Overview

• On June 7, a 96-metre TBM bored a 0.792-kilometre tunnel between Maa Anandmayee Marg and Tughlakabad Railway Colony Station on the Golden Line.
• The tunnel sits about 18 metres below the surface, spans 5.8 metres in diameter and is lined with 566 precast concrete rings cast at Mundka’s mechanised yard.
• Construction used the Earth Pressure Balancing Method and continuous ground monitoring to prevent settlement under existing structures.
• This segment is part of the 19.343-kilometre underground stretch on the Tughlakabad–Aerocity corridor within Phase IV’s 40.109 kilometres of new tunnels.
• Transport Minister Pankaj Kumar Singh praised the achievement as evidence of renewed momentum and set a target for the parallel tunnel’s completion by July 2025.
