So finally namma metro has rolled out and is being functional. After many delays. It looked nice in the photos. And hope it'll be maintained as such, even in the future. And also, hope that the rest of it is delivered to the public within the scheduled time.
But, yes, there was (and is?) a lot of damage caused to the roads when the lines were (and are) being laid. Wish the roads are made usable again (not that they are not in use).
