Navi Mumbai, located in the eastern harbour of Mumbai, is one of the world's largest planned townships. Since independence, there was a specific reason to build a new city on the mainland across the harbour: to lower the population of Mumbai, an island city whose physical expansion had a limit. It was regarded as an alternative for the many people who wanted to come to Mumbai from all over India. This decision required the Maharashtra government 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 not do this. It continued with the reclamation and put brakes on the efforts of CIDCO (such as the shifting of wholesale markets).
