A massive five-year plan is under way for setting up a metro rail project in Chennai. Estimated to cost Rs 5,086.85 crore, the first phase of the project is to be completed by 2010. It will cover 31.54-km from Tiruvottiyur to the airport through Anna Salai and the 13.54-km stretch from Chennai Beach to Koyambedu along the EVR Periyar Salai. The Tiruvottiyur-airport segment would have 8.4 km underground system and the rest in an elevated system in the central median. An additional network, from Thiruvanmiyur to Ambattur through Luz, Nandanam, and T Nagar, also is proposed. However, the work for that is to be taken up after 2016 only.
