Kalkaji Mandir metro station
The Kalkaji Mandir metro station is an interchange station between the Violet Line and the Magenta Line of Delhi Metro. It serves the area of Kalkaji in South-East Delhi, and provides access to many tourist sites such as Kalkaji Mandir, Lotus Temple, Prachin Bhairav Mandir and ISKCON Temple. The station was opened along with the first section of the Violet Line from Central Secretariat - Sarita Vihar on 3 October 2010, in time for the Commonwealth Games opening ceremony on the same day. Its interchange with the Magenta Line was opened on 25 December 2017.
The Violet Line station is elevated while the Magenta Line station is underground. Both of these are connected by a 260 m (850 ft) long pedestrian bridge. The underground station is situated at a depth of 17 m (56 ft) and both of its tracks pass through a single-tube twin tunnel, which was constructed using the New Austrian tunneling method (NATM). This had to be done because the station had to pass beneath the operational Violet Line.
