The new terminal building has been built at a cost of Rs. 1,260 crores.

"The new integrated terminal building at Chennai Airport, spanning an area of 2,20,972 sqm, is set to cater to the growing air traffic in the state of Tamil Nadu. It's also a reflection of the government's commitment towards providing high-quality infrastructure to travellers," the civil aviation ministry tweeted.

The T-2 (Phase-1) building will increase the airport's passenger capacity from 23 million to 30 million per year.

Sharing glimpses of the new terminal on Twitter, PM Modi said it will be an important addition to Chennai's infrastructure. "It will boost connectivity and also benefit the local economy," he tweeted.
