CM Shivakumar unveiled a long-term vision to expand Namma Metro to 500 km, with 175 km operational by December 2027 — backed by a Rs 1.5 lakh crore urban development budget.
Bengaluru's metro network could grow more than fivefold under a sweeping expansion masterplan announced by Karnataka Chief Minister D.K. Shivakumar at the KATALYST CONNECT summit on 8 July 2026. The plan envisions a 500 km metro network across the city, transforming Namma Metro from its current 96 km footprint into one of India's largest urban rail systems.
175 km by December 2027
The immediate milestone is bringing the operational network to 175 km by December 2027. This includes completing the remaining stretches of the Purple Line extension to Whitefield and Challaghatta, the Green Line extension to Madavara, and the Yellow Line corridor from RV Road to Bommasandra — all of which are in advanced stages of construction or testing.
The Pink Line, Bengaluru's first underground metro corridor, is also expected to open in phases through 2027, adding another key north-south artery to the network.
Rs 1.5 Lakh Crore Urban Push
The 500 km vision is part of a broader Rs 1.5 lakh crore urban development budget aimed at positioning Bengaluru as a global technology and business hub. Shivakumar tied the metro expansion directly to the state's goal of attracting 500 new Global Capability Centres (GCCs) and creating 3.5 lakh jobs by 2029.
Better metro connectivity is seen as critical for reducing commute times and easing the city's chronic traffic congestion — a frequent complaint from both residents and companies considering setting up operations in Bengaluru.
What 500 km Would Look Like
For context, only Delhi Metro currently exceeds 400 km of operational lines in India. A 500 km Namma Metro would place Bengaluru among the world's largest metro networks by route length.
The expansion would likely include corridors identified in earlier feasibility studies — connecting areas like Hebbal, Sarjapur, Hosur Road, and the airport — though specific route alignments for the new corridors have not been finalised.
What This Means for Commuters
- The current 96 km network serves roughly 7–8 lakh passengers daily.
- 175 km by end-2027 would nearly double coverage and add interchange options across the Purple, Green, Yellow, and Pink lines.
- The long-term 500 km target signals sustained investment, though timelines for corridors beyond the current Phase 2 and 3 projects remain uncertain.
- BMRCL is conducting feasibility studies to add 200 km of new corridors, a process that typically takes 2–3 years before construction begins.
The announcement marks a significant shift in ambition from earlier plans, which focused on completing the existing 175 km network. Whether the 500 km vision can be delivered on schedule will depend on land acquisition, funding approvals, and execution speed — areas where Bengaluru's metro projects have historically faced delays.
