Tamil Nadu has tentatively finalized a greenfield airport site for Hosur between Berigai and Bagalur in Krishnagiri district, following an Obstacle Limitation Surface (OLS) airspace survey, and is moving toward central approvals and land planning steps.
Where the site is
The preferred location lies east of Hosur city in Shoolagiri taluk, positioned between Berigai (around 25 km from Hosur) and Bagalur (around 12 km), and roughly 19 km from Attibele at the Karnataka border, enhancing access to the Bengaluru side of the region.
Why this site over Belagondapalli
Comparative OLS findings reportedly show fewer obstacles at Berigai–Bagalur (around 75) versus near the existing TAAL airstrip area (nearly 350), where hilly terrain and high-tension lines complicate airspace and capital costs, tilting viability toward the Berigai–Bagalur tract despite greenfield groundwork needs.
Connectivity tailwinds
The shortlisted site sits near the planned Bengaluru Satellite Town Ring Road (STRR) corridor by NHAI, a linkage expected to tighten Hosur’s connections with Bengaluru’s southeast and neighboring satellite towns, improving airport catchment and logistics potential across the border.
What’s next procedurally
- State action: Tamil Nadu aims to seek Ministry of Civil Aviation site clearance within weeks, while the Krishnagiri Collector prepares a land acquisition proposal on a 4–6 week timeline, signaling shift from evaluation to execution.
- Land footprint: Early indications suggest a requirement in the 2,000–2,300 acre range, with a portion already under government control, subject to final surveys and notifications.
- Airspace coordination: The state has initiated discussions with the Defense Ministry for controlled airspace, a standard step for greenfield facilities near active corridors.
Regulatory considerations near Bengaluru
Because Bengaluru International Airport Limited (BIAL) holds a concession restricting new international airports within 150 km until 2033, Hosur’s pathway will likely focus first on domestic and staged capacity, with full buildout expected to take several years even after approvals.
Economic rationale
Hosur’s manufacturing ecosystem—spanning autos, electronics, and MSMEs—creates strong freight and passenger demand fundamentals; a Hosur airport is positioned to unlock faster market access and talent mobility, complementing Bengaluru’s industrial belt and supporting a twin-city growth dynamic over time.
Capacity vision and timelines
Public signaling around capacity has referenced up to 30 million passengers annually in full buildout scenarios for a greenfield footprint, though final phasing and traffic ramp will depend on regulatory sequencing, land assembly, and regional airline strategies over the next 6–8 years.
What this means for stakeholders
- Industrial and logistics: Shorter lead times into Bengaluru’s east and Hosur’s OEM–supplier clusters, potential dedicated cargo planning, and improved shift-based workforce connectivity across districts.
- Real estate and land: Anticipated uplift along Berigai–Bagalur–Attibele corridors, with STRR adjacency amplifying node development and warehousing demand; due diligence on zoning, STRR alignments, and airport noise contours will be critical.
- Investors: A sequencing-dependent asset with strategic upside in a high-growth border market; milestones to monitor include MoCA site clearance, land notifications, STRR progress, and BIAL-related NOC contours.
Bottom line
The Berigai–Bagalur selection advances Hosur’s greenfield airport from study phase to pre-clearance execution, anchored by clearer airspace feasibility, emerging STRR connectivity, and strong cross-border demand drivers—setting the stage for a multi-year, phased aviation asset serving the Hosur–Bengaluru industrial region.
