On Monday, November 17, 2025, the Karnataka government officially gave the green signal for the Bengaluru–Tumakuru Metro extension, marking the first time Namma Metro will connect beyond Bengaluru city limits.
In a landmark decision, the Karnataka government has cleared the much-anticipated 59.6 km extension of Namma Metro’s Green Line from Madavara (BIEC) to Tumakuru. This move paves the way for inter-district metro connectivity for the first time in Karnataka, promising to reshape travel between Bengaluru and Tumakuru.
Route Map – Silk institute to Kyathsandra [ Tumakuru ] :
-
Route: The corridor will run through Nelamangala, Dabaspet, and Kyathasandra, before terminating at Tumakuru.
-
Stations: Around 25–27 stations are planned along the alignment.
-
Cost: The project is estimated at ₹20,600 crore, proposed under a Public-Private Partnership (PPP) model.
-
Next Steps: Bangalore Metro Rail Corporation Limited (BMRCL) has floated tenders for a Detailed Project Report (DPR), with bids opening on November 21, 2025.
Public and Political Regions :
While the announcement has been welcomed by many commuters and urban planners, it has also sparked debate:
-
Supporters argue the extension will ease congestion on highways, reduce travel time, and boost Tumakuru’s economic integration with Bengaluru.
-
Critics, including BJP MP Tejasvi Surya, have raised concerns, calling the project a “scheme that primarily benefits real estate interests.” He urged the government to consider lower-cost alternatives such as suburban rail or a Regional Rapid Transit System (RRTS).
Broader impact on Public :
-
Regional Development: The Metro extension is expected to stimulate growth corridors along NH-48, attract investment, and improve accessibility for Tumakuru residents.
-
Environmental Benefits: Metro connectivity offers a low-emission alternative to road travel, potentially reducing vehicular pollution.
-
Debate on Suitability: Transport activists caution that Metro systems are designed for intra-city travel, and suburban rail might be more efficient for long-distance commuters.
The government’s green signal on Monday marks a turning point in Karnataka’s transit planning. If executed, the Bengaluru–Tumakuru Metro will not only be a game-changer for commuters but also a symbol of inter-district integration. However, the coming months will reveal whether the project can balance cost, feasibility, and commuter needs.
