5. Conclusions The analysis of the Fisculco Bridge within the broader context of Bolivia's transportation infrastructure reveals both significant challenges and opportunities for modernizing bridge risk assessment and management practices. Bolivia’s complex topography, aging bridge stock, exposure to seismic risk, and absence of a unified national bri dge management system underscore the urgent need for regulatory reform and technical innovation. The case study of the Fisculco Bridge demonstrates the potential of integrating International best practices, particularly those derived from the Italian Guidelines 2020 framework, into the Bolivian context. This includes structured risk-based classification, seismic vulnerability analysis, and multi-level monitoring approaches that are currently lacking in national practice. The recently enacted Bolivian seismi c code NBDS‑2023 provides a promising foundation for incorporating these methodologies and aligning local design strategies with probabilistic hazard data and performance-based evaluation criteria. The crowd-based inspection confirms that publicly sourced data — derived from social media, satellite imagery, and open mapping platforms — can enhance infrastructure transparency, support preliminary assessments, and complement official datasets. While such sources are valuable for capturing general geometry, visibility, and social usage, they fall short in delivering high-resolution diagnostic data needed for structural health evaluations. Nevertheless, their integration into a broader bridge monitoring ecosystem could strengthen participatory governance and early-warning capabilities. The combination of seismic vulnerability assessment, public data analysis, and structured monitoring — anchored in internationally validated methodologies — offers a path forward for Bolivia to transition from reactive to preventive infrastructure management. The Fisculco Bridge serves not only as a strategic transport asset but also as a pilot for the broader adoption of modern bridge evaluation and risk mitigation practices throughout the national network.
