meters, passing beneath the Adyar River for 300 meters with an overburden of 10 to 13 meters. Two Earth Pressure Balancing (EPB) Tunnel Boring Machines (TBMs), named 'Kaveri' and 'Adyar', are crucial for this project. TBM Kaveri has successfully completed its tunnel drive and achieved a breakthrough at the Adyar shaft, navigating through mixed geological conditions. The machine encountered hard rock formations below parts of the Adyar River, requiring 65 cutter head interventions. TBM Adyar is currently 277 meters away from the Adyar shaft and is expected to reach its destination by November 2024.

The Phase 2 project promises to improve urban mobility and contribute to Chennai's sustainable development goals.
