The Borivali-Thane twin tunnel will begin construction before the start of the monsoon season because the Mumbai Metropolitan Region Development Authority (MMRDA) has taken the necessary steps to carry out this crucial project that will significantly cut the amount of time it takes to travel between the two locations. The cost of the project has gone up by a few thousand crores as a result of the execution delay. Currently, the 24 km drive from Magathane (Borivali) to Tikuji-Ni-Wadi takes more over an hour (Thane). The trip will take only about 15 minutes after this 11.84km-long road project is completed beneath the Sanjay Gandhi National Park. On both ends (Thane and Borivali combined), this proposed project will feature 10.8 kilometres of twin tunnels plus an additional kilometre of approach roads. In total, a tunnel and 23.68km of new road work will be completed in the upcoming years. According to the designs, the East-West connectivity project will emerge next to Tikuji-Ni-Wadi at Manpada in Thane from Magathane's Ekta Nagar in Borivali. There will be connected tunnels for emergencies and three lanes in each tunnel for a total of six lanes. Costs for the project have increased from 112,350 million to over 132,000 million as a result of the impasse over its implementation. The National Board for Wildlife has granted the MMRDA wildlife clearance. To move the project further, environmental clearance is currently needed. An MMRDA official stated, We have established a four-year timeframe to carry out the project, which will be 23m below the surface. There will be lay-by space, fire extinguishers, ventilation equipment, security cameras, speed cameras, smoke detectors, etc. MMRDA SVR Srinivas, Metropolitan Commissioner, remarked. In addition to this tunnel, the Goregaon-Mulund Link Road has also been put up for bid by the BMC. Another project to connect the east and west will cross Sanjay Gandhi National Park with this one. 24 kilometres separate Borivali from Thane. Tunnel length as proposed: 11.84 km 23 metres below surface of tunnel Cost: 132,000,000,000
