The NH 66 expansion project in Kollam has hit a major roadblock due to structural collapses and safety concerns, pushing completion dates to late 2027.

Key Takeaways

  • NH 66 expansion deadlines for key sections moved to late 2027.
  • A structural collapse at Mylakkadu has necessitated a design shift to a viaduct.
  • Expert committees from IIT Delhi and IIT Palakkad are reviewing soil stability.

The ambitious expansion of National Highway (NH) 66 in Kollam is currently mired in significant hurdles, including technical setbacks and mounting safety concerns. Spanning approximately 63 km, the project's progress has been drastically slowed, leading to massive revisions in official completion timelines.

According to recent updates, the deadline for the Kottankulangara–Kollam Bypass section has been pushed from October 2024 to December 31, 2027. Similarly, the stretch from the bypass to Kadambattukonam has seen its timeline extended from March 2025 to June 30, 2027. These delays come as a blow to commuters expecting smoother connectivity by the end of this year.

Why This Matters

BozokMedia analysis shows that such prolonged delays in critical infrastructure projects create a ripple effect, increasing construction costs and delaying the economic benefits of improved logistics in the Kerala region. The structural integrity of the highway is now the primary focus to prevent further mishaps.

The collapse of the reinforced earth (RE) wall at Mylakkadu has forced a complete reassessment of the structural design for the entire stretch.

A critical turning point occurred on December 5, when an RE wall collapsed at Mylakkadu during its final construction phase. In response, Union Minister for Road Transport and Highways Nitin Gadkari confirmed that an expert committee, including geotechnical specialists from IIT Delhi and IIT Palakkad, is conducting rigorous soil tests and borehole investigations to ensure future stability.

Historical Background

The NH 66 expansion is part of a larger national initiative to modernize India's coastal highways. While intended to revolutionize travel along the western coast, the project in Kerala has faced recurring challenges due to complex terrain and high-density residential areas.

Did You Know?: The project involves constructing several major bridges, including the Kallumthazham and Kadavoor bridges, which are currently in the critical girder casting phase.

Frequently Asked Questions

1. Why was the NH 66 project deadline extended?
The extension is due to structural failures, such as the wall collapse at Mylakkadu, and the need for extensive geotechnical safety audits.

2. Who is investigating the safety of the highway?
Expert committees from IIT Delhi and IIT Palakkad are currently evaluating the structural safety of all earthen embankments.
