The Delhi Metro Rail Corporation (DMRC) today completed the construction of an underground tunnel between Maa Anandmayee Marg and Tughlakabad Railway colony station on the Tughlakabad-Aerocity corridor of Phase-IV, which is also known as the Golden Line.
The breakthrough of the Tunnel Boring Machine took place in the presence of the Minister for Transport of the NCT of Delhi, Dr. Pankaj Kumar Singh. Managing Director of DMRC and other senior officials were also present.
This new tunnel has been constructed at an average depth of approximately 18 meters. About 566 rings have been installed in the tunnel, with an inner diameter of 5.8 meters.
The Golden Line, part of Phase 4 of the Delhi Metro expansion, aims to improve connectivity in the city’s southern parts. The corridor will link Aerocity, a major transit hub near the Indira Gandhi International (IGI) Airport, with Tughlakabad. Approximately 19.343 km of the approved 40.109 km corridor is underground.
