Outline Features of Phase-II of the Chennai Metro Rail Project


The foundation stone for Phase II of Chennai Metro Rail Project – estimated at a cost of Rs.61,843 crores - was laid through video conferencing on 21-11-2020 at Kalaivanar Arangam.   CMRL’s Phase-I project covering two corridors for 45 kms from Washermanpet to the Airport on the Blue Line and from Puratchi Thalaivar Dr. M.G. Ramachandran Central Metro to St. Thomas Mount on the Green Line with a total of 32 Metro Stations has been successfully completed and is in operation. CMRL is the first Metro Rail System in India to connect the city’s Railway Terminal, Bus Terminals and Airport as part of the first phase.   

The Phase-I Extension of the project from Washermanpet to Thiruvottiyur (Wimco Nagar) covering 9.051 km with 8 Metro Stations (2 Underground and 6 Elevated Metro Stations) will connect the northern part of the city to the Central Business District Area and is targeted to be opened for traffic by the end of January 2021.

The demand for a fast, safe, efficient and sustainable public transport system means that CMRL’s Phase-II project is being planned for 118.9 kms in three corridors. Corridors 3, 4 and 5 will be at an estimated cost of Rs. 61,843 Crores and will be supported by Government of India, Government of Tamil Nadu, JICA, ADB, AIIB and NDB.

A total of 23 TBMs are expected to be used in the Phase-II of the CMRL Project for the boring of the Twin Tunnels. The Phase-II of CMRL Project is the first Metro in India and will be the Single Largest Metro Rail Project to be implemented in one stretch.

With the completion of these 3 corridors by 2026, Chennai will have 173 km of metro stretch carrying 25 lakh (million) passengers per day accounting for 25% of public transport trips, to transform the country into a world-class destination for investments and economic activities.

As part of Multi-Modal Integration, the Phase-II Network will be integrated with other public transport modes namely Suburban Rail, MRTS, City Bus service, etc. at 21 different locations to ensure hassle-free and seamless connectivity.  For further information click in/40 for tunnelbuilder archive.
