NEW DELHI — Construction of Delhi Metro Phase 4, a 65.1-kilometre expansion across six corridors connecting underserved parts of the capital, officially began on Monday with simultaneous ground-breaking ceremonies at eight construction sites, marking the most significant expansion of the Delhi Metro network since Phase 3 in 2014.
What Phase 4 Offers
The new network will feature 45 stations, all equipped with platform screen doors, real-time air quality monitoring, solar panels, and full accessibility infrastructure for persons with disabilities. When complete, it will extend metro coverage to colonies including Lajpat Nagar, Saket G-Block, Tughlakabad, Inderlok, and Punjabi Bagh West.
DMRC Managing Director Vikas Kumar said the expansion would reduce the average peak-hour commute time between South Delhi and the city centre by 35 minutes. "This is not just an infrastructure project. It is a social equity project — bringing reliable, affordable mobility to Delhi's residents who have long been left behind by the metro network," he said.
Green Infrastructure
All Phase 4 stations will be built to IGBC Green Building Gold standards, with rooftop solar installations expected to meet 70% of the network's daytime energy needs. The project will also feature India's first metro-integrated cycle-sharing hubs at 30 stations.
