Chennai Airport to Kilambakkam Metro Rail Project Work Begins; Traffic Relief Expected on GST Road
Chennai is gearing up for a major transportation upgrade as the Chennai Airport to Kilambakkam Metro Rail project has officially entered the initial stage of execution. The long-pending metro extension project is expected to improve connectivity between the airport and southern suburban regions while significantly reducing traffic congestion on GST Road.
The proposed metro corridor will directly connect the Chennai International Airport with the Kilambakkam Bus Terminus, one of Tamil Nadu’s largest integrated bus terminals serving passengers travelling to southern districts.
Direct Metro Connectivity from Airport to Kilambakkam
At present, passengers travelling from Chennai Airport to Kilambakkam Bus Terminus rely on suburban trains, MTC buses and private transport. This has resulted in severe traffic congestion across major suburban stretches including:
- Pallavaram
- Chromepet
- Tambaram
- Perungalathur
- Vandalur
Residents and commuters have repeatedly demanded a direct metro rail connection to ease travel difficulties and improve public transport accessibility in South Chennai.

The Tamil Nadu government has approved the Detailed Project Report (DPR) for the metro rail extension from Chennai Airport to Kilambakkam.
Project Highlights:
Total Project Cost: Rs 9,335 crore
Route Length: 15.46 kilometres

The corridor will offer seamless connectivity between key transport hubs including the airport, Tambaram railway station and Kilambakkam bus terminal.
