斜張歩道橋：単塔と扇形ケーブルのバランス

Design a pedestrian bridge in the manner of Santiago Calatrava, where a single inclined white pylon leans back against a fan of stay cables and counterbalances an asymmetric curved deck. Compose a tall raked mast with no back-stays to the ground on one side, cables splaying in a precise fan, a curving deck with a glass walkway panel, slender steel balustrades, still river water below reflecting the whole geometry, clear dusk light with the mast lit from below, low three-quarter view from the bank, 24mm lens, architectural photography, ultra photorealistic, 8K
