India's Longest Flyover- 4 Lanes.....is it enough ?

Read on rediff.com that India is soon going to have their longest flyover ( 11.2km ) in Hyderabad.I am not sure when would we really start thinking ahead of time. India is growing fast and with cheaper cars coming into the market, is it really a smart move to just build a 4 lane flyover? What after 5 years we realise that this flyover is not meeting the traffic need and we need to expand more. Are we again going to take up new expansion project ? I do feel happy that something is getting done, but we need to think ahead of time. We need to start building 8 lanes considering the rising traffic of India. 4 Lanes may work right now, but would cause bottleneck in future.

Just my 2 cents
