CMRL plans 26-km metro rail Corridor-4 extension

Chennai metro
The Chennai Metro Rail has decided to extend Corridor-4 from Poonamallee Bypass to Thirumazhisai Satellite Township. It is preparing a DPR for the 26-km long corridor from the existing stretch to the satellite township coming up in Thirumazhisai. Out of the total length, a four-km stretch will pass through the Chennai-Bengaluru Highway. Before this, Corridor-4 was planned from CMBT to Light House but now, it has been extended to Poonamallee, considering the increasing traffic congestion on Arcot Road along Virugambakkam and Valasaravakkam. The new stretch will have 12 underground stations, funded by the Asian Development Bank (ADB), from Light House to Meenakshi College, and 18 elevated stations from Meenakshi College to Poonamalee. The elevated stations will also be financed by the ADB. Chennai Metro Rail has invited bids for the construction of a 7.945 km elevated section from Porur Junction to Poonamallee Bypass and Larsen and Toubro is likely to get the tender from Meenakshi College to Porur.
