Chennai city has the largest number of flyovers and subways. Traffic in the city move at a speed of 22km/hr which is reasonably good when you compare this data with other major cities of the country. Major bottlenecks have been cleared with the construction of flyovers (actually, it should have been done much earlier anyway, better late than never).
Inspite of so many flyovers , still, ther is no answer for the traffic jam at Panagal park junction.That locality houses many major jewellery marts and textile shops. The planners of the late 70's did not envisage the future growth of the city. As a result, the subway at duraiswamy Road is very narrow and it is unable to take the load of burgeoning traffic of the city. Situation is very similar at Madley road subway too. The approach roads to this subway is very narrow and that area would need removal of residential colonies Which is not feasible in today's condition.
