Bangalore Metro Phase 2A & 2B Route Map, Stations & Status

Bengaluru’s metro network has steadily evolved into a critical layer of the city’s urban infrastructure. As road congestion intensifies and employment corridors expand outward, public transit is no longer just a mobility solution but a planning necessity. The next phase of this transformation lies in Bangalore Metro Phase 2A and Phase 2B, two corridors designed to strengthen east–north connectivity. 

This blog explains what Bangalore Metro insights of Phase 2A and 2B are, how the routes are aligned, which stations are part of each phase, the current construction status, and why these corridors matter for the city’s long-term growth and accessibility. 

Introduction to Bangalore Metro Phase 2A & 2B 

Bangalore Metro Phase 2A and Phase 2B together form a continuous transit corridor linking the Outer Ring Road (ORR) tech belt to the northern parts of the city and the airport region. Conceptually planned as an extension of the Blue Line, these phases address two long-standing gaps: poor public transport along ORR and limited metro access to North Bengaluru. 

While Phase 2A focuses on the ORR stretch between Silk Board and KR Puram, Phase 2B extends the line further north towards Kempegowda International Airport. Both phases are elevated corridors and are being implemented by Bangalore Metro Rail Corporation Limited (BMRCL). 

What is Bangalore Metro Phase 2A? 

Bangalore Metro Phase 2A is an elevated metro corridor running along the Outer Ring Road from Silk Board Junction to KR Puram. This stretch is one of the city’s busiest employment corridors, hosting major IT parks, office campuses, and high-density residential developments. 

The primary objective of Phase 2A is to provide reliable mass transit along ORR, a corridor that currently depends heavily on private vehicles and buses. By running parallel to ORR, Phase 2A is expected to reduce surface traffic congestion and significantly cut travel time between South-East and East Bengaluru. The corridor also integrates with existing and upcoming metro lines, strengthening network connectivity rather than functioning as a standalone route. 

What is Bangalore Metro Phase 2B? 

Bangalore Metro Phase 2B is the northern extension of the same Blue Line corridor, starting from KR Puram and moving towards Kempegowda International Airport. This phase connects East Bengaluru to North Bengaluru and the airport zone through a predominantly elevated alignment. 

Phase 2B addresses a critical mobility gap: the absence of direct, high-capacity rail transit between the city’s eastern IT districts and the airport. Once operational, it is expected to reduce dependence on road-based airport transport and improve access to emerging residential and commercial zones in North Bengaluru. The corridor also links with existing metro lines at key interchange stations, enabling cross-city travel without multiple road transfers.

Bangalore Metro Phase 2A & 2B Route Map 

Together, Phase 2A and Phase 2B form a continuous metro alignment from Silk Board Junction to Kempegowda International Airport. 

The route broadly follows this alignment: 

• Phase 2A runs along Outer Ring Road, covering major tech and commercial hubs between Silk Board and KR Puram 

• Phase 2B extends northwards from KR Puram, moving through key northern nodes before terminating at the airport 

• The combined corridor intersects with existing metro lines at interchange stations, enabling smoother east–west and north–south movement 

• Both phases are fully elevated, reducing land acquisition complexity compared to underground corridors 

• This alignment has been planned to serve both present commuter demand and projected urban expansion zones. 

Bangalore Metro Phase 2A Stations List 

Phase 2A includes stations positioned along ORR, each serving high-density employment and residential clusters. These stations are designed to integrate with nearby road networks and bus corridors. 

Stations under Bangalore Metro Phase 2A: 

Station Name	Key Area / Connectivity
Silk Board Junction	Major traffic interchange connecting South Bengaluru
HSR Layout	Residential and commercial hub
Agara Lake	Access to Sarjapur Road vicinity
Ibbalur	Proximity to ORR business parks
Bellandur	Large IT and office concentration
Kadubeesanahalli	Major tech campus zone
Kodibisanahalli	ORR residential stretch
Marathahalli	Key arterial road junction
Doddanekundi	Access to Whitefield-side areas
DRDO Sports Complex	Residential catchment area
KR Puram	Major interchange with existing metro line

Station names and alignments are based on official BMRCL documentation and publicly released project updates. 

Bangalore Metro Phase 2B Stations List 

Phase 2B stations are planned to serve North and North-East Bengaluru, connecting residential growth zones to the airport corridor. While the alignment is fixed, some station-area developments are still evolving. 

Key stations under Bangalore Metro Phase 2B include: 

Station Name	Key Area / Connectivity
KR Puram	Interchange station connecting Phase 2A and Phase 2B
Nagawara	Connectivity to existing metro corridors
Veerannapalya	Access to surrounding residential pockets
Kempapura	Serves North Bengaluru neighbourhoods
Hebbal	Major road and transit junction
Jakkur	Emerging residential zone
Yelahanka	Established residential and defence area
Airport City	Airport-linked commercial and business zone
Kempegowda International Airport	Direct terminal access

Station names and sequencing follow official corridor plans, with intermediate stations based on published civil and planning disclosures. 

Bangalore Metro Phase 2A & 2B Current Status 

Construction across Phase 2A and Phase 2B is ongoing, with progress varying by section. Authorities have consistently indicated that timelines may shift due to civil, land, and system-integration factors. 

Current status highlights include: 

• Phase 2A has completed substantial viaduct construction across ORR 

• Track laying and station structure work is underway in multiple sections 

• Phase 2B involves more complex coordination due to longer alignment and airport-zone clearances 

• Systems work (signalling, power, testing) will follow civil completion phases 

Benefits of Bangalore Metro Phase 2A & 2B 

The combined Phase 2A and 2B corridor delivers structural benefits beyond daily commuting. 

Key benefits include: 

• Improved public transport access along Outer Ring Road 

• Faster connectivity between IT corridors and North Bengaluru 

• Direct metro access to the airport region 

• Reduced dependence on private vehicles 

• Lower surface-level traffic congestion 

• Support for transit-oriented development along the corridor 

• Improved predictability of travel times for daily commuters 

  
  

For urban planning and real estate, these corridors act as long-term infrastructure anchors rather than short-term mobility upgrades. Metro Phases 2A and 2B are expected to act as real-estate catalysts by improving accessibility along key growth corridors and reducing travel times between employment hubs, residential clusters, and the airport. Studies of metro expansions in Bengaluru show that enhanced transit connectivity tends to increase demand for properties near stations, support higher rental and sales values, and encourage transit-oriented development around key nodes.  

Once operational, areas along the ORR and northern stretches such as KR Puram, Hebbal, and Devanahalli are likely to become more attractive to both end-users and investors, though such impacts vary over time and are influenced by broader market dynamics. 

Challenges and Delays in Bangalore Metro Phase 2A & Phase 2B 

Like most large-scale urban infrastructure projects, Phase 2A and Phase 2B have faced execution challenges. 

Key factors affecting timelines include: 

• Land acquisition and right-of-way constraints 

• Coordination with existing road and utility infrastructure 

• Contractor capacity and sequencing issues 

• Regulatory approvals near sensitive zones 

• Weather-related construction delays 

Authorities have acknowledged these challenges publicly and continue to issue revised progress updates instead of rigid deadlines. 

Bangalore Metro Phase 2A and Phase 2B represent a critical shift in how the city approaches long-distance, high-density commuting. By linking ORR, East Bengaluru, North Bengaluru, and the airport through a continuous metro corridor, these phases strengthen the city’s long-term mobility framework. While timelines remain fluid, the strategic value of these corridors is clear: better connectivity, reduced congestion, and infrastructure aligned with Bengaluru’s growth trajectory.
