トラス・スカイブリッジ：露出構造と交差のリズム

Show a pedestrian bridge built as an exposed steel truss, with the structure forming the enclosure. Render a through-truss where the walkway passes between two vertical trusses rising to shoulder height and above, their diagonal web members creating a repeating triangular rhythm along the whole span. Detail the members as slim rectangular hollow sections with clean welded joints and gusset plates, painted a single dark charcoal so the geometry reads as pattern. Show cross-bracing overhead between the two trusses at intervals, leaving the sky open between them rather than roofing the bridge. Detail the deck as an open steel grating over the road section so light and rain pass through, changing to solid epoxy surfacing at the approaches. Show the parapet infill as a fine stainless mesh fixed inside the truss plane. Include the shadows the truss casts on the deck as a strong repeating diagonal pattern. Show clear morning sun raking along the span. Photorealistic, graphic, dark steel against sky, eye-level view along the walkway.
