A DPR, or Detailed Project Report, for Phase II of the Chennai Metro Rail project has been submitted to the Tamil Nadu State government.
Officials of the Chennai Metro Rail Limited, or CMRL, say, RITES, the firm which prepared the DPR, recently submitted the document to us. Subsequently, we have forwarded the DPR to the State government for approval. Soon after we get a nod from the State, it will be forwarded to the Centre after which the project can begin.
According to sources, Most of the project would be underground and the elevated section would be confined to a few short stretches. Some parts emerging from Kandhanchavadi to SIPCOT may be elevated. The rest would be underground. This is not final yet. It can be changed even at the last minute. The present cost is Rs. 44,000 crore. This will also change depending on how much of the stretch is underground.
Speaking about this, officials said, If more portions of the project are underground, we expect the cost of the project to go up. While the elevated corridors cost about Rs. 150-200 crore per kilometre, underground rail works out to about Rs. 500 crore per kilometre. The length of the corridor too may be extended by a few kilometers.
Phase II of the project comprises three corridors running to 104 km covering 104 stations. The corridors are - Madhavaram Milk Colony to SIPCOT for 44.3 km, via Padi, Valasaravakkam and Medavakkam, CMBT to Light House for 15.7 km and Madhavaram Milk Colony to Sholinganallur for a stretch of 44.6 km, via Perambur, Luz, Adyar and ECR.
