Bangalore's peripheral areas all messed up? Blame it on Ribbon Development. Let me introduce you to a term very relevant to the congested sprawl that our city is witnessing. Simply put, Ribbon Development means building shops and houses along the roads radiating from a town. If you were to look at Bangalore from the skies and track recently laid or widened major arterial roads leading out of the city, you would notice that almost all big ticket construction/development happens solely along (rather right on top of) these roads.
Do me another favor. When on the periphery of Bangalore, try take a left or right out of any big radial road. This is most likely what you would see [pictures below]. Pathetic roads, poor quality of construction and even narrower streets if you were to venture into a "layout".
