The Delhi Metro Rail Corporation (DMRC) has achieved a significant milestone by completing the structural work of a 4-kilometer viaduct section from Majlis Park to Mukarba Chowk. This section connects the Majlis Park and Bhalswa Metro stations, forming a part of the upcoming Janakpuri West–RK Ashram Marg corridor in Phase-4.

The completion of this elevated viaduct segment marks an important progress, as it now allows the system contractors to proceed with the track laying and traction work, including the installation of Over Head Electrification (OHE) masts. Furthermore, the remaining structural work for the viaduct, up until Haiderpur Badli, is nearing completion, with only a railway track crossing left to be constructed.

This achievement holds significant value for the DMRC’s engineers, considering the challenging circumstances under which the corridor construction commenced amidst the Covid crisis. Despite facing intermittent delays due to the pandemic and issues related to obtaining tree-cutting clearances, the work on this corridor has been executed without causing major disruptions to the traffic flow below.

The construction of this corridor is expected to be completed by March 2026. The DMRC continues to make substantial progress on the Janakpuri West–RK Ashram Marg Metro corridor, with the completion of 2.2 kilometers of underground tunnels between Janakpuri West and Krishna Park Extension last year.

In recent developments, on June 2nd, another tunnel boring machine (TBM) was deployed for tunnelling between Derawal Nagar and Pulbangash. This TBM will dig to a depth of 25.9 meters near the Najafgarh drain, with a diameter of 5,800 meters.

The DMRC is actively monitoring the movement of the TBMs digitally round the clock, as there are numerous old buildings located above the tunnels. This ensures the safety and structural integrity of the surrounding structures during the tunnelling process.

As part of its Phase 4 expansion, the DMRC is currently engaged in constructing 65 kilometers of new lines across three corridors. Out of these, 28 kilometers will be underground, while the rest will be elevated. Additionally, the expansion includes the establishment of 11 new interchange stations.

It is worth mentioning that all the information provided has been compiled through extensive research, and the article aims to provide a concise summary of the developments in the Delhi Metro’s Phase-4 project on the Janakpuri West–RK Ashram Marg corridor.
