穿越建筑年代的蜿蜒桥梁

A cinematic shot of a single, winding bridge stretching into the distance. The architecture transitions seamlessly along its length: starting as Roman stone, becoming a medieval drawbridge, then a Victorian iron truss, and finally a futuristic composite material. Each section has era-appropriate travelers and weathering. Morning mist fills the valley below, with soft light breaking through clouds. 8K.
