The scarcity of rock and soil, crucial elements for highway construction, has become a bottleneck in the development efforts. This challenge arises from insufficient availability of these materials, impeding the construction teams' ability to maintain the desired momentum. The NH-66 project is of paramount importance, being a key transportation artery, and any delay in its development can have cascading effects on regional connectivity and economic activities.

The Thiruvananthapuram region, like many other areas, underscores the broader challenges faced by infrastructure projects in balancing resource availability and construction demands. The authorities are likely to strategise and address the shortage promptly to ensure the timely completion of the NH-66 development, minimizing disruptions and optimising resources for efficient progress in this critical transportation initiative.
