Bangalore infrastructure and what it does to property markets

Bangalore Metro Phase 3A

Status: Planned

Phase 3A is a proposed metro corridor of roughly 37 km linking Sarjapur to Hebbal through Agara, Koramangala and the central area. It has state-level approval in principle but no committed construction timeline, so treat it as planning-stage upside rather than a delivered asset.

Bangalore Metro Phase 2B

Status: Under construction

Phase 2B extends the Blue Line about 38.4 km from KR Puram to Kempegowda International Airport with around 17 stations, via Hebbal, Jakkur, Yelahanka and Bagalur Cross. It is the first rail link to the airport terminal and the most consequential single project for North Bengaluru property.

Bangalore Metro Phase 2A

Status: Under construction

Phase 2A is a 19.75 km elevated Blue Line corridor with 13 stations along the eastern Outer Ring Road from Central Silk Board to KR Puram. It puts Bellandur, Kadubeesanahalli, Marathahalli and Doddanekkundi on the metro map and interchanges with the Yellow Line at Silk Board and the Purple Line at KR Puram.

Bangalore Metro Expansion

Status: Under construction

Namma Metro currently runs the Purple and Green lines plus the Yellow Line to Bommasandra, roughly 96 km in service. Three more packages are under construction: Phase 2A along the eastern Outer Ring Road, Phase 2B to Kempegowda International Airport, and Phase 3 in the west. BMRCL is the implementing authority, and the airport link is the single change most likely to reset North Bengaluru prices.

Bangalore Metro Phase 3

Status: Approved — pre-construction and tendering

Bangalore Metro Phase 3 is an approved 44.65 km, two-corridor elevated expansion of Namma Metro covering the western Outer Ring Road (JP Nagar 4th Phase to Kempapura) and Magadi Road (Hosahalli to Kadabagere), with 31 stations planned. It is in the pre-construction and tendering stage under BMRCL, not under passenger operation, and the areas most directly affected are west and north-west Bengaluru.

Bangalore Metro Phase 2

Status: Largely operational; balance sections under construction

Namma Metro Phase 2 is the roughly 75 km expansion of Bengaluru''s metro network built by BMRCL. It extends the Purple and Green lines to Whitefield, Challaghatta, Madavara and Silk Institute, and adds the new Yellow Line between RV Road and Bommasandra along Hosur Road. Most of Phase 2 is operational; remaining sections are under construction.

Outer Ring Road (ORR) Infrastructure

Status: Operational with upgrades

The Outer Ring Road is a roughly 60 km ring around central Bengaluru that hosts the city's largest office cluster between Silk Board and Hebbal. Its main upgrades are Metro Phase 2A and 2B above the eastern and northern stretches, the Phase 3 Orange Line on the western side, and ongoing junction and service-road improvements.

Satellite Town Ring Road (STRR)

Status: Under construction

The Satellite Town Ring Road is a roughly 280 km national highway ring (NH-948A) being built by NHAI around Bengaluru, linking satellite towns such as Dobbaspet, Doddaballapur, Devanahalli, Hoskote, Anekal, Kanakapura and Ramanagara. It lets freight bypass the city and opens these towns to logistics and industrial growth.

Hosur Road Development

Status: Highway and elevated expressway operational; Yellow Line metro operational

Hosur Road (NH-44) is Bengaluru''s southern corridor, served by the Electronic City elevated expressway, the six-lane national highway towards Hosur, and since 2025 the Namma Metro Yellow Line between RV Road and Bommasandra. It links Silk Board, Bommanahalli, Kudlu, Electronic City and Bommasandra to central Bengaluru.

Bangalore Peripheral Ring Road (PRR)

Status: Proposed / land acquisition stage — not under construction

The Peripheral Ring Road, now developed as the Bengaluru Business Corridor, is a proposed roughly 73 km eight-lane ring road planned by the BDA between Tumkur Road and Hosur Road via Hebbal, Bagalur, Whitefield and Sarjapur Road. It is at the land acquisition and tendering stage, not under construction, so its benefits remain expected rather than confirmed.

