Phase 2B Information

37 km Bangalore (Namma) Metro Phase 2B project envisions an airport-link from Bengaluru city to Kempegowda International Airport (KIAL) in Devanahalli through 17 stations.

A metro line to the airport has been on the drawing board since 2005 when construction commenced on the city’s airport. It was first envisioned as a high-speed rail link connecting the city’s CBD (MG Road) to be executed by a special purpose vehicle independent of the Bangalore Metro Rail Corporation.

In October 2015, RITES suggested 2 routes to the Bangalore Metro Rail Corporation (BMRCL). In September 2016, BMRCL sought suggestions from the public on 9 routes; they went on to finalize 4 routes in late-April 2017. In May 2017, they picked the route extending Line-4 via Nagawara, RK Hegde Nagar, Jakkur & Yelahanka. In January 2019, the Karnataka Government announced the approval of the line’s 37 km route with 17 stations as an extension of Line-5 (ORR Line) via KR Puram, Nagawara, Hebbal & Yelahanka.

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.

In April 2021, Phase 2B was approved by the Central Government’s cabinet. BMRCL has not published Phase 2B’s DPR (Detailed Project Report) online.
