The Tamil Nadu state government has decided to extend the Chennai Metro Rail project by constructing three more lines as part of its efforts to expand the metro network to farther corners of the city. In his address to the assembly, governor Surjit Sigh Barnala said that “under the second phase of Chennai Metro Rail, a project study will be taken up for establishing new lines linking Moolakadai-Tirumangalam, Moolakadai-Tiruvanmiyur and Luz-Poonamallee via Iyyappanthangal.” Chennai Metro Rail will start detailed project report work in a month, and it will be completed in a year. The Moolakadai-Tirumangalam line will pass through Red Hills, Ambattur and Mogappair while the Moolakadai-Tiruvanmiyur line will pass through Perambur, Kilpauk, Gemini and Luz. The line from Luz to Poonamallee will cross Teynampet, T Nagar, Vadapalani, Saligramam and Iyyappanthangal. The routes have been identified based on a prima facie feasibility study, and Metro Rail is yet to finalise the alignment and stretches of the sections that will be underground and elevated. However, a senior government official said the Moolakadai-Tirumangalam line would be largely elevated, while the other two corridors would be largely underground. The state government’s plan to integrate the north-western belt of the city with the south through the additional lines is seen as a boon for the residents of Moolakadai, Poonamallee, Red Hills and Iyyappanthangal.
