A spokesperson for the Chennai Metro Rail Limited (CMRL) stated that Phase 2 of the Chennai Metro Rail project has been completed for a total of 20 km in various parts of the city and suburbs, connecting at least 25 localities. The spokesperson explained that construction on the project began three and a half years ago, and consists of the corridors' upline and downline portions, spanning 10 km above ground and 10.77 km underground. It is noted that there are three corridors in the 116.1 km Phase 2 with 118 stations, one of which is a 42.6 km subterranean segment connected by 45 stations.

The spokesperson further stated that the lines are being installed in small sections on a piecemeal basis. The spokesperson quoted a CMRL official as saying that "Construction of around 47 stations is also underway. At some stations, the entry/exit work is underway and in some other stations, construction of substructure or superstructure is in progress. They are in various stages." It is seen that the elevated viaducts and underground tunnels have connected Manapakkam, Mugalivakkam, Ramapuram, Kovilambakkam, Perumbakkam, Porur, Thelliagaram, Iyyappanthangal, Kattupakkam, Poonamallee, Alapakkam, Shastri Nagar, Retteri, PTC Colony, Okkiyampet, Karapakkam, Okkiyam Thoraipakkam, Vadapalani, Madhavaram, and Venugopal Nagar to each other.

It is noted that according to M A Siddique, CMRL's Managing Director (MD), Phase 2 would be completed in stages between 2026 and 2028. The spokesperson said the length connecting Porur and Poonamallee is expected to be the first to open before the end of 2025, and the Thirumayilai metro, which will serve as an interchange between corridors 3 and 4, and the stations nearby, will be the last to open in 2028. The spokesperson acknowledged that in parts of certain already-barricaded regions, like OMR and Mylapore, construction has not yet started. The spokesperson stated that due to issues with contract awarding, OMR's work on the segment from Sholinganallur to Siruseri SIPCOT was stopped, but the CMRL authorities have said that OMR construction will shortly get underway. The spokesperson also noted that officials in Mylapore claimed work on one part had been halted after some shopkeepers filed a judicial challenge to their eviction order.
