CHENNAI: A Detailed Project Report (DPR) has been prepared for three Metro Rail Corridors in the second phase covering a total of 107.5km, included under Japan Investment Corporation (JICA) Rolling Plan.
The three corridors are: Madhavaram to Siruseri (45.77km), Madhavaram to Sholinganallur (44.66km) and CMBT to Light House (17.12km). This was disclosed by Finance Minister D Jayakumar while presenting the State budget.
Of the 107 km plus stretch, more than half would be underground and the remaining elevated. The total cost as per the feasibility report is estimated at `42,000 crore. The cost of the underground stretch is `32,000 crore while the elevated stretch is `10,000 crore. But, sources indicate it could increase or decrease.
The feasibility report claims that the project is likely to be completed by 2026.
The Corridor 3 starts from Madhavaram at the northern end and runs up to Siruseri at the southern end for a distance of 45.77 km. It connects important centres such as Moolakadai, Perambur, Purasawalkam, Kilpauk Medical College (KMC), Gemini, Luz, Adyar, Tiruvamiyur, Perungudi, Karappakam, Sholinganallur, and Navalur.
Interestingly, the feasibility report has identified the 19.3km stretch between Madhavaram and Adyar as underground stretch while 20.9km stretch between Adyar to Siruseri would be elevated.
A constraint for the elevated portion of the third corridor is that the crossing of Buckingham Canal in Lattice bridge might require land acquisition.
Similarly, Corridor-4 starts from Lighthouse and runs up to CMBT for 17.2 Km. It will connect important places like Luz, Nandanam, Vadapalani and CMBT. The corridor can be extended to Sriperumbudur after 2035 based on the growth trend.
The 44.6 km-long corridor-5 is an orbital one starting from Madhavaram and ending at Sholinganallur. Significantly, it connects important places like Madhavaram,Villivakkam, Ambattur Industrial Estate, Nerkundram, Ramapuram, OTA and Medavakkam.
