Chennai is set to bolster its aviation infrastructure with the development of a second airport in Parandur, Tamil Nadu, spanning 5,368.93 acres.

The project, estimated at a total cost of ₹ 32,704.92 crore, will unfold in four phases, with a focus on expanding passenger terminals. Terminal 1, 2, and 3 will cover extensive areas of 3,45,758 sq. mtrs., 4,76,915 sq. mtrs., and 5,05,495 sq. mtrs., respectively. Additionally, a cargo terminal and truck docking area will occupy 2,30,500 sq. mtrs.

With the existing Meenambakkam airport nearing capacity, the new Parandur airport aims to alleviate congestion. To address environmental concerns, Tamil Nadu Industrial Development Corporation (TIDCO) is preparing a hydrogeological report to guide mitigation efforts.

Connectivity is a crucial aspect of the project. Plans include the construction of approach roads linking the site to the Bengaluru-Chennai Expressway. Furthermore, the Tamil Nadu government is spearheading the development of a six-lane Airport Link Road to seamlessly integrate the airport with the existing Bengaluru-Chennai NH-48.

The proposed route is slated to originate near the Airport Expressway (NE-7) drop junction, with its terminus intersecting NH-48 near Attuputhur. However, the final alignment of this crucial link road is yet to be determined.

Construction is scheduled to commence in January 2026, with the completion of the first phase anticipated by December 2028. Subsequent phases will follow, culminating in the final phase’s completion by December 2046. This ambitious endeavor underscores Chennai’s commitment to enhancing its aviation infrastructure to meet growing demands and ensure sustainable development.
