A major infrastructure push is set to transform connectivity between Dehradun and Mussoorie as the National Highways Authority of India has cleared a 42-km greenfield highway project aimed at sharply reducing travel time between the two hill destinations. The proposed corridor is expected to cut the journey from nearly 90 minutes during peak tourist seasons to around 30 minutes.
The project, with an estimated investment of Rs 3,500 crore, will originate at Jhajhra in Dehradun and extend up to Gandhi Chowk in Mussoorie. It is designed to serve as a faster and more reliable alternative to the existing 34-km hill road, which frequently faces heavy congestion due to tourist inflow and limited carriageway width.
A defining component of the new alignment is the construction of two strategically planned tunnels to navigate the rugged Himalayan topography. One of the tunnels, approximately 2.9 km in length, will pass beneath the George Everest peak, while another two-km stretch will be developed ahead of the Everest House section. These underground passages are expected to help bypass steep gradients, sharp hairpin bends and landslide-prone zones that currently slow down traffic and pose safety concerns.
By minimising exposure to vulnerable hillside stretches, the tunnel-based design aims to enhance travel safety and ensure uninterrupted vehicular movement, particularly during monsoon months when slope instability often disrupts access. The improved connectivity is also likely to boost tourism, ease logistics movement and strengthen the overall transport network in Uttarakhand’s hill region.
With terrain-sensitive engineering at its core, the Dehradun–Mussoorie highway project signals a decisive step toward modernising mountain road infrastructure while addressing long-standing traffic bottlenecks on one of the state’s busiest routes.
