A Look At 5 Longest Rail And Road Tunnels In India
Tunnels have a vital role to play in improving connectivity between cities. Urban streets are becoming more and more congested, thus, making tunnels a feasible infrastructure option. Plus, given the topography of our country which includes the breathtaking Himalayas, Vindhyas, Western Ghats and Satpuras, tunnels become an important feature of the road and rail network in India.
Tunnel engineering is an interesting discipline of civil engineering and requires specialised skills, in-depth risk assessment and robust safety measures. India is making rapid advancement in the construction of tunnels. Spanning a length of about 950 kilometres, many tunnel projects are in the under-construction stage and approximately 2,500 kilometres, are under various stages of planning. Here's a look at the 5 longest rail and road tunnels in the country.
