The most ambitious line of the Mumbai Metro, Line 3, will connect Colaba to Seepz in Andheri East.
If you’re a citizen of Mumbai, you’ve probably seen some line of the city’s Metro project being constructed. Currently, 4 lines of the Mumbai Metro are under construction, but perhaps the most ambitious line of the metro is Line 3, which will be completely underground. Starting at South Mumbai’s Colaba, passing through the business district of Bandra Kurla Complex and ending at Andheri’s Seepz with a car-shed at Aarey Colony in Goregaon, the project will be commissioned by the end of 2021. But how exactly is this metro being constructed underground? CNBC-TV18’s Kevin Lee went to the project’s CST site, 25 metres underground, to find out.
