Uttarakhand may get the worlds longest road tunnel approximately 30 km in the next few years. The National Highways Authority of India (NHAI) has invited bids for carrying out the feasibility study and preparing a detailed project report (DPR) for the tunnel, which would start from Jolly Grant Airport in Dehradun and end at Koti Colony near Tehri Dam in the poll-bound state.
Currently, the 24.5 km Laerdal tunnel in Norway is the longest road tunnel in the world.
The project will include a 7-10 km approach road at both ends.
Recently, Uttarakhand chief minister Pushkar Singh Dhami had sought approval from the Centre for the construction of a double-lane tunnel from Dehradun to Tehri Lake. The central government decided to give this task to the NHAI.
