Delhi Metro completes work of 4 km viaduct from Majlis Park to Mukarba Chowk
The Janakpuri West–RK Ashram Marg corridor of Phase 4 is expected to be completed by 2026.

The Delhi Metro Rail Corporation (DMRC) has successfully completed the structural work of 4 km of viaduct starting from Majlis Park to Mukarba Chowk, connecting the Majlis Park and Bhalswa stations on the upcoming Janakpuri West–RK Ashram Marg corridor of Phase 4. The construction of the corridor is expected to be completed by 2026.
Officials said this particular completed stretch of the elevated viaduct is now being offered to system contractors for track laying and traction work involving the erection of overhead electrification (OHE) masts etc. The structural work of the viaduct till Haiderpur Badli will also be completed soon, as just a crossing over a railway track is left.
The work on the Janakpuri West–RK Ashram Marg Metro corridor is progressing at full speed, said officials, adding that the DMRC completed 2.2 km of underground tunnels (for up and down movement) between Janakpuri West and Krishna Park Extension on this corridor last year.
On June 2, a tunnel boring machine was lowered for tunnelling work between Derawal Nagar to Pulbangash. This TBM drive will achieve a depth of up to 25.9 metres near the Najafgarh drain and 5,800 metres in diameter. The movement of the TBMs is being monitored round the clock digitally since there are a lot of old buildings above, said the DMRC.
As part of its Phase 4 expansion, the DMRC is currently working on constructing 65 kilometres of new lines across three different corridors. Out of these, 28 kilometres will be underground, and the rest will be elevated. There will be 11 new interchange stations under this expansion.
