This document presents an addendum to the Environmental Impact Assessment report for the upgrade and rehabilitation of a 1 km road from Sharifabad to Kanju in Khyber Pakhtunkhwa province. The project aims to widen and improve the existing single lane road to make it accessible for all types of traffic. The assessment identifies potential environmental and social impacts during construction such as dust, noise, waste generation, and disruption to infrastructure. It also outlines mitigation measures and an environmental and social monitoring plan to minimize negative impacts. Key aspects include designating waste disposal sites, implementing dust and noise control practices, and restoring disturbed areas after construction is completed.
