Thane, 3rd January 2023: The Mumbai Metropolitan Region Development Authority (MMRDA) plans to commence construction of the Borivali-Thane twin tunnel before the onset of the monsoons. This is a critical project that will greatly reduce the travel time between the two destinations. The project has been delayed in the past, leading to its cost increases of a few thousand crores. The stalemate over the project’s implementation has meant cost escalating from Rs 11,235 crore to over Rs 13,200 crore.
The project consists of 10.8 km of twin tunnels and another kilometre of approach roads on both ends combined. The total construction will thus span 23.68 km. The project will be built beneath the Sanjay Gandhi national park and will cut the travel time from Thane to Borivali down to 15 minutes, from over one hour.
As per the plans, the East-West connectivity project’s alignment will be at Magathane’s Ekta Nagar in Borivali and emerge next to Tikuji-Ni-Wadi at Manpada in Thane. Each of the tunnels will have three lanes (six in total), along with interconnecting tunnels for emergency purposes.
