Bengaluru: 170-Km Of Tunnels, Flyovers Proposed

As per the pre-feasibility report, the travel time on the north-south tunnel corridor from Hebbal to Silk Board Junction is expected to be reduced from 90 minutes to just 20 minutes. The Bruhat Bengaluru Mahanagara Palike (BBMP) published the final feasibility report on the Comprehensive Bengaluru City Traffic Management Infrastructure Plan prepared by Altinok Consulting Engineering. The report consists of a detailed feasibility study on the proposed 170-km network of tunnels, double-decker passageways, elevated corridors and underpasses to streamline mobility and decongest Bengaluru traffic. The study proposes traffic management and road infrastructure solutions in terms of vehicular tunnels, grade separators, and road widening in selected corridors. As part of the plan, 16 elevated corridors and two tunnels have been proposed. The total length of elevated corridors/ double deckers/ underpasses amounts to 124.7 km. Meanwhile, the total length of tunnels (north-south and east-west) amounts to 46 km. Some of the important elevated corridors include Yeshwanthpura-KR Puram (27 km), Shoolay Circle to Madiwala junction (7.4 km), Marenahalli main road to Thalaghatapura NICE Road (10.5 km), Swami Vivekananda Metro Station-Madiwala (10 km), proposed additional link road to Kempegowda International Airport (KIA), elevated corridor from Outer Ring Road-Hennur Main Road to Bagalur junction (15 km) and Nagawara-Bagalur main road (15 km). Meanwhile, the proposed double-decker corridor with Phase 3 Metro line connects Hosahalli to Kadabagere (13 km), and a double-decker corridor connects BEL Road and Yeshwanthpur Railway station (2.2 km). Further, a tunnel road of 18 km is proposed from Hebbal to Silk Board (north-south) and KR Puram to Nayandahalli (east-west, 28 km). As per the pre-feasibility report, the travel time on the north-south tunnel corridor from Hebbal to Silk Board Junction is expected to be reduced from 90 minutes to just 20 minutes. The report also indicates that the north-south tunnel corridor faces infringement with the proposed alignment of the Bengaluru Metro Rail Corporation Limited (BMRCL) in nine places, besides infringement with the Bengaluru Suburban Rail Project in two places. The total cost estimated is around Rs 150 billion.
