The Delhi–Dehradun Expressway is set to significantly improve connectivity between the national capital and Uttarakhand, reducing travel time to around 3–4 hours. The 210-km project is expected to enhance access to key destinations such as Dehradun, Mussoorie and Char Dham pilgrimage sites, supporting tourism growth in the region. Improved road infrastructure is also likely to benefit local businesses and increase visitor footfall across the state.
