NHAI's 21 September 2026 design guidelines lock uniform 60-70m right-of-way and structure standards for 4-lane and 6-lane high-speed corridors, reshap

The National Highways Authority of India (NHAI) is moving toward a grade-separated fix for a high-crash corridor in Dehradun, even as district authorities push immediate traffic-calming interventions.
NHAI project director Saurabh Singh confirmed that a draft proposal for an elevated road from Asharodi to ISBT and ISBT to Miyawala has been submitted to the Central Government for approval.
The alignment is designed to give heavy vehicles a dedicated route, removing the mixed-traffic conflict now triggering repeated accidents on the Delhi–Dehradun highway.
The immediate trigger was a crash in the Mohabbewala area, after which Dehradun district magistrate Ashish Chauhan and senior superintendent of police Pramendra Singh Dobal inspected the stretch.
They directed NHAI to install additional signboards and rumble strips, and ordered a detailed technical investigation covering:
- Road engineering
- Identified black spots
- Overspeeding and traffic violations
Singh said NHAI has already installed around 50 signboards along a 100-metre stretch. That density is itself a signal: when a corridor needs that many warnings in 100 metres, signage has reached the limit of its effectiveness.
The structural answer is separation, not messaging.
For contractors and EPC players, the elevated corridor is the material item. It remains a proposal pending Central Government approval, but it signals NHAI's intent to convert an urban accident black spot into a heavy-vehicle grade separator.
Execution and funding clarity will only emerge once the Ministry of Road Transport and Highways clears the draft.
The near-term reality is that district administration is directing NHAI on safety response, placing delivery accountability on the highway authority while the permanent solution waits in the approval pipeline.
Interim measures are low-value, fast-deployable interventions; the commercial upside sits in the eventual elevated-road package.
Road-safety enforcement is moving from signage-led mitigation to grade-separated heavy-vehicle corridors, and district-level pressure is accelerating capital proposals that would otherwise sit in the planning queue.
