The Asian Infrastructure Investment Bank (AIIB) will aid the second phase of the Chennai Metro project. ADB will fund Rs 2,306Cr to commence the 18-km long elevated structure of the project. The 18-km stretch between Meenakshi College and Poonamallee bypass is part of 26.1 km corridor of Chennai Metro’s phase 2 which will connect from Light House to Poonamallee Bypass. The total stretch of the Chennai Metro phase II is 118.9-km.
Earlier, the project executing body CMRL had planned to build corridor-4 between Light House and CMBT to link core areas of the city including Mylapore, Adyar, Nandanam, T Nagar, Kodambakkam and Vadapalani. Later, the CMRL planned to extend the corridor-4 to cover other areas like Porur, Iyappanthangal, Kumanan Cahvadfi, Karayan Chavadi, and Poonamallee, which were earlier planned to be connected through a monorail system, as the monorail project not feasible to handle the increasing passenger traffic.
