Union Minister Ashwini Vaishnaw announced a new underground tunnel project in Delhi designed to connect the Dwarka Expressway with South Delhi [1].
This project represents a critical effort to resolve chronic traffic congestion in the capital while preserving the Delhi Ridge. By moving transit underground, the government aims to improve urban connectivity without compromising the region's primary ecological lungs.
The project will utilize Tunnel Boring Machine (TBM) technology to excavate the path beneath the Delhi Ridge [1]. This specific engineering approach is intended to ensure that the surface ecosystem remains undisturbed during construction [1].
The tunnel is part of a larger infrastructure push across Delhi and Uttar Pradesh. The total cost for these combined initiatives is approximately Rs 14,115 crore [2]. Specifically, the Delhi tunnel project is budgeted at Rs 6,969.67 crore [3].
Officials said the tunnel is expected to be completed within two and a half years after construction begins [1]. The six-lane facility will serve as a vital link for commuters moving between the western suburbs, and the southern districts of the city [3].
Vaishnaw said the use of TBM technology allows the government to expand the city's road network while maintaining environmental standards. The project seeks to balance the demands of a growing population with the necessity of protecting urban green spaces [1].
“The tunnel is expected to be completed within 2.5 years of construction start.”
The use of Tunnel Boring Machines (TBM) signifies a shift toward 'invisible infrastructure' in Delhi, where environmental constraints prevent traditional surface expansion. By bypassing the Delhi Ridge, the government is attempting to avoid the legal and ecological battles that typically accompany highway construction in protected zones, setting a precedent for how India may handle future urban transit projects in environmentally sensitive areas.
