The proposed Phase-2 of the Gurgaon Metro project may shift from an elevated to an underground alignment, a move that could nearly double its overall cost and delay completion. Officials are considering the redesign to reduce land acquisition challenges and minimise disruption to densely populated areas.

Sources indicate that the project’s cost could rise significantly due to tunnelling, safety systems, and advanced construction requirements associated with underground corridors.

The Haryana Mass Rapid Transport Corporation is currently assessing revised design proposals and financial implications before final approvals. The 28-km corridor aims to enhance connectivity between Gurgaon’s new sectors and the Rapid Metro network, improving regional mobility.
