Description
Description | Delhi Metro has achieved a significant milestone in its Phase IV expansion with the successful breakthrough of an underground tunnel on the Aerocity-Tughlaqabad corridor, also known as the Golden Line. The project involves constructing two parallel circular tunnels using a 96-metre-long tunnel boring machine (TBM) to facilitate metro movement. The first tunnel of 0.79 km has been completed, with the second tunnel expected to be completed by July 2025. The tunnels are constructed at an average depth of 18 metres using earth pressure balancing technique and precast concrete rings for structural integrity. This corridor is part of a larger 19.34 km underground rail line aimed at enhancing connectivity and easing traffic congestion in Delhi. |
