Bangalore (Metro Rail News): The Bangalore Metro Rail Corporation Limited (BMRCL) is set to commence the geotechnical investigation for the expansion of the Bangalore Metro system under its Phase III project. This new phase aims to add 44.65 km of metro lines across the city, encompassing two elevated corridors and 31 metro stations in total.
Phase III of the metro expansion includes two main corridors:
- Western Corridor: Spanning 32.15 km from J P Nagar’s fourth phase to Kempapura, this corridor will connect 22 stations and link directly to the Airport Line.
- Eastern Corridor: This segment will have nine stations and cover 12.5 km from Hosahalli to Kadabgere on Magadi Road.
The Karnataka government approved the Phase III expansion earlier this year, with plans to integrate the new lines into the existing network by 2028. The project, estimated to cost Rs 15,611 crore, will be primarily funded by the state government, covering 80-85% of the total cost. The remainder will be financed by the central government, which has already approved the project and finalised the Detailed Project Report (DPR).
Geotechnical Investigation
The geotechnical investigation, which has a budget of Rs 6 crore, is scheduled to start next week. Officials from BMRCL highlighted that the investigation will focus on examining the physical properties of soil and rock along the proposed routes. This process is essential for determining the depth and design of the foundations needed for metro pillars.
Current Metro Network
Bangalore’s metro, currently the second longest operational network in India, spanning 73.81 kilometres after Delhi, consists of two operational corridors:
- East-West Corridor: Runs 43.49 km from Whitefield Station east to Challagatta Terminal west.
- North-South Corridor: Extends 30.32 km from Nagasandra Station north to Silk Institute Station south.
With the initiation of Phase III, Bangalore is poised to significantly enhance its metro connectivity, further easing the city’s transportation woes and contributing to its urban development.