Devanahalli Infrastructure

Status: Airport and industrial parks operational; metro under construction

Devanahalli, about 35–40 km north of central Bengaluru, is anchored by Kempegowda International Airport. Its infrastructure base includes the six-lane NH-44 highway, the Satellite Town Ring Road, the KIADB Aerospace Park and Hardware Park, Airport City developments, and the under-construction Blue Line metro to the airport terminal.

Bangalore Airport Connectivity

Status: Road link operational; metro under construction; suburban rail planned

Kempegowda International Airport is reached today by the Bellary Road (NH-44) six-lane highway with a dedicated trumpet interchange, plus BMTC Vayu Vajra buses. Rail access is being built: the Blue Line metro from Central Silk Board and KR Puram to the airport is under construction, and a suburban rail corridor to Devanahalli is planned by K-RIDE.

Bengaluru Suburban Rail

Status: Under construction (Corridors 2 and 4 prioritised)

The Bengaluru Suburban Rail Project is a roughly 148 km, four-corridor commuter rail network being implemented by K-RIDE, with 57 stations planned. Corridor-2 (Mallige, Benniganahalli–Chikkabanavara) and Corridor-4 (Kanaka, Heelalige–Rajanukunte) are being built first. Construction is underway; no corridor is fully operational yet.

Bangalore Rajakaluve Map: Property and Flood-Risk Guide

A Bangalore rajakaluve map helps buyers identify major drainage channels near a property, but it cannot establish flood safety or legal clearance on its own. Drain upgrades can improve liveability; their property benefit depends on downstream capacity, maintenance, site elevation and the building’s own drainage.

Cauvery Stage 5: Bangalore Water Supply and Property

Cauvery Stage 5 expands Bengaluru’s water supply, with particular relevance to peripheral neighbourhoods. For homebuyers, the benefit depends on an active connection and dependable delivery—not a nearby pipeline. Verify the building’s BWSSB bills, supply records and remaining tanker costs before paying a premium.

West Bangalore Development

Status: Developing

West Bangalore — Rajajinagar, Yeshwanthpur, Peenya, Vijayanagar, Mysore Road, Kengeri and Magadi Road — is served by the Purple Line to Challaghatta, the Green Line through Peenya, the Bengaluru–Mysuru expressway and the Phase 3 Orange Line under construction. It offers some of the city's best value for metro-connected housing.

South Bangalore Development

Status: Developing

South Bangalore — Jayanagar, JP Nagar, Bannerghatta Road, Kanakapura Road and Hosur Road — is served by the Green Line metro to Silk Institute, the Yellow Line to Bommasandra, NICE Road and the planned Phase 3 Orange Line on the western ORR. It combines mature neighbourhoods with steady growth corridors along Kanakapura and Bannerghatta roads.

East Bangalore Development

Status: Developing

East Bangalore — Whitefield, Marathahalli, KR Puram, Varthur and Sarjapur Road edge — is driven by the ITPL and ORR tech belts, the operational Purple Line to Whitefield, Metro Phase 2A along the ORR and suburban rail stations at Whitefield. It is the city's deepest rental market, with prices supported by real jobs rather than plans.

North Bangalore Development

Status: Developing

North Bangalore's growth is driven by Kempegowda International Airport, the airport metro (Phase 2B), suburban rail, the STRR, and business parks along Bellary Road. Hebbal, Yelahanka, Jakkur, Thanisandra, Bagalur and Devanahalli are the main residential markets, with prices rising steadily on real infrastructure rather than announcements alone.

Electronic City Infrastructure

Status: Operational with upgrades

Electronic City now has three pieces of major infrastructure: the 9.9 km Hosur Road elevated expressway, the Yellow Line metro from RV Road to Bommasandra, and proximity to the planned suburban rail Kanaka corridor terminus at Heelalige. Together they have turned it from a traffic-bound tech park into a well-connected residential market.
