Suburbanisation - Mumbai

The population of Mumbai has recently reached 23 million.

Mumbai has been effected by the process of suburbanisation to large degree.

What is suburbanisation?
The outward movement of a city. The periphery extending, increasing the size of the urban sprawl

In LEDCS like India the urban sprawl is not kept in check by policies such as 'green belts', the process is more unplanned/out of control.

-The first movement of suburbanisation was Northwards along traffic corridors
-Now it is spreading eastward in direction with the building of the Vashi bridge across Thane Creek - the number of lanes the bridge has is set to double to 12 lanes of traffic

Now less than a third of the population lives in the 'island' city.
The centre of population has now shifted to suburban area of Salsette
-Commuter traffic is now less 'one directional', it not only flows into the CBD, movement in the opposite direction is substantial
-Few suburban residents seek the markets at the South of the city and Southern universities and schools are facing dropping numbers of students
-The suburbs are becoming 'edge cities', increasingly self supporting
