Recently, Chief Minister Jayalalithaa laid foundation for the Metro Phase I extension project. Chennai Metro Rail will soon start tunneling work for the Phase I extension project from Washermanpet to Wimco Nagar. The Phase I extension of Chennai Metro Rail will cover a 9-km stretch from Washermanpet to Wimco Nagar. The stretch from Washermanpet to Korukkupet will be underground.
The rest of the stretch will be elevated.
The project that is estimated to cost Rs. 3,770 crore is a 9 km stretch which is partly underground and partly elevated. Chennai Metro Rail plans to complete the underground stretch first as it is a time-consuming project. Few months ago, Afcons Infrastructure Limited was awarded the contract for the work.
