Tamil Nadu Government has announced that a detailed project report for extending the metro line from the airport to Kilambakkam is underway. An elevated line covering 15.3km will link the airport at Meenambakkam with Kilambakkam through stations at least 13 locations. The line will link several densely populated suburbs like Pallavaram, Chromepet, Tambaram, Perungalathur, and Vandalur and may run parallel to the suburban train network and will also link several landmarks like Tambaram railway station, Arignar Anna Zoological Park at Vandalur and the moffusil bus terminus coming up at Kilambakkam. When the construction of phase-2 metro rail project is completed, passengers from southern suburbs like Pallavaram and Tambaram could travel to Madhavaram in the northern suburbs via the airport. Locals in suburbs want the government to expedite work to build a metro line to link Tambaram with Velachery to ease travel for those living in the ECR and OMR IT corridor. CMRL is linking the OMR IT corridor from Thiruvanmiyur to Siruseri SIPCOT in phase-2 project.
