The newly inaugurated Delhi–Dehradun expressway reduces travel time from six to seven hours to two and a half hours and runs largely through western Uttar Pradesh, with 135 km of the 212-km corridor, around 64 per cent, in the state. Built at an estimated cost of Rs 120 billion (Rs 120 bn) over four years, the six-lane access-controlled road is envisaged as a major infrastructure push for multiple districts. The initial 18-km stretch has been kept toll-free to ease local movement.

It links to the Eastern Peripheral Expressway at Mandola and traverses Ghaziabad, Baghpat, Shamli and Saharanpur within Uttar Pradesh, with Baghpat and Saharanpur covering roughly 45–50 km each and Shamli about 35–40 km. Interchanges at Khekra, Baraut and other points connect local towns to the corridor and preserve regional accessibility.

The Baghpat stretch is entirely greenfield and is expected to prompt changes in land use, with logistics hubs, warehouses and real estate projects anticipated along the route. Officials said the expressway should attract investment to districts previously bypassed in industrial growth and improve access for agro-processing and manufacturing. An interchange near Deoband in Saharanpur is intended to enhance passenger and freight movement before the road enters Uttarakhand.

The route includes 113 underpasses, five railway overbridges, 62 bus shelters and 16 entry and exit points to enable uninterrupted travel. Advanced surveillance systems and sensors have been installed to detect accidents quickly, with emergency assistance expected to arrive within ten minutes. The speed limit has been capped at 100 km/h and a 12-km elevated wildlife corridor through the Rajaji Tiger Reserve has been incorporated to allow animal movement beneath the road.

Authorities noted that improved connectivity is likely to boost economic prospects in western Uttar Pradesh and create job opportunities for local youth, while faster routes should reduce transport time and costs for farmers and help secure better prices for perishable produce. Tolls have been fixed at Rs three per kilometre, making a one-way journey from Delhi to Dehradun approximately Rs 675, with discounts on return trips within 24 hours.
