The Light House-Poonamalle corridor of Phase II of Chennai Metro is set to be developed as a partial underground and rest overground route. The line from Light House to Meenakshi College stations will be underground and then be elevated to Poonamallee.
Two viaducts are also planned over existing structures at Vadapalani by Chennai Metro — the first one is the flyover at Jawaharlal Nehru Salai intersection and the second one at its Phase I line running from Koyambedu to Alandur via Vadapalani.
“The detailed project reports (DPR) for the stretch from Light House to Meenakshi College and from Valasarawakkam to Poonamallee is ready; these two DPRs will be combined and made into one. A detailed design consultant (DDC) will soon start work for the stretch from Light House to Meenakshi College, and they will decide where exactly the stations will be located, the land required for stations and other facilities and other specifics of the project and the work will start first for this stretch. Subsequently, a DDC will be appointed for the Poonamallee stretch too, and work will be taken up,” as quoted by The Hindu.
The report further adds that the Chennai Metro’s Light House to Meenakshi College stretch is likely to be funded by the Asian Development Bank.
