In a bid to protect wild animals including the endangered ‘one-horned’ rhinos from being hit by vehicles, the Centre is planning to construct a flyover over NH-37 that passes through Kaziranga National Park in Assam. The flyover over NH-37 is proposed at 35 kilometer in length, and will have three segments; the first segment which will be around 18 kilometer in length will be the longest in India more than the length of the PVNR Express Highway in Hyderabad, which is 11.6 kilometer long.
NHAI (National Highways Authority of India) is preparing the detailed project report at present and the total cost of the flyover over NH-37, which will be 11 metres wide, is expected to be around INR 2,600 crore. The work on the DPR is expected to be over within the next two months. Once that is done, the tender process would begin and work on the flyover over NH-37 is expected to start from next year. The NH 37 is also an animal corridor and used by small and big animals including elephants and rhinos. The main purpose for constructing the flyover over NH-37 is to protect the animals from being hit by vehicles while they cross the highway.
