The city is named after three villages that share the same name, which are among the 124 villages in Raigad district, collectively known as the Third Mumbai.
Navi Mumbai: The Mumbai Metropolitan Region Development Authority (MMRDA) officially named the Third Mumbai as Karnala-Sai-Chirner New Town (KSC New Town)
The MMRDA has been officially appointed as the New Town Development Authority (NTDA) of the city, a governing body that plans new towns in India. A final decision on the same was taken on October 15 with the Maharashtra government issuing three notifications towards the same. “…to improve connectivity and reduce travel time between Mumbai and Navi Mumbai, MMRDA has developed Shri Atal Bihari Vajpayee Trans Harbour Link, which is expected to have a major positive impact on the economic development and growth of the region…” reads one of the notifications issued by the Urban Development Department.
In August 2023, MMRDA had requested the state government to appoint itself as NTDA for the MTHL Influence Area. This request was to make the MTHL project economically viable by capturing the land value enhancement of the MTHL landing and influence area. The 21.8 km long sea link, India’s longest, has been built at a cost of ₹17,843 crore. This August, 7,25,746 vehicles plied on the bridge.
