Delhi Metro completes work on longest tunnel

NEW DELHI: The Delhi Metro achieved another feat by completing the construction work of its longest ever underground tunnel at Khan Market.

The tunnel, with a length of 1.775 kilometres, is part of the under construction corridor between Central Secretariat and Badarpur and is the longest ever constructed by single tunnel boring machine (TBM) in Delhi Metro, DMRC spokesman Anuj Dayal said.

Till now, two 1.45 kilometre long tunnels constructed between Malviya Nagar and Hauz Khas were the longest tunnels.

Another major achievement is that the construction was completed in just 152 days.

Dayal said of the 1.775 kms, 37.5 metres of tunneling was completed in a day with the installation of 25 rings which is an Asian record.

The tunneling work for this stretch was started on November 21st, 2008. The Central Secretariat — Khan Market stretch of 2.53 kilometres is actually the longest distance between any two Metro stations under Delhi Metro.
