Chief PRO of BMRCL, BL Yashwanth Chavan, informed that the suburban rail will run below the Namma Metro viaduct for a length of 500m adjacent to Benniganahalli flyover. While the KR Puram-KIA airport Metro corridor’s rail-level height will be 18-20m above ground, suburban rail will be around 12m. But there will be no double-decker structure as each one will be independent. Before this, K-RIDE had proposed to create a double-decker line at Benniganahalli for a 3km stretch and the length alone was expected to save the government about ₹300 crore in land acquisition cost as Metro pillars and land could be used to build the suburban rail corridor.
