Chief minister Devendra Fadnavis on Thursday gave his nod to commence paperwork, including inviting tenders and having financial tie-ups, for three crucial projects of Mumbai.

Which are the projects?The projects — Dahisar-Charkop-Bandra-Mankhurd (DCBM) metro line, Wadala-Ghatkopar-Thane (Teen Haath Naka)-Kasarvadavali (WGTK) metro route, and flyovers on Kalanagar junction — have been at the planning stage for years now.

On Thursday, dna had reported about how Fadnavis, who is also the chairman of Mumbai Metropolitan Region Development Authority (MMRDA), will have to take a call on these important infrastructure projects that will transform the way citizens travel.

What do the metro projects involve?As per the plans approved by Fadnavis, the much-needed-and-delayed DCBM corridor will be 40km-long having 36 underground stations. It will be implemented at an estimated cost of Rs25,605 crore.

WGTK metro will have six elevated stations on Ghodbundar Road, the remaining will be 24 underground stations along the overall 32km-long route. Estimated cost of this project is Rs19,097 crore.

Who will fund them?“Both corridors will be implemented by the Mumbai Metro Rail Corporation within six to seven years. These metro lines will be funded by raising loan to the tune of 50% of the cost from international finance agencies, while central government and state government are likely to provide 20% and 30%, respectively, by way of equity and sub debt,” said Dilip Kawathkar, spokesperson for MMRDA.

Why are flyovers needed at Kalanagar Jn?At an estimated cost of Rs227 crore, a maze of flyovers and a road will be built at Kalanagar Junction in Bandra (East). “The aim is to clear the daily rush-hour traffic chaos in Bandra-Kurla Complex. A survey conducted has revealed that every hour an average of over 12,000 cars crowd the junction. This problem will be solved by constructing four flyovers and a road,” added Kawathkar.

Which areas will they connect?There will be a flyover each to reach the Bandra-Worli Sea Link from BKC and the other way around. The total length of these two two-lane flyovers will be 1,888 metres. The flyover connecting Dharavi to Western Express Highway (WEH) will join the flyover from BKC at the second level and there will be a three-lane flyover connecting the one reaching WEH. This flyover will be 2,920m-long.

MMRDA also sanctioned construction of a 300m-long and 12ft-wide road running through government land to streamline traffic from Dharavi to sea link.
