Godavari-4 was commissioned on August 21, 2019, from BKC launching shaft and shaped the tunnel with 1,043 RCC rings up to Dharavi. This is the 29th breakthrough on the Colaba-Bandra-SEEPZ Metro-3 corridor.
"Notwithstanding the fact that the project is challenging; with high water tables and complex geology, I am happy that our team has accomplished the assigned task despite COVID-19 related restrictions," said Ranjit Singh Deol, MMRC managing director, in a press release.
It may be noted that earlier in March this year before the outbreak of the COVID-19 pandemic, the Godavari-3 had completed the downline tunnel of 1.5-km from BKC to Dharavi. Out of the total 3-km (up and downline) stretch from BKC to Dharavi, a 484-meter tunnel lies below the active Mithi river channel.
