Comprehensive Post-Construction Evaluation of Kishoreganj-Karimganj-Chamraghat Highway in Bangladesh

Abstract: This study provides a comprehensive post-construction evaluation of the Kishoreganj-Karimganj-Chamraghat Highway, including the Choyna-Jashadal-Chowddashat Bazar Link Road, a key project implemented by Bangladesh’s Roads and Highways Department (RHD) to enhance regional connectivity and socio-economic development. Funded through government grants, the project faced challenges such as land acquisition delays and disruptions caused by the pandemic, yet demonstrated resilience through adaptive management strategies. The evaluation compares the original and revised design specifications using both RHD and American Association of State Highway and Transportation Officials (AASHTO) standards for rigid and flexible pavements. Utilizing a mixed-methods approach, the study integrates field survey data, stakeholder feedback, and design analysis to assess the project’s performance. Significant findings include adjustments in pavement thickness to meet international standards, enhancing the highway’s durability. Financial assessments reveal an 18% cost increase due to design modifications and regulatory compliance. Despite these challenges, the project exemplifies a commitment to sustainable infrastructure development, aligning with global best practices. The study also highlights technical and environmental issues encountered during and after construction, leading to three project revisions. The discrepancies between design plans and actual construction outcomes underline planning and execution deficiencies that need addressing in future rural highway projects. Recommendations include improving planning processes, enhancing stakeholder communication, and ensuring periodic infrastructure reassessments to address evolving traffic demands and environmental conditions. By providing a detailed assessment of road conditions, signage, lighting, and drainage systems, the study identifies sections requiring immediate maintenance or rehabilitation. The lessons learned from this highway project offer valuable guidance for similar rural infrastructure initiatives worldwide, ensuring long-term benefits for both the economy and local communities.
