AAI Submits Hydrology Report to WRD for Chennai Airport Corridor

21 Jan 2026 CW Team

The satellite terminal, first proposed nearly eight years ago, is aimed at easing congestion by handling additional aircraft and passenger traffic while optimally utilising remote bays at the airport. Although the project remained stalled for several years, it gained renewed momentum in 2024 after AAI revived the proposal.

According to officials, the Tamil Nadu government had earlier informed AAI that additional land could not be provided to establish surface connectivity to the proposed terminal. In response, AAI submitted a revised proposal early last year, suggesting the construction of an elevated corridor from National Highway 32 to provide direct access to the satellite terminal without acquiring extra land.

As per the new plan, the four-lane elevated corridor would originate near Madha Arts and Science College at Thandalam, cross the Adyar River, and terminate at the satellite terminal entry point within the airport premises. Since the alignment involves placing pillars within the river, the State government sought a detailed assessment of its potential impact on water flow.

An AAI official said the WRD had asked for a hydrological impact study to examine whether the proposed pillars could obstruct the Adyar river’s flow during different conditions, including dry periods, monsoon rains and floods. “We requested the Centre for Water Resources, Anna University, to carry out the study. The report has now been submitted to the WRD,” the official said.

AAI officials said approvals are also required from the Central Pollution Control Board before work can proceed. Once the necessary clearances are obtained, AAI will allocate funds for the construction of the satellite terminal and the elevated corridor.

“The satellite terminal could function either as a full-fledged passenger terminal or as a dedicated cargo terminal. With the proposed Parandur airport likely to take another four to five years, this facility will provide significant relief to the city’s growing aviation demand,” an official added.
