The tunnel boring machine (TBM) S-1327A, named Kaveri, commissioned by Larsen & Toubro Limited, has successfully achieved a breakthrough at Adyar Junction Station as part of line 3 under package TU-02 of the Chennai metro phase 2 project.
Deployed in February 2023, TBM Kaveri was tasked to excavate a 1,228-metre tunnel from Greenways Road to Adyar Junction Station. It is one of the eight TBMs being utilised for the Chennai metro phase 2 project, which aims to construct a total of 12 kilometres of twin tunnels between Kellys Station and Taramani Road Junction Station.
