As part of the second phase extension of the Chennai MRTS network from
Velachery to
St. Thomas Mount, Adambakkam station was expected to be opened in 2013, but construction faced multiple delays due to land acquisition issues and legal hurdles. With the court dismissing all the cases against land acquisition for construction, the station was expected to be completed by the end of 2024, but multiple deadlines were revised. With the commissioning of Velachery - St. Thomas Mount stretch of MRTS on 14 March 2026, Adambakkam station was set to open but got delayed. The stoppage at the station is currently skipped for operational reasons. ==Structure==
