**Executive Summary**
The National Highway Authority of India (NHAI) is constructing a 12 km greenfield, four-lane bypass in Dehradun to decongest urban traffic and improve regional connectivity to the Delhi-Dehradun Economic Corridor. The project, costing approximately Rs. 716 crores, has achieved 44 percent physical progress and is scheduled for completion by April 2027. It incorporates specific environmental and wildlife mitigation measures to ensure long-term sustainability while facilitating travel to neighboring states and tourist hubs.
**Key Points / Main Content**
**Project Specifications and Progress**
* The bypass is a 12 km long, four-lane, access-controlled greenfield alignment.
* The route connects Jhajhra (on NH-7) to the Delhi-Dehradun Economic Corridor near the Asharori Check Post.
* Current physical progress is at 44 percent, with a total capital cost of approximately Rs. 716 crores.
* The target completion date for the project is April 2027.
**Strategic Connectivity and Traffic Management**
* The highway acts as an alternate south-western route to divert non-destined traffic away from Dehradun’s urban core.
* It improves access to industrial areas such as Selaqui and towns including Vikasnagar, Herbertpur, and Paonta Sahib.
* The project enhances inter-state connectivity between Uttarakhand and regions in Haryana, Punjab, and Himachal Pradesh.
**Environmental Sustainability and Design**
* The "Right of Way" (width of the highway) is optimized at 30 meters—half the conventional 60 meters—to preserve forest cover.
* While the design speed is 100 kmph, speed is regulated to 80 kmph in specific stretches to minimize forest impact.
* Continuous fencing and signage for speed limits and wildlife zones are being installed to prevent human-wildlife conflict.
**Wildlife Mitigation Measures**
* A 350-meter-long Vehicular Over Pass (VOP) and a dedicated Cattle Over Pass (COP) are included for large animal movement.
* Infrastructure includes seven minor bridges and 21 box culverts tailored for wildlife support.
* Five dedicated Hume Pipe culverts are being constructed specifically for smaller fauna like reptiles and amphibians.
**Impact Analysis**

Construction of Dehradun Bypass to Decongest
Traffic and Strengthen Connectivity in Full Swing

Aimed at enhancing regional connectivity and decongesting traffic in Dehradun, National Highway
Authority of India (NHAI) is constructing a 12 km long Greenfield four-lane access-controlled bypass
connecting to Delhi-Dehradun Economic Corridor in the state of Uttarakhand. The project involves
development of a greenfield alignment from Jhajhra connecting the new Paonta Saheb-Ballupur section of
NH-7 and ending at Delhi-Dehradun Economic Corridor near Asharori Check Post in Dehradun District of
Uttarakhand. The project is being implemented at capital cost of around Rs. 716 crores and physical
progress of around 44 percent has already been achieved. The project is expected to be completed by April
2027.
Strategically designed as a fully access-controlled National Highway, the bypass will function as an
alternate south-western route, diverting non-destined traffic to bypass the urban core of Dehradun city
towards Selaqui industrial area, Vikasnagar, Herbertpur in Uttarakhand and Paonta Sahib in Himachal
Pradesh. The project will significantly help to reduce traffic congestion and vehicular pollution in
Dehradun. It will also improve inter-state connectivity to Northern regions including Haryana, Punjab and
Himachal Pradesh through Delhi Dehradun Economic Corridor.
The project has been designed with a focus on long-term sustainability. While the design speed will be 100
kmph, certain stretches have been planned with a regulated speed of 80 kmph to minimize impact on
forest land. In line with environmental considerations, the width of the Highway (Right of Way) has been
optimized to 30 meters, which is lower than the conventional 60 metres, thereby preserving forest trees
and maintaining ecological balance.
Given the project’s alignment through forest areas, several mitigation measures have been incorporated to
ensure protection of wildlife. These include construction of a 350-meter-long Vehicular Over Pass (VOP)
to facilitate safe movement of large animals, along with a dedicated Cattle Over Pass (COP). In addition,
seven minor bridges and 21 box culverts will be constructed to support movement of wildlife. Movement
of smaller fauna such as reptiles and amphibians will be facilitated through five dedicated Hume Pipe
culverts.
To further enhance safety and ecological protection, continuous fencing is being installed along the project
stretch, along with appropriate signage indicating speed limits and wildlife zones. These measures are
aimed at minimizing human-wildlife conflict and ensuring safe passage for animals across the forest area.
The project will also improve connectivity to key tourist destinations, including Mussoorie, thereby
supporting tourism growth in the region.
Upon completion, the bypass will provide substantial relief to residents of Dehradun by diverting heavy
and transit traffic away from the city, improving overall urban mobility and quality of life in the region.
