Decongesting Bengaluru: Namma Metro, Blue & Pink Line, To Flyovers & Airport, Projects In The Works

Bengaluru is set for an infrastructure makeover with focus on mass transit expansion, congestion reduction, and climate resilience.
The key aim is mass transit expansion, with metro and suburban rail projects intended to move a significant share of daily commuters off private vehicles. If executed as planned, these projects will fundamentally change how people travel across longer distances within the city and between the city and its suburbs.
While some projects will deliver benefits by 2026–2027, the biggest transformations (Phase 3 Metro, PRR, tunnel roads) will shape the city closer to 2030 and beyond.

The key projects you should know about: Namma Metro – Phase 3: Namma Metro Phase 3 is the next large expansion of Bengaluru’s metro network,

aimed at connecting outer suburbs and fast-growing corridors that are currently road-dependent. The phase covers roughly 105 km of new metro lines, including corridors such as Sarjapur-Hebbal and Magadi Road-Kadabagere. Status: Approved; detailed project reports and land acquisition are in progress. Expected completion: Phased commissioning between 2028 and 2032, depending on corridor.

Metro Blue Line (KR Puram–Kempegowda International Airport): This is the dedicated airport metro line connecting central and eastern Bengaluru to Kempegowda International Airport. It is critical for reducing road congestion on Bellary Road and providing reliable airport access.
Status: Under active construction with elevated viaducts and stations taking shape.
Expected completion: Late 2026 to early 2027 (phased openinort possible).

Metro Pink Line (Kalena Agrahara-Nagawara): The Pink Line is a north–south metro corridor with significant underground sections through the city core. It connects South Bengaluru to Nagawara via central business districts.
Status: Civil construction largely completed in sections; systems installation and testing underway.
Expected completion: 2026 (partial opening may occur earlier).

Bengaluru Suburban Rail Project (BSRP): The Suburban Rail Project is a city-scale commuter rail system designed to connect Bengaluru with its suburbs such as Tumakuru, Ramanagara, Hosur, and Devanahalli. It spans 148 km across four corridors with 58 stations.
Status: Construction has begun on priority corridors; land acquisition and utility shifting ongoing.
Expected completion: Initial corridors by 2027–2028, full network by 2030.

Bengaluru Business Corridor (Peripheral Ring Road – PRR): Formerly called the Peripheral Ring Road, this 73 km expressway will act as an outer bypass for freight and long-distance traffic, reducing pressure on the Outer Ring Road and city roads.
Status: Land acquisition is underway with phased execution planned.
Expected completion: 2028–2030, depending on acquisition progress.

Tunnel Road Project: The Tunnel Road Project proposes underground road tunnels running east–west and north–south beneath the city to bypass surface congestion in central Bengaluru. These tunnels are intended mainly for through traffic.
Status: Feasibility studies and detailed project reports under preparation; not yet under construction.
Expected completion: If approved, construction could begin around 2026, with completion around 2032.

Double-Decker Flyover Corridors: These projects involve building two-level corridors where metro lines run above elevated roads, particularly along heavily congested stretches like Silk Board–KR Puram.
Status: Planning and early execution stages; coordination with metro construction ongoing.
Expected completion: 2027–2029, corridor-wise.

Kempegowda International Airport – Terminal 2 Expansion & Airside Works: Following the opening of Terminal 2, further expansion of terminal facilities, taxiways, and cargo infrastructure is underway to handle increasing passenger and freight demand.
Status: Ongoing phased expansion by BIAL.
Expected completion: Continuous expansion through 2027-2030.

Proposed Second Bengaluru Airport (South Bengaluru): The Karnataka government has proposed a second international airport to serve South Bengaluru in the long term, as Kempegowda Airport approaches saturation.
Status: Site feasibility studies and policy discussions underway; no final site approved yet.
Expected completion: Not before mid-2030s, if approved.

Stormwater Drain (SWD) Revamp & Flood Mitigation Project: This project involves widening, rebuilding, and interlinking Bengaluru’s stormwater drains to prevent flooding in low-lying and IT corridor areas such as Mahadevapura, Bellandur, and Outer Ring Road.
Status: Actively under execution in multiple packages.
Expected completion: Major stretches by 2026, with continuous upgrades beyond.

Bellandur-Varthur Lake Rejuvenation Project: This large environmental infrastructure project focuses on lake desilting, sewage diversion, and flood control to address chronic flooding and pollution in East Bengaluru.
Status: Multi-agency execution in phases.
Expected completion: 2026-2027 for core works.

Integrated Mobility Hubs (Majestic, KR Puram, Yeshwantpur): These hubs are designed to integrate metro, suburban rail, buses, parking, and pedestrian access at major interchange points to improve public transport efficiency.
Status: Planning and phased construction underway.
Expected completion: 2026-2028, hub-wise.

Bengaluru Smart City & Intelligent Traffic Systems (Phase 2): This includes smart signals, adaptive traffic control, surveillance, command centres, and digital urban infrastructure upgrades across the city.
Status: Ongoing rollout and upgrades.
Expected completion: Continuous implementation through 2026.
