Uttarakhand chief minister Pushkar Singh Dhami has sought approval from the Centre for the construction of a double-lane tunnel from Dehradun to Tehri Lake. That the tunnel is likely to be a single tube with two lanes for up and down traffic. But everything depends on the feasibility of the project. Only a detailed study will find out how the tunnel would have to be constructed. The successful DPR consultant will also carry out the traffic study to project the likely traffic through the tunnel.
