Project Overview

The Delhi Dehradun Expressway is a 210 km greenfield and brownfield expressway connecting Delhi and Dehradun. The expressway (also known as Delhi-Saharanpur-Dehradun Expressway) is a planned six-lane (expandable to eight or even twelve lanes) expressway. It is developed by the National Highway Authority of India (NHAI) under an Engineering, Procurement, and Construction (EPC) Contract model. 

It will connect three states, including Delhi, Uttarakhand, and Uttar Pradesh, and reduce travel time by half. Currently, it takes 5-6 hours to travel. Upon its completion, the journey from Delhi to Dehradun will take only 2.5 hours.  

Once operational, it is expected to reduce traffic congestion, as the expressway features a separate 32 km-long, six-lane service road for city traffic. Furthermore, the expressway is expected to carry approximately 20,000 to 30,000 vehicles per day at an average speed of 100 km/h.  

Project Background

The Delhi Dehradun Expressway (also called National Highway 709 B) is an ambitious project of the National Highways Authority of India (NHAI) under the Bharatmala Pariyojana. Union Minister of Road Transport and Highways, Nitin Gadkari, first laid the foundation stone on 26 February 2021. Prime Minister Narendra Modi then laid the foundation stone again on 4 December 2021. 

The project is developed on an Engineering, Procurement, and Construction (EPC) basis, utilizing cutting-edge technologies to protect sustainability. It is part of India’s extensive expressway expansion plan, just like the Delhi-Mumbai Expressway. 

The expressway will relieve congestion on the Delhi NCT and further reduce traffic on the Delhi-Meerut Expressway and other connecting highways.

Delhi-Dehradun Expressway Opening Date

The Delhi-Dehradun Expressway is all set to become operational. On 14 April 2026, Prime Minister Narendra Modi will inaugurate the expressway, reducing travel time to 2.5 hours. Developed under four phases, some segments are already operational. These include Daat Kali to Asharodi (spanning 3.5 km) and Akshardham to Khekra (spanning 31.6 km).

Delhi Dehradun Expressway New Route 

The Delhi Dehradun Expressway, developed by the NHAI, is a 210 km (130 miles) expressway. It starts from Akshardham (Delhi) and ends at Dehradun, connecting Delhi and Dehradun via Saharanpur in half an hour (2.5 hours). 

Furthermore, the expressway route connects the three prime states, including Delhi, Uttarakhand, and Uttar Pradesh. It also crosses through some districts, including Baghpat, Baraut, Shamli, and Saharanpur. 

The expressway features two spurs that connect nearby cities. It includes a 50.7 km long six-lane Saharanpur-Roorkee-Haridwar Expressway. It will also connect to the Char Dham Highway. And another 121 km Ambala-Shamli six-lane Expressway.

Thus, it will boost connectivity between Hill Stations and pilgrimage sites in Uttarakhand and Uttar Pradesh.

Four Phases of Delhi Dehradun Expressway

The Delhi Dehradun Expressway is built in four phases. The first phase starts from Delhi and ends at the Eastern Peripheral Expressway (EPE). The second phase begins at EPE and extends to Saharanpur. The third phase goes from Saharanpur towards Rajaji National Park. The last phase runs from Rajaji National Park to Dehradun. Below is the description of each phase. 

Phase I - Delhi to the Eastern Peripheral Expressway (EPE)

The first phase of the Delhi Dehradun Expressway starts from the Akshardham Temple in Delhi and heads towards the Eastern Peripheral Expressway (EPE) interchange in Baghpat, Uttar Pradesh. It is a total of 32 km long, featuring a 6.4 km aerial corridor spanning from Geeta Colony to Khajoori Khas in Delhi. The other corridor is an 11.2 km long stretch in Uttar Pradesh. 

Phase I, a brownfield stretch, is reducing traffic congestion and travel times. Initially, it took one hour to travel from Delhi to Baghpat. Now, it only takes 25 to 30 minutes. It also spotlights the entry and exit points at Akshardham, Geeta Colony, and Mandola.

Phase II - EPE to Saharanpur

Phase II, a greenfield stretch, begins from the Eastern Peripheral Expressway (EPE) interchange near Baghpat and heads towards the Saharanpur Bypass (Uttar Pradesh). It is approximately a 118 km long six-lane stretch featuring seven interchanges and 60 underpasses. These interchanges and underpasses will help reduce traffic and ensure smooth connectivity through Baghpat and Shamli. 

Phase III - Saharanpur to Rajaji National Park

Phase III is a 40 km long brownfield stretch. It begins at the Saharanpur Bypass (Uttar Pradesh) and ends at Ganeshpur, near the entrance to Rajaji National Park (Uttarakhand). This phase will ensure the refurbishment of the existing highways. 

It focuses on pedestrian crossings and wildlife protection measures, including underpasses and eco-bridges, to minimize environmental impact in the ecologically sensitive Rajaji National Park area. 

Phase IV - Rajaji National Park to Dehradun

Phase IV of the Delhi Dehradun Expressway is a 19.5 km long brownfield stretch, highlighting Asia’s longest wildlife corridor. It starts from Ganeshpur, near Rajaji National Park, and ends at Dehradun (Uttarakhand).

This phase holds Asia’s longest wildlife corridor (12 km), including a 6-meter vertical clearance for elephants and other animals, a 2.322 km twin-tube tunnel, a 340-meter single-tube Daat Kali tunnel, and a 2.12 km at-grade hill section. 

By minimizing its environmental impact through eco-sensitive designs, the expressway traverses the Shivalik Hills and the Rajaji Tiger Reserve. 

Project Cost 

The total estimated cost of constructing the Delhi-Dehradun Expressway is INR 12,000 crore (approximately USD 1.44 billion). 

Project Scope

The following is the project scope of the Delhi-Dehradun Expressway

• High-Speed Travel: The expressway is designed for high-speed travel, with a speed limit of 100 km/h. 

• Carry Asia’s Longest Wildlife Corridor: A 12 km long corridor near Rajaji National Park (Uttarakhand). It further includes six animal underpasses and two elephant underpasses.  

• Reduced travel time: Currently, it takes approximately 5 hours to travel from Delhi to Dehradun. Upon the expressway’s completion, it will only take 2.5 hours. It will reduce travel time by half.

• Incorporation of Intelligent Traffic Management Systems (ITMS): This will enable real-time monitoring, enhance safety, and facilitate smooth travel.  

• Tunnels and infrastructure: It includes six entry and exit points, 113 underpasses, 76 km of service roads, 29 km of elevated highways, 5 ROBs, and 62 bus shelters. 

• Connectivity with other expressways: The Delhi Dehradun Expressway also connects with the NH-344, NH-58, and the Eastern Peripheral Expressway (EPE). 

Ecological measures under the expressway

• 340-meter tunnel near Dal Kali Temple: The aim was to avoid disturbing wildlife sanctuaries. 

• Use of Noise Barrier Devices: The expressway has installed noise barrier devices near the forest to reduce noise pollution.

• Use of Fly Ashes: The use of Fly Ashes during construction helps reuse industrial waste and protects the environment. 

• Sustainable water management technique: Water harvesting systems are executed along the expressway.
