The National Highways Authority of India (NHAI) is closing in on a milestone that promises to cut travel time between Ernakulam and Thiruvananthapuram to just two-and-a-half hours.
The extensive widening and modernisation of National Highway 66 (NH66), which spans 644 km from Thalappady in Kasaragod to Mukkola in Thiruvananthapuram, is now over 60 per cent complete, setting the stage for a dramatic transformation in long-distance travel across the state. The six-laning project, one of the largest infrastructure undertakings in Kerala under the Bharatmala Pariyojana, is designed to support a maximum speed of 100 kmph. The overhaul aims not only to boost travel efficiency but also to curb congestion and reduce emissions by ensuring uninterrupted traffic flow. Notably, four stretches of the highway are set to open within a month, while work on other sections such as the Edappally-Moothakunnam and Aroor-Thuravoor elevated corridors has reached 60 to 65 per cent completion.
The entire NH66 stretch is being designed as a signal-free corridor, barring a single exception at Madavana Junction, to support seamless mobility. The elimination of right turns and direct U-turns will be enforced through the construction of service roads and underpasses. Elevated corridors such as the 12.75-km Aroor-Thuravoor highway are being constructed with three designated exit ramps to enhance access while minimising surface-level congestion. However, this leap in road infrastructure comes with a financial trade-off—commuters will be required to pay additional tolls at points like Kumbalam, Eramalloor, and Kalavoor to access elevated sections, although service roads remain a free alternative.
The NH66 project is a cornerstone of the state’s vision for equitable and sustainable mobility. By reducing fuel consumption, cutting emissions, and shrinking commute times, it contributes directly to carbon mitigation and supports the creation of cleaner urban and rural environments. Furthermore, the exclusion of at-grade traffic junctions reflects a shift toward high-speed, uninterrupted travel essential in fostering economic activity and improving logistics. Simultaneously, planning is underway for a 121-km greenfield expressway between Palakkad and Kozhikode, which is expected to significantly decongest the heavily burdened NH966. Once executed, the proposed high-speed corridor will further catalyse connectivity in northern Kerala, promising a smoother, quicker commute of just two hours across this stretch.
As Kerala pushes the envelope on road infrastructure, the emphasis remains firm on enabling fast, inclusive, and environmentally sound transportation. While toll costs are a point of contention, the long-term payoff in reduced pollution, increased road safety, and economic stimulus is set to redefine the way Keralites travel. The completion of NH66’s widening and the proposed new expressway stand to reshape mobility in the state setting benchmarks for future transport projects across the country.
