Description	The Thane–Borivali Twin Tunnel project involves the construction of the country’s widest and longest urban road tunnel in Mumbai. It features an 11.8 km twin tunnel system, with 5.75 km excavated from Borivli and 6.09 km from Thane, passing beneath the Sanjay Gandhi National Park. The project aims to reduce travel time between Thane and Borivli from 60–90 minutes to just 15 minutes, easing congestion and pollution. It uses four 13.34-metre Herrenknecht hard-rock Tunnel Boring Machines (TBMs) and includes advanced safety features such as ventilation, fire-fighting units, cross-passages, smoke detection, and LED guidance boards. The project is led by MMRDA and executed by MEIL.
