Work on the Thane-Borivli underground twin tunnel, passing beneath the Sanjay Gandhi National Park, is set to commence in the coming months. The project is expected to excavate around 3.5 million cubic metres of soil, which equates to the capacity of approximately 1,40,000 large trucks. Three potential dumping sites have been proposed for the soil disposal.

An MMRDA official involved in the project said, “The Thane-Borivli Underground Tunnel Project (Package-2) is anticipated to excavate about 3.5 million cubic metres of soil. Megh Engineering and Infrastructure Ltd, the contractor, has identified three alternative dumping sites near Mankoli, Kalher, and Ranjnoli for this material.
