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. By February 2018, BMRCL had only signed only 2 MoUs worth approximately Rs 100 crore each.

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. Technical bids were opened in March 2020 to reveal 9 bidders, and financial bids were opened in October to reveal Afcons Infrastructure and Shankarnarayana Construction as the lowest bidders. Construction contracts were awarded in May 2021.

  • BMRCL’s Current Phase 2A Deadline: June 2025
  • My Completion Estimate: 2027

In April 2021, Phase 2A was approved by the Central Government’s cabinet.

Phase 2A and Phase 2B (KR Puram – Yelahanka – Bangalore Airport) will be funded through a $500 million loan by the Asian Development Bank (ADB) which was approved by its board in December 2020. In addition, Japan International Cooperation Agency (JICA) will provide a $318 million loan as well. A formal agreement for it was signed in March 2021.

Phase 2A’s Funding

Estimated Cost: Rs. 5,227.35 crore

  • ADB: Rs. 1,479.46 crore
  • JICA: Rs. 893 crore (preliminary negotiation)
  • PPP Sources: Rs. 600 crore
  • State Govt: Rs. 1,690.46 crore
  • Central Govt: Rs. 734.22 crore
