BENGALURU, August 10, 2025 — Prime Minister Narendra Modi today laid the foundation stone for Bangalore Metro Phase 3, marking a major step in the city’s mass transit expansion. The project, with a sanctioned cost of ₹15,611 crore, will add 44.65 km of new lines, strengthening connectivity across Bengaluru’s western and southern corridors.

Phase 3 will include a 32.15 km stretch from JP Nagar 4th Phase to Kempapura along the Outer Ring Road West, and a 12.5 km stretch from Hosahalli to Kadabagere along Magadi Road.

“Since 2014, the Union Government has released ₹27,209 crore for various Bangalore Metro projects, including ₹2,217 crore allocated in the current fiscal year. Of this, ₹544 crore has already been disbursed, with no pending funding requests from the Bangalore Metro Rail Corporation Limited (BMRCL),” said a note shared by the Central government.

Progress on Ongoing Phases

Phase 1: Fully operational since completion of its 42.30 km network at a cost of ₹14,133.17 crore.
Phase 2: ₹26,405.14 crore project spanning 72.095 km (53.8 km already operational). Key stretches like the Yellow Line (R.V. Road–Bommasandra) were commissioned this month, with underground works on Reach-6 expected to complete by September 2026. Physical progress stands at 94.5% and financial progress at 91.66%.
Phase 2A & 2B: Covering 58.19 km from Central Silk Board to the airport via Hebbal, the project has achieved 52.5% physical and 55.89% financial progress as of June 30, 2025.

Future Plans and Requests to State Government

BMRCL has prepared the DPR for Phase 3A — a 36.58 km Sarjapura–Hebbal corridor with an estimated cost of ₹28,405 crore. The Ministry of Housing and Urban Affairs (MoHUA) has returned the DPR to the Karnataka government for cost review under its benchmarking guidelines. The Centre has urged the state to expedite the process and draft a long-term master plan for future corridors to address Bengaluru’s traffic congestion.

With Phase 3’s foundation now laid, Bengaluru’s metro map is set to expand significantly in the coming years, promising smoother commutes and reduced vehicular pressure on city roads.

Speaking on the occasion, the Prime Minister said: “We are seeing Bengaluru emerge as a city that has become a symbol of New India’s rise — a city whose soul holds the wisdom of philosophy, and whose actions embody the knowledge of technology. A city that has hoisted India’s flag high on the global IT map.’

He also stated that “urban planning and urban infrastructure in the 21st century are among the greatest needs of our cities. We must prepare cities like Bengaluru for the future as well.”
