Delhi Metro Phase 4: Milestone Reached with Tunnel Breakthrough on Golden Line

The Delhi Metro Rail Corporation marks a major milestone in its Phase 4 expansion with the successful completion of a 1.5-kilometer tunnel segment on the Golden Line between Kishangarh and Vasant Kunj stations. This achievement is critical to the Tughlakabad-Aerocity corridor, part of a larger 40-km underground network.

The Delhi Metro Rail Corporation (DMRC) announced a significant step forward in its ambitious Phase 4 expansion on Wednesday, following the successful tunneling of a crucial 1.5-kilometer section on the up-and-coming Golden Line.

A Tunnel Boring Machine (TBM) of 91 meters in length made a breakthrough at the under-construction Vasant Kunj Metro Station, marking a pivotal moment for the ongoing development of the Tughlakabad-Aerocity corridor.

This completion involved installing 1,105 concrete rings at depths averaging 23 meters using Earth Pressure Balancing, ensuring minimal impact on surrounding structures.
