This is a maintenance scene inside a large bridge, featuring heavy steel beams and trusses coated in light green anti-rust paint. Massive I-beams are connected by dense rows of rivets and bolts, forming a stable cross-bracing system, with metal scaffolding and wooden temporary walkways erected in certain areas. Through the gaps in the steel structure, a wide river, distant city buildings, and a clear blue sky are visible, with sunlight casting distinct shadows on the metal surfaces.
