Phase 2A Information

Bangalore (Namma) Metro’s Phase 2A project with one new 18.236 km elevated line, connecting KR Puram with Central Silkboard along the Outer Ring Road (ORR), was first announced at the Invest Karnataka Summit in February 2016 and is planned to be constructed along with the 73.92 km Phase 2 project.

Bangalore Metro Rail Corporation Ltd. invited bids for geotechnical investigation and DGPS, topographic, land & property surveys in June 2016. The line’s Detailed Project Report (DPR), prepared by BMRCL’s in-house team, was revealed in November 2016 and estimates the line’s construction & system procurement to cost Rs 4202 crores.

The Karnataka government’s cabinet approved the project’s DPR in March 2017. Back then, instead of relying on foreign lenders, the BMRCL had planned to fund this line through what it called an “innovative financing model” in which private entities would have been engaged to pitch in anywhere from 25% to 50% of the line’s construction cost (Rs. 1100-2100 crores) and in return be granted exclusive advertising and leasing rights within the stations to monetize on their investment. As of August 2017, the BMRCL had only signed 1 MoU worth Rs 100 crore.

In 2018-2019, the BMRCL invited bids for the line’s construction in 3 packages. During that time, BMRCL was unable to achieve financial closure and the lowest bidder for all 3 packages, IL&FS Engineering and Construction Company Limited, was hit by financial troubles.

In December 2019, BMRCL re-invited tenders for its construction and bids were opened in March 2020 to reveal 9 bidders. The line is now planned to be funded through an official development assistance (ODA) loan by the Asian Development Bank (ADB) which also plans to finance the line’s 37 km extension to the Bangalore Airport (KIAL) in Devanahalli through Hebbal and Yelahanka as part of Phase 2B.
