Delhi: DMRC completes first tunnelling drive on Phase 4 Metro corridor
The Delhi Metro Rail Corporation (DMRC) on Friday said it has completed constructing a 1.4km long tunnel at the Krishna Park Extension–the first ever tunneling stretch on the Janakpuri West – RK Ashram Marg corridor–with the help of a tunnel boring machine (TBM).
The main tunneling work on the stretch commenced in April this year and met several constraints due to the Covid-19 pandemic and the associated lockdowns. The tunnel breakthrough achieved on Friday was done using a 73-metre long TBM, in the presence of DMRC’s managing director, Dr. Mangu Singh, along with other senior officials.
Currently, two parallel circular tunnels are being constructed for up and down movement on this stretch, which is part of the 2.2km long underground section from Janakpuri West to Keshopur. DRMC officials said tunneling work on the other parallel tunnel will commence soon.
