Construction of a key bypass aimed at decongesting traffic in Dehradun and improving regional connectivity is progressing steadily, with nearly 44 per cent of the work already completed, the Ministry of Road Transport and Highways said. The 12-kilometre four-lane access-controlled highway is being developed by the National Highways Authority of India (NHAI) at an estimated cost of Rs 7,160 million (Rs 7,160 mn) and is expected to be completed by April 2027. The project has been positioned as a strategic link to the Delhi-Dehradun Economic Corridor.

The Ministry said the bypass will connect Jhajhra to the corridor near the Asharori check post and link with the Paonta Saheb-Ballupur section of National Highway seven, providing an alternate south-western route to divert non-destined traffic away from Dehradun’s urban core. The design aims to reduce congestion and vehicular pollution in the city while safeguarding travel times for through traffic. Alignment choices have been made to balance efficiency and minimal urban intrusion.

Planners expect the bypass to significantly improve access to the Selaqui industrial zone, Vikasnagar and Herbertpur in Uttarakhand, as well as Paonta Sahib in Himachal Pradesh, and to strengthen connections with Haryana and Punjab via the economic corridor. Design parameters include a design speed of 100 kmph with regulated stretches at 80 kmph to minimise environmental impact, and a right of way optimised to 30 metres to reduce tree cutting and preserve forest cover.

Given that parts of the alignment pass through forest areas, the scheme incorporates several wildlife protection measures, including a 350-metre vehicular overpass and a dedicated cattle underpass to facilitate safe movement of animals. The route will include seven minor bridges, 21 box culverts and five Hume pipe culverts, together with continuous fencing and signage indicating speed limits and wildlife zones. The Ministry indicated that once operational the bypass should enhance urban mobility, improve quality of life for residents and provide better access to tourist destinations such as Mussoorie.
