From May 23, toll charges at approximately 60 National Highway toll plazas in Tamil Nadu will see an increase, following the conclusion of the Assembly election model code of conduct. The National Highways Authority of India (NHAI) has revised rates for key highways connecting major cities such as Chennai, Madurai, Coimbatore, and Salem. The adjustments, linked to the Wholesale Price Index (WPI), will lead to a rise in costs ranging from 2.5% to 2.7% for various vehicle categories. While single journey tolls for most private vehicles remain stable, return journey fees have increased by around Rs 5 in certain areas, and commercial vehicle tolls have risen by Rs 10 to Rs 15. Additionally, local resident monthly pass fees have been raised to Rs 350. The increased tolls will significantly affect travel expenses, with estimates suggesting a rise of approximately Rs 80 for round trips between Chennai and Madurai. Concerns have been raised by freight operators regarding the impact on logistics costs, while consumer activists have criticized the toll hikes due to poor facilities at many plazas.
