Hrm, this was taken at Hill Street Carpark, if I remember the name correctly. It's actually taken from the side of a building parallel to the river banks that you see in the photo (I'm sure you can picture if you're familiar with the place). Actually, I deliberately darkened that corner, as there was a tree there - if you save the photo and lift up the shadows you'd spot it in a jiffy.. Minimizing presence of the "dark water" would require moving further away from the road, I guess. I did take a few shots, but the angle of the bridge was not optimal, i.e. it would become more parallel to the horizontals. Given this scenario and the constraints - would you have any suggestion on how to overcome this?
