Of the 12 machines in Tamil Nadu, 10 will be manufactured in Chennai and two in Kancheepuram. After the remanufacturing process is complete, the company will have it certified for use from the original manufacturer after which it will be used here,” an official said, reports The Hindu.




I've no clue what the highlighted part means & I don't think it's a case of misprint or misreporting .

Ya'll Nibbiars assembly, there are still only two countries which can make the TBM from scratch that's the Germanu and the Mleecahs that's to the German help. What we do here is reassembly it's what I understand from the above quoted statements.

Ya'll Nibbiars Australia is Japanese owned, USA is also Chinese, may be Japanese and German owned operations only other independent is ROK. The turkey also a German collaboration. So yeah Four countries can manufacture all the TBM on it's own. We are still a new entry. The largest are Mleecahs, Germany, Japan and the ROK in that order.

Contractors are already installing the fibreglass roofs on coastal road tunnel entrance and progress is looking good. I think they'll open a partial section by May 2024.

Yes, I stand corrected. Daily commute people would rather enjoy this - INR 500 for a round trip /day * 25 working days = INR 12,500/- per month. Sounds like fun.
I am sure monthly passes will be a lot less. Plus I see travel commute mostly by high quality buses or carpools to work - not every individual driving to Mumbai. But even 250 rupees toll is high - almost amreeki toll rates. But the bridge was very expensive to build.
