The Delhi Metro Rail Corporation (DMRC) has successfully completed the tunneling work between Netaji Subhash Place and Shalimar Bagh today by making a tunnel boring machine breakthrough at Shalimar Bagh.
The tunnel boring machine completed the tunneling of a 1,230 metre long tunnel from Netaji Subhash Place to Shalimar Bagh consisting of 1,025 rings with a diameter of 5.7 metres. Earlier, the same machine had completed another tunnel breakthrough in March this year on this section. The machine was lowered into launching shaft at Netaji Subhash place in April this year after retrieval and maintenance.
This tunnel also crossed the elevated viaduct of the currently operational Dilshad Garden - Rithala Metro corridor near Netaji Subhash Place, canal crossing and Kasturba Polytechic building, under construction elevated road at Shalimar Bagh etc. which were major engineering challenges.
This section is a part of 59 km long Majlis Park - Shiv Vihar corridor of Phase 3 consists of about 14 kms of underground lines.
