Don't worry about taking over the threat, I really love your ideas and it teaches me a lot the more you throw in your creativity. I love both the ideas, though with the crop I do feel like there is no focus, like my eyes are looking for a point that is in focus, but keep being drawn to other points that look/feel out of focus. Is that
I'm not sure of your experience level, so if I say something you already know then forgive me. I guess the first question is "What was your intended focal point?" when you snapped the shot. It's far easier to compose in camera with an idea in mind, rather than try to make something post. A good read on composition is

In any composition I've learned to "simplify" the scene, to break it into it's parts rather than be overcome by the whole. In your OP the leading lines of the bridge are strong elements, but they don't have an equally strong intended focal point. When I converted to a B&W image and adjusted, it decreased the effect of the extraneous buildings/structures on either side of the bridge, heightening the dominance of the bridge and making building at the end appear to recede. The image was "simplified" and the bridge became the focal point. In the tighter crop by
@Cody'sCaptures the deletion of the buildings/structures on either side changed the image again, because you're losing reference points. The bridge looms forward, but so does the building at the end. However, the tracks in the foreground become more dominant. You can capitalize on that by changing the crop to get rid of the sky like this. Without the sky as reference, the building at the back loses it's prominence.
If you have the raw file you could probably bring out more detail on those tire tracks. Again the point is learn to seek out the intent of your shot in the viewfinder and you won't struggle in post. I went through a period when I was fascinated with editing post. It was fun, it was all new, now it's a pain, I'd rather be behind the camera.
