Maintenance, Retrofit, and Replacement of Pedestrian Suspension Bridges in Pakistan

<p>This paper explores the complexities involved in the maintenance, retrofit, and replacement of pedestrian suspension bridges in Pakistan’s northern mountainous regions. These projects present unique design and construction challenges including significant natural hazards, limited information on existing structural and geotechnical conditions along with difficult site constraints. Approaches to manage these unique challenges and risks are presented, concluding with a discussion on resilience in the face of the extreme weather events, and the impact of the 2022 floods on bridges on these regions.</p>
