DMRC milestone: First-ever tunnelling stretch of Ph-IV project completed

In a major milestone for the Delhi Metro, the urban transporter on Friday achieved the completion of its first-ever tunnelling stretch under Phase-IV project of its network, officials said.

This was achieved at Krishna Park Extension on the Janakpuri WestR K Ashram Marg corridor with a tunnel boring machine (TBM) breaking through after boring a 1.4 km-long tunnel, they said.

The work on Phase-IV had begun in December 2019 with a groundbreaking ceremony but it was hit after the outbreak of COVID-19 in March 2020.

The lowering of the first-ever TBM under the Phase-IV project had started at Vikaspuri on the Janakpuri WestR K Ashram Marg corridor in October 2020, and following the initial drive, the main tunnelling had started early 2021, officials said.
