The construction for the prestigious Metro-3 project is being done by the Mumbai Metro Rail Corporation (MMRCL) at a commendable speed. The project will bring the first underground transport route to Mumbai in form of the Colaba-Bandra-SEEPZ route. Under the 38.28 km long underground route, a 915-meter route will be constructed under Mumbai's very Mithi river.

MMRC is constructing three tunnels under Mithi, out of which, two of the tunnels are 1.5 km long each whereas the remaining tunnel is a 154-meter long route. As of now, the construction of 660 meters for the first tunnel, 240 meters for the second one, and 15 meters for third is finished.

The 1.4 km long Metro-3 route between Dharavi and BKC will be connected via the tunnel under Mithi river. Meanwhile, according to the reports it is being said that the construction will be completed by January 2020. The entire underground route will be built 25 meters below Mithi. 

Meanwhile, the two 1.5 km long tunnels will function as main lines whereas the 154-meter long route will be used as a stabling line. The stabling line will be used for the trains that are cancelled from BKC and will return back to the station.

On the other hand, MMRC had recently announced that it had completed 70 per cent of the tunnelling work that was required for Colaba-Bandra-SEEPZ Metro-3 corridor. The Colaba-Bandra-SEEPZ Metro-3 corridor is the first and only fully underground corridor for Mumbai.

Praising the employees, MMRCL Managing Director, Ashwini Bhide had said that she was proud of the Metro-3 team who achieved the challenge in just two years. She also added that the 'gigantic engineering marvel' has been created with the help of a team of 16,000 people working day and night.

Currently, the Tunnel Boring Machine (TBM) has completed digging 900 meters of underground tunnels, thus finishing 1/3rd of the designed route.
