Hundreds of residents who attended the meeting convened by the Mumbai Metropolitan Region Development Authority (MMRDA) on Saturday voiced their opposition to the ambitious Thane-Borivali twin tunnel project, reported news agency PTI.
The 11.8-kilometre tunnel, estimated to cost Rs 16,600 crore, aims to reduce the distance between Borivali – located at the northern tip of Mumbai – and Thane by 12 kilometres. This would cut down the travel time down to mere minutes compared to the more than two hours it currently takes. The foundation stone for the project was laid by Prime Minister Narendra Modi on July 13 last year.
