NHAI Guidelines to Standardise Design and Infrastructure for Multi-Lane Free Flow Tolling on Four-Lane and Above National Highways

The National Highways Authority of India (NHAI) issued guidelines to standardise the design and infrastructure for barrier-less Multi-Lane Free Flow (MLFF) tolling on four-lane and above National Highways to eliminate traffic queues and waiting times.

• The guidelines will apply to all future and under-construction National Highway projects, with projects at the Detailed Project Report (DPR) stage incorporating the new design.
• Projects already awarded or under construction will adopt the changes through applicable contractual provisions.
• NHAI field offices have been directed to incorporate the prescribed requirements in upcoming projects and facilitate their adoption in ongoing projects.
• The guidelines prescribe uniform requirements for toll plaza layouts, lane configuration, gantries, road infrastructure, lighting, signage, and supporting facilities.
• The guidelines provide for construction of an administrative building-cum-operations and maintenance centre for efficient management of toll plaza operations.
