When I look at a bridge, I think of travel, of engineering, of safety, and of history. Even new bridges change history as soon as they can be used.
In this photo, the arches are reflecting and making a round shape. That's always fun. There is also roundness in the tree to the right, and in its reflection in the water. The bank of the river has a rounded edge, and is covered with rounded pebbles.
Others, seeing that, might be thinking of what birds live around there, or other wildlife. If it's someone familiar with the area, they will know where the road goes, maybe who owns the land, and who used to own it before that.
Kids, seeing it, might wonder first "Could we get IN that water?" Wild swimmers (people who like to swim in naturally occurring waters) probably had that thought before any other.
Any scene is many things. The knowledge and perspective of each viewer is different. People spot different things and make their own connections.
