The breakthrough marks the successful completion of a crucial stretch of underground tunnelling, underscoring the steady progress of the Purple Line project. The achievement is expected to accelerate civil works and bring the corridor closer to operational readiness.
TBM ‘Durga’ bored through challenging geological conditions while maintaining high standards of safety and engineering precision. The successful tunnelling operation reflects the technical expertise deployed in executing complex underground infrastructure in densely populated urban areas.
The Joka–Esplanade Metro Corridor is being developed to enhance east-west connectivity across Kolkata by providing a modern, efficient and sustainable public transport system. Once completed, the corridor will reduce travel time, improve last-mile connectivity and help decongest road traffic.
The successful breakthrough by TBM ‘Durga’ represents another important milestone in the expansion of Kolkata Metro, reinforcing the Government’s commitment to strengthening urban mobility through world-class metro infrastructure and sustainable transportation solutions.
