NHAI Introduces New Guidelines for Design and Development of Access-Controlled High-Speed National Highways
The National Highways Authority of India (NHAI) has released comprehensive guidelines for planning and designing High-Speed Access-Controlled National Highways, excluding Expressways. These guidelines aim to bring uniformity in Detailed Project Reports, improve road safety, and support the Viksit Bharat 2047 roadmap. They apply to upcoming 4/6 lane Greenfield and Brownfield corridors.
Why It Matters
The source discusses infrastructure policy and highway guidelines by NHAI under the Ministry of Road Transport & Highways, which can be relevant for government scheme and national infrastructure questions in competitive exams.
In Simple Words
NHAI has introduced new guidelines for planning and designing High-Speed Access-Controlled National Highways, excluding Expressways. These rules aim to bring uniformity to Detailed Project Reports, strengthen road safety, and boost operational efficiency across upcoming 4/6 lane Greenfield and Brownfield corridors.
The guidelines support the goal of developing 50,000 km of access-controlled corridors under Viksit Bharat 2047. They standardize lane configurations based on traffic flow, mandate interchanges at major crossings, and require a 1-metre-high boundary wall to prevent unauthorized access and stray cattle.
Key Points
- NHAI released comprehensive guidelines for High-Speed Access-Controlled National Highways other than Expressways.
- Guidelines align with the vision of Viksit Bharat 2047 and a roadmap for 50,000 km of access-controlled corridors.
- Guidelines apply to all upcoming 4/6 lane Greenfield and Brownfield High-speed access controlled National Highways.
- Traffic up to 15,000 vehicles with 4-lane highway 4-lane structures requires a 60-metre width.
- Traffic between 15,000 and 25,000 vehicles with 4-lane highway 6-lane structures requires a 70-metre width.
- Traffic between 25,000 and 40,000 vehicles requires a 70-metre width for 6-lane highway 6-lane structures.
- A 1-metre-high boundary wall must be constructed along the outer edge to prevent encroachments and stray cattle.
