Chennai Metro plans to extend Corridor-4 to Thirumazhisai Satellite Township

Chennai, India (Urban Transport News):  The Chennai Metro Rail Limited (CMRL) is planning to extend Corridor-4 (Light House - Poonamallee Bypass) of the Chennai Metro Rail project from Poonamallee Bypass to Thirumazhisai Satellite Township. The 4-km stretch from Poonamallee Bypass to Thirumazhisai Satellite Township will pass through the Chennai-Bengaluru Highway.

AECOM has been given the responsibility to prepare a detailed project report (DPR) on extending the 26-km Corridor-4 from the existing stretch to the Thirumazhisai Satellite Township. 

Initially, the CMRL had planned to connect CMBT to Light House under its Corridor -4 but later it has been extended to Poonamallee, considering the increasing traffic congestion on Arcot Road along Virugambakkam and Valasaravakkam. The stretch will have 12 underground stations from Light House to Meenakshi College, and 18 elevated stations from Meenakshi College to Poonamalee. The construction cost of the underground stretch will be funded by the Asian Development Bank (ADB) whereas the cost of elevated stations by the Asian Infrastructure Investment Bank. 

CMRL has invited tenders for the construction of a 7.945 km elevated section from Porur Junction to Poonamallee Bypass. Larsen and Toubro (L&T) has emerged as the lowest bidder for the construction of the Meenakshi College to Porur section. Poonamallee will be one of the five depots of the Chennai Metro Rail Project and a separate tender will be awarded for setting up the depot at  Poonamallee. The other depots will be set up at Siruseri-Sipcot, Madhavaram and Wimco Nagar.  Koyambedu is one of the existing depots which is feeding metro trains for Phase I.

According to the approved plan, Corridor-4 will connect Light House with Poonamallee Bypass through 30 metro stations.
