BENGALURU: If all goes well, Silk Board junction is likely to become traffic free in three to four years. On Friday, BBMP and BMRCL mutually agreed to share cost to build an integrated flyover and metro track from Ragigudda temple in Jayanagar 9th block to Silk Board junction. The total project costs Rs 800 crore and BMRCL has already awarded the contract for the work to hit the ground soon.The flyover was announced in the state budget of 2016-17. It will be a four lane road covering roughly 4 km between the two points on the ring road in south Bengaluru and is estimated to be worth Rs 330 crores. N Manjunath Prasad, BBMP Commissioner said, “Out of the total cost for building the elevated road, BBMP has agreed to pay Rs 100 crores to BMRCL and the latter will execute the entire project.”But the old flyover at Silk Board and Jayadeva hospital junction will not be demolished. The new elevated road will serve as a deck for the upcoming interchange stations at both these traffic junctions like a 'road cum rail’ flyover.“The work has already been awarded for the RV Road—Silk Board part of the 19 km route and work will have to be complete in 27 months. The total cost of the road cum rail flyover will be Rs800 crores,” said Pradeep Singh Kharola, MD-BMRCL. Two other packages have already been awarded on the RV road—Bommasandra line—19 km, between Silk Board and Hosa road and from Electronic City-1 to Bommasandra to expedite the project and complete by 2020 deadline.The 17-km Outer Ring Road (ORR) metro line proposed to be an extended part of the second phase of metro project, connects Silk Board junction with KR Puram and RV Road-Bommasandra line. There will be two tracks one each towards Electronic City and KR Puram and have one station each to serve towards the different corridors. This has lessened the land acquisition at Silk Board—two acres.
