NHAI Clears ₹3,500 Cr, 42-Km Highway Connecting Dehradun & Mussoorie

Now Dehradun to Mussoorie in Just 30 Minutes

The Union government has formally approved the alignment of a 42-kilometre national highway. This project aims to strengthen road connectivity between Dehradun and Mussoorie. It will be developed at an estimated cost of around ₹3,500 crore. Execution has now been taken over by the National Highways Authority of India (NHAI), marking a key shift in responsibility for implementation.

Route Details: Jhajra to Library Chowk 

The proposed highway will begin at Jhajra and terminate at Library Chowk in Mussoorie. It will link NH-707A, also known as the Mussoorie–Kempty Falls Road, through the newly planned Chaskot–Khanji Nagar corridor.

Twin Tunnels to Define Highway Design

A major highlight of the project is the inclusion of two long tunnels. The first tunnel, stretching 2.9 kilometres, will pass beneath the George Everest region. The second tunnel will be 2 kilometres long and will cut through the Mussoorie hills. These structures are designed to allow vehicles to move through mountainous terrain without navigating sharp curves, steep gradients, or landslide-vulnerable sections.

Relief from Traffic Bottlenecks and Monsoon Disruptions

The existing Dehradun–Mussoorie road often experiences heavy congestion, particularly near the Galogi Power House. The alternative Kimari route is frequently shut during the monsoon. By starting from Jhajra, the new highway is expected to ease city traffic. At the same time, it will offer a more direct approach for tourists travelling from the Delhi NCR region.

Wadia Institute Tasked with Geological Safety Checks

Considering the ecological sensitivity of the Himalayan belt, NHAI has engaged the Wadia Institute of Himalayan Geology to assess mountain stability. The institute is conducting detailed studies of soil and rock conditions along the alignment. This is aimed at minimising the risk of landslides during and after construction.
