New Delhi: Delhi Metro on Thursday commenced tunneling work on the upcoming Janakpuri West Botanical Garden corridor at Palam. "The crucial 1.5 km stretch of the upcoming Janakpuri West Botanical Garden corridor at Palam, will play a major role in connecting areas like Janakpuri, Dabri, Palam with important locations such as the IGI airport Domestic Terminal, Hauz Khas, IIT, Nehru Place, Jamia Milia University and NOIDA," DMRC Executive Director (Corporate Communications) Anuj Dayal said.
The tunnel which starts from Palam Metro station will emerge in the defence land at the end of the Dwarka flyover, Dhaula Kuan end, after covering a distance of 1.51 kms, from where the alignment will become elevated.
This particular tunneling drive is expected to be finished by December. The initial drive of the parallel tunnel is expected to start from May.
The 36.58 km long Janakpuri West Botanical Garden corridor of Phase 3 consists of 23.69 kms of underground lines.
Presently, six other tunnel boring machines (TBM) were working in different parts of the corridor across the city. In total, 20 TBMs are operational for the tunneling works of Phase 3 at present.
DMRC is slated to construct 53 km of underground Metro lines as part of its Phase 3 construction work for which about 34 TBMs are expected to be used. A total of 74 tunnels would be constructed in this phase.
