To address the recurring safety hazards caused by icy surfaces and winter precipitation on the auxiliary pedestrian bridge in Zhoushi Town, this design intervention introduces a lightweight, high-performance weather-shielding system. The architectural response prioritizes a minimal structural footprint, utilizing a sophisticated light-steel framework that seamlessly integrates with the existing bridge anatomy without imposing significant dead load. The primary enclosure features a translucent ETFE (Ethylene Tetrafluoroethylene) tensioned membrane structure, chosen for its exceptional strength-to-weight ratio and self-cleaning properties. This semi-transparent skin creates a diffused, ethereal light quality beneath the canopy, ensuring a bright and safe passage for pedestrians while maintaining a visual lightness that complements the bridge's red arch. By balancing functional durability with an elegant, airy aesthetic, the new canopy effectively prevents ice accumulation and enhances the public infrastructure's resilience, transforming a hazardous crossing into a luminous, protected urban link.
