The entity that handled the construction of the Chengala–Neeleshwaram stretch of NH-66 in Kerala’s Kasaragod district has been banned from future highway projects after a slope protection structure collapsed on 16 June.

According to the National Highways Authority of India (NHAI), the incident occurred due to improper design, weak slope protection, and a poor drainage system.

NHAI takes action against concessionaire

Megha Engineering and Infrastructure Ltd., the contractor responsible for the collapsed stretch, has been barred from participating in future bids. A Show Cause Notice has also been issued, proposing a one-year debarment and a fine of up to Rs 9 crore.

Company to fix damage at own cost

The project falls under the Hybrid Annuity Mode (HAM), which requires the contractor to maintain the road for 15 years. As per this model, Megha Engineering must now rebuild the damaged slope at its own expense.

Expert panel to inspect site and suggest solutions

An expert committee has been formed to review the incident and recommend corrective measures. The panel includes a senior scientist from the Central Road Research Institute (CRRI), a retired professor from IIT Palakkad, and a representative from the Geological Survey of India (GSI).

They will examine the design and construction quality of NH-66 in Kerala and propose detailed technical solutions. NHAI has assured that all necessary steps are being taken to address the issue and prevent such failures in future.
