Polycentric satellite to decongest Bombay
Large-scale counter-magnet strategy
Navi Mumbai (New Bombay), planned from the late 1960s and developed by the state corporation CIDCO, followed a concept advanced by Charles Correa, Shirish Patel and Pravina Mehta to build a counter-magnet city across the harbour from Bombay. The plan proposed a polycentric string of nodes along mass-transit lines on the mainland, each with its own centre and employment, intended to draw population and offices away from the congested island city.
Navi Mumbai is among the largest planned new cities of the twentieth century and the most ambitious Indian attempt to restructure a metropolis through a twin city rather than incremental expansion. Its node-and-corridor form influenced later Indian urban projects, while the slow migration of jobs across the harbour has made it a standard case in debates about whether counter-magnets can genuinely redirect metropolitan growth.
