NHAI rolls out uniform design norms for high-speed access-controlled highways
NHAI has introduced a uniform design framework for high-speed access-controlled national highways to standardise planning and design as India expands its fast-road network.
The National Highways Authority of India (NHAI) has introduced a uniform design framework for high-speed, access-controlled national highways, a move aimed at bringing consistency to the way such corridors are planned and engineered.
The framework sets out common design standards for high-speed access-controlled highways, which allow traffic to move without interruptions from side roads, intersections or local access points. At present, such corridors are developed under varying design approaches; the new norms are intended to create a single reference for planners and designers.
The decision comes as India pushes ahead with the expansion of its high-speed road network, with access-controlled corridors seen as a key element of that build-out. By standardising design, the authority expects planning and execution of these projects to become more uniform across regions.
The framework applies to national highways built to high-speed, access-controlled specifications. Further details on the norms were not immediately available in the source material.
