CMRL completes tunnel between Madhavaram High Road and Moolakadai after long delay

The delay was primarily due to issues with constructing the necessary shaft at the Moolakadai Metro Station. The tunnel boring machine 'Servarayan' faced challenges, including the need to close borewells and arrange alternative water sources for residents.
