coast of the Indian state of Maharashtra. It was developed in 1972 as a new urban township of Mumbai, and is the largest planned city in the world. The population of Navi Mumbai has reached 1,119,477 as per the 2011 provisional census.
Navi Mumbai, located in the eastern trans harbour of Mumbai, Maharashtra, is one of the world's largest planned townships. Since independence, the decision to build a new city on the mainland across the harbour was for a specific purpose: to decongest Mumbai, an island city whose physical expansion had a limit. It was also earmarked as an alternate haven for the multitudes that thronged to Mumbai from all over India. This decision required the state government to exercise the matching, politically speaking, hard option to relocate its seat of governance along with all its important offices to this new city, and completely stop the backbay reclamation project in the island city. It did nothing of the sort. It continued with the reclamation and put brakes on the efforts of CIDCO (such as the shifting of wholesale markets).
The planning of Navi Mumbai could begin, in the right earnest, only by 1971, and involved leading architects and urban planner like, Charles Correa (Chief Architect), Shirish Patel, Pravina Mehta and R. K. Jha (Chief Planner), South Navi Mumbai is being developed rapidly with its class infrastructure and modern nodes of Kharghar, Kamothe, New Panvel and Kalamboli.
The City and Industrial Development Corporation (CIDCO) was formed on 17 March 1971, under the Indian Companies Act, 1956. The area covered of the total of the Konkan coast. Privately owned land conisisting of 86 villages covering within the present limits of Navi Mumbai and further villages measuring an additional were acquired by the government of Maharashtra.
CIDCO carved out 14 nodes small townships with a view towards facilitating comprehensive development. These nodes are named Airoli, Ghansoli, Kopar Khairane, Vashi, Sanpada, Nerul, CBD Belapur, Kharghar, Kamothe, New Panvel, Kalamboli, Ulwe, Dronagiri, Taloja.
CIDCO planned and constructed all the railway stations in Navi Mumbai and developed nearby areas commercially.
By the end of the 1990s, the planning authority of Navi Mumbai initiated private participation in the developmental activity of Navi Mumbai.
A new railway link between Nerul and Uran is under construction and the portion of this line from Seawood to Ulwe is at an advanced stage of construction. Kharghar and Panvel are experiencing major infrastructural developments due to their proximity to the proposed Navi Mumbai International Airport.
