To facilitate access to any northern or southern part of the city from Poonamallee, Kattupakkam, Karambakkam, Porur and adjacent areas, Chennai Metro Rail Limited plans to invest Rs 61,843 crore under its Phase II project. Work on the project has begun on three corridors – Madhavaram to SIPCOT (Corridor 3), Light House to Poonamallee (Corridor 4) and Madhavaram to Shollinganallur (Corridor 5), with funding from state and federal governments as well as international Bank.
Metro trains under Phase 2 will allow commuters to switch seamlessly between the two sections, Corridor 4 and Corridor 5, as they will run parallel to each other for 5km. In this project, corridors 3 and 5 intersect at Shollinganallur and Madhavaram and again at Thirumayilai. But there are four transfer points in corridors 4 and 5 because the route runs about 5 kilometers in the same direction, with one corridor above the other. The double-deck section will include four stations – Alwarthirunagar, Valasaravakkam, Karambakkam and Alapakkam – built on two levels. Corridor No. 4 is located on the first floor, 13.5 meters above the ground. Corridor No. 5 is higher than this floor, with a height of 21 meters. The two sections will run for 5km using shared pillars and will have a common hall (ticket level) and two different platforms. This has the benefit of giving Porur commuters quick access to places like Adyar, Mylapore, Shollinganallur, Taramani, Madhavaram, Retteri, Majaambakkam and CMBT.
