India’s upcoming high-speed National Highways will feature stricter design standards, including one-metre-high barriers to keep stray cattle off roads, advance warnings ahead of exits and highway widths determined by traffic requirements.
The National Highways Authority of India (NHAI) has issued new guidelines for the planning and design of four- and six-lane access-controlled National Highways.

The guidelines will apply to both greenfield and brownfield highway projects, while expressways have been kept outside their scope.
Access-controlled highways are designed to restrict entry and exit to designated points, preventing vehicles from directly accessing the highway from adjoining roads or properties.
According to the Ministry of Road Transport and Highways, the absence of separate design standards for high-speed National Highways had previously resulted in variations in Detailed Project Reports (DPRs).
The new guidelines aim to establish uniform standards for key aspects of highway development, including carriageway width, lane requirements, entry and exit points, interchanges and access-control measures.
The measures are intended to bring greater consistency to the planning and design of upcoming high-speed National Highway projects across the country.
