The Mumbai Mumbai Metro Rail Corporation (MMRC) achieved its final breakthrough at Mumbai Central station. This completes the tunnelling work of the Colaba-Bandra-Seepz underground Metro 3 corridor.

“It is with great pleasure that I witnessed the final breakthrough. It marks 100 per cent tunnelling of Metro-3 corridor. Tunnelling below Mumbai’s heritage precincts, in close proximity of old dilapidated buildings, existing Metro line, railway lines, water body with different and sometimes difficult geological conditions has been a daunting task,” said Ashwini Bhide, Managing Director, MMRC.

The section from Mahalaxmi Metro station to Mumbai Central station was the most challenging 837 metres of tunnelling. This includes Mumbai Central, Mahalaxmi, Science Museum, Acharya Atre Chowk and Worli Metro station which is one of the longest stretches of Metro line 3 corridors. Overall, the project has noted 76.6% progress.

“We used advanced technology without compromising the safety of workers. This was a daunting task for the MMRC team along with general consultants, contractors and jumbo vehicles,” S K Gupta, director (projects), MMRC, said.
