Location

Poonamallee Bypass metro station is an upcoming elevated metro station on the Yellow Line of the Chennai Metro. This metro station will be among the 30 stations of corridor IV and 18 elevated stations along corridor IV of the Chennai Metro, Poonamallee Bypass–Lighthouse stretch. The station serves the neighbourhoods of Poonamallee.

In January 2021, Chennai Metro Rail Limited (CMRL) began the bidding process for the construction of this Poonamallee Bypass metro station, that spans between Poonamallee Bypass and Porur Junction, a 7.945 km segment forming Corridor 4 within Phase 2 of the Chennai Metro project.

The contract, designated as Package C4-ECV-02, drew prominent interest from a number of prominent infrastructure firms, including Larsen & Toubro (L&T), Tata Projects, Afcons Infrastructure, and lastly with ITD Cementation India Ltd. Following a quite thorough evaluation of all of the technical submissions along with financial bids, Larsen & Toubro (L&T) was declared the lowest bidder, with its proposal meeting both engineering requirements along with cost parameters set by CMRL. Subsequently, the contract was awarded in full to them. Construction of the station began in 2021. The construction is being funded by Asian Infrastructure Investment Bank.^[1] Following the award, they initiated work in line with the project's approved blueprint and execution plan. ^[2][3]

The Poonamallee Bypass metro station will feature a depot, which will be one of the five depots of the Chennai Metro.^[1] Built at a cost of ₹2,250 million, the depot will have 24 tracks^[4] and will be used for the repair, maintenance and cleaning of trains and will exclusively serve the trains to be operated on the Poonamallee–Light House stretch.^[5] The depot will feature ballast tracks to save on capital expenditure, since laying ballastless track my cost an additional ₹800 to 900 million.^[4]
