If I am not mistaken SWR's SBC division is good at this only. SWR is the worst zone of IR, but cleanliness and at construction RoBs, RuBs it is good at.
-
BYPL-SA route: I had travelled a few years ago, had noticed a lot of RuBs along the route.
YPR-TK route: Many RuBs built, many under progress.
YNK-BWT:...
more... After Devanahalli, there isn't one LC, I think.
YNK-DMM: Many flyovers on YNK-HUP highway under progress.
SBC-MYS: Few inside city limits built, few remain stuck due to encroachment and land acquisition problems.
