This has an interesting juxtaposition of the organised and the disorganised, in both the progression within the bridge's boards and the surroundings re the bridge itself; however I think your tonality has strayed so far into the pure black/white world, with few greys, that any sense of photographic representation is almost lost. The composition is slightly at odds with your title too - it's the tangle of bushes rather than the darkness that seems the reference point of the motion indicated by the bridge.
Nice "old" feeling. A little to dark and contrasty for me for this contest, though I could see this being sold as a black and white fine art print. Good job.
