Admin Key Highlights and Benefits:
• MLFF tolling system at Nemili Toll Plaza on the Sriperumbudur to Karaipettai section of NH-48 enabled with barrier-less tolling, allowing vehicles to pass without stopping
• Technology to reduce human intervention, travel time, fuel consumption, congestion and vehicular emissions at the toll plaza
• Ensures transparent, efficient and cost-effective toll operations
• Enhances seamless commuting and ‘Ease of Travel’ through ANPR and FASTag-based technologies
Becomes Second toll plaza in Tamil Nadu to adopt MLFF tolling system
Chennai, 13th November 2026: In a significant step towards modernising National Highway infrastructure and enhancing commuter convenience, NHAI has implemented Multi-Lane Free Flow (MLFF) tolling system at Nemili Toll Plaza on the Sriperumbudur–Karaipettai section of NH-48, making it the second toll plaza in Tamil Nadu to adopt this technology. The technology-driven initiative will enable faster, smoother and seamless journeys for National Highway users.
The barrier-less tolling system eliminates the need for vehicles to stop at toll plazas for toll payments, facilitating uninterrupted traffic movement. It leverages advanced technologies, including Automatic Number Plate Recognition (ANPR) and FASTag-based Electronic Toll Collection (ETC), to enable seamless and efficient toll operations. The initiative is aligned with the Government of India’s vision of delivering citizen-centric services through technology, further strengthening Ease of Living and Ease of Doing Business.
Multi-Lane Free Flow (MLFF): A Transformational Shift in Tolling
The introduction of MLFF marks a significant transformation in electronic toll collection across National Highways. By eliminating the need for vehicles to stop at toll plazas, the system will minimise human intervention in toll collection, reduce congestion and travel time, improve fuel efficiency and contribute to lower vehicular emissions. This will also enhance the overall travel experience for National Highway users.
NHAI is implementing MLFF-based tolling systems across various National Highways in the country in a phased manner. As part of this initiative, Tamil Nadu witnessed its first MLFF tolling system at Paranur Toll Plaza in October 2026. With the launch of the system at Nemili, the State now has its second barrier-less tolling facility, marking another milestone in the adoption of technology-driven National Highway infrastructure. For a seamless MLFF experience, National Highway users are required to maintain functional FASTag with sufficient balance to avoid Electronic Notice (E-Notice).
Implementation of MLFF has helped to strengthen the tolling ecosystem by enhancing transparency, reducing operational costs associated with setting up of physical toll plazas and improving overall efficiency in toll operations across the country.
