TN to study alternate sites for Chennai’s second airport, Hosur project in view
Tamil Nadu plans to explore alternate sites for Chennai’s second airport while showing interest in Hosur. A CM-led review indicates expected disclosures soon, with Parandur still unlikely to be dropped. Defence Ministry approvals are needed for Hosur’s airspace.
Key takeaways
- Tamil Nadu will examine alternative sites for a second Chennai airport.
- Hosur is also under consideration, subject to defence ministry airspace approvals.
- Parandur’s fate remains uncertain, with land acquisition halted and officials suggesting it is unlikely to be revisited.
- A government disclosure on plans for both airports was anticipated soon after August 23, 2026.
What Happened
The Tamil Nadu government has decided to explore alternative sites for establishing Chennai’s second airport and is also keen on developing an airport at Hosur. Chief Minister C. Joseph Vijay chaired a review meeting on Chennai’s second airport at the Secretariat. Sources indicated that the government would likely outline its plans for both projects within a few days. There is no government order indicating Parandur has been dropped, and land acquisition for that site has been halted for several months.
During the DMK government under M. K. Stalin, 1,700 acres of land were acquired and site clearance plus in-principle approval were obtained for the Parandur project. In recent weeks, the government reportedly considered expanding Meenambakkam airport and evaluating several alternative sites, including one in Chengalpet district. Officials described it as very unlikely that Parandur would be reconsidered. For Hosur, approval from the Defence Ministry to relax air-space restrictions at the chosen site is required. One source asserted the Hosur project will be built and that the state would address air-space constraints.
Why It Matters
The move signals a strategic shift in how Tamil Nadu plans its aviation infrastructure, with potential implications for land use, regional connectivity, and budget priorities. If Parandur is no longer prioritized, timelines could stretch, while proceeding with a Hosur project depends on federal clearance, potentially affecting the pace of development. A formal government disclosure in the near term could clarify which sites will advance and what approvals remain necessary.
Background
Parandur was previously cleared for the second Chennai airport, with land acquisition completed and a readiness framework in place during the prior administration. Opposition by the ruling party TVK to land acquisition for Parandur occurred before elections. In the last several weeks, the Tamil Nadu government signalled consideration of alternate sites, including a location in Chengalpet district, and the possibility of expanding Meenambakkam airport as part of the broader plan.

If Parandur remains unlikely, timelines for a new site could extend, with estimates suggesting a multi-year horizon for a new location to become operational, contingent on approvals and construction decisions.
