Bombay has a lot of "flyovers"-- the word used around here for overpasses.  I guess they must relieve traffic problems, but just barely.  Its still really really crowded and slow during rush hour on most major roads.  Here's an interesting statistic from the book I'm reading currently, Maximum City.  Only 32% of Bombay metropolitan area residents live on the island that is referred to as South Bombay.  42% live in the northern suburbs, and 18% live in New Bombay (Navi Mumbai).  But 72% of jobs are in South Bombay.  Which means that no matter how many flyovers you have, you're not going to alleviate the basic issue of millions of people commuting into and out of one very small area on a daily basis.

This particular flyover is right above Mohammad Ali road, which is the major road close to where I live.  Its called the JJ flyover.  I took this picture from Mamajee Yousuf's apartment (I live within walking distance of his building).
