CMRL has proposed a further extension of phase 2 by 93 km across various corridors.
Story so far: The construction of the Metro phase 2 has commenced across the city. The initial plan for phase 2 was 118.9 km with 128 stations. It was the longest stretch with 3 corridors. Now, there’s a proposal to extend this. One of the proposed extensions for phase 1 was between the airport and Kilambakkam, with working picking up.
- For corridor 3 (Siruseri to Kilambakkam Bus Stand), the extension will be 26 km. The extension of corridor 4 (Poonamalle to Parandur, site of the new airport) will be 50 km.
- For corridor 5 (Koyambedu to Avadi via-Thirumangalam and Mogappair), the extension will be 17 km. Consultants will be finalised by October to study the feasibility.
