If you come into Chennai by air, your drive to the city will almost invariably face a bottleneck at the Kathipara junction. That's the point where the Grand Southern Trunk Road, Mount Poonamallee Road and the Jawaharlal Nehru Road meet up. But the bottleneck is not just about traffic; the grade separator at this junction, though nearly complete, currently contributes to a small part of the holdup.

A small part, now that the free-flow link between JN Road and GST Road has been open for a month. This photo was taken when going under that link, towards JN Road. In less than a year, those mounds of earth would have been replaced by greenery; all the links are expected to be operational before April 2009. And then, one can whiz through from the airport into the city in no time at all!

(Oh, yes. Traffic volume will still be a factor in your whizzing.)
