The stretch spans across Kolathur Junction, Srinivasa Nagar, Villivakkam Metro, Villivakkam Bus Terminus, and Villivakkam Madras–Thiruvallur High Road stations.
The project involves development of 118.9-km three metro corridors (corridor III, IV and V) in Chennai and Tamil Nadu at an estimated cost of Rs 632.46 billion. It is mostly underground with an elevated section confined to a few short stretches and consists of 128 stations in total.
