NHAI Releases New Guidelines for High-Speed Access-Controlled National Highways to Boost Safety
The rules standardize lane widths, safety measures and interchange design for upcoming 4-6 lane corridors, officials said.
- The National Highways Authority of India released comprehensive guidelines on Monday standardizing design and safety for High-Speed National Highways, supporting the Viksit Bharat 2047 roadmap for 50,000 km of High-Speed Corridors.
- To address observed variations in Detailed Project Reports, the Ministry introduced these regulations to ensure consistency across the National Highways network and strengthen road safety across projects.
- Infrastructure guidelines mandate lane configurations based on traffic projections: 70 meters for corridors handling 25,000–40,000 vehicles and 60 meters for those under 15,000 vehicles; a 1-metre-high boundary wall prevents "unauthorised access and entry of stray cattle."
- Detailed signage requirements include advance direction signs at 5 km, 2 km, 1 km, and 500 metres before exits, enabling drivers to anticipate entry and exit points; crash cushions at merging points reduce accident impact.
- These standards apply to all upcoming Greenfield and Brownfield High-Speed Corridors; currently, 3,052 km of such High-Speed National Highways are operational, with new frameworks governing future projects across India.
