Delhi Metro Breaks Ground on 12-km Underground Corridor Linking 7 Lines
The Delhi Metro Rail Corporation (DMRC) has commenced construction of a 12.377-km fully underground corridor between Inderlok and Indraprastha in Central Delhi. Announced on Thursday, the project is part of the network's Phase-IV expansion and is expected to significantly enhance cross-city connectivity.
The corridor will feature 10 stations and connect seven existing metro lines, making it one of the largest interchange routes in the system. Once operational, it will improve access to key locations including New Delhi Railway Station, Sarai Rohilla Railway Station, India Gate, Kartavya Path, Delhi Secretariat, and Arun Jaitley Stadium.
Passengers will be able to switch between the Red and Green lines at Inderlok, the Magenta Line at Nabi Karim, the Yellow and Airport Express lines at New Delhi, the Violet Line at Delhi Gate, and the Blue Line at Indraprastha. The proposed Sarai Rohilla station is also expected to serve educational institutions, commercial areas, and the Karol Bagh market.
As part of the expansion, the Magenta Line will be extended from Botanical Garden to Inderlok, bringing its total length to nearly 89 kilometres, making it the longest corridor in the Delhi Metro network. It will also have the highest number of interchange stations and will operate with driverless metro trains.
Construction work began at the proposed Sarai Rohilla Metro station with the building of a diaphragm wall, a key structural element for underground stations. Chief Minister Rekha Gupta was present at the launch. Other sections of the Magenta Line, including Janakpuri West to RK Ashram Marg, are also under construction. The Janakpuri West–Krishna Park Extension and Deepali Chowk–Majlis Park sections have already opened, with remaining stretches to be completed in phases.
