You certainly meet the Bridges Challenge with this photograph.
This is outstanding work. Great depth and detail; It's a long DOF, good details nice prespective, excellent lighting for the tme of day, wonderful composition. It's one heck of a long walking bridge.
Focus is just fine, nice and sharp at the front,down towards the middle as you would expect.
I like the way you've got the two puddles on the wood on the right side but at the same time, they could be distracting to many viewers.
And I also like the way the wooden boards on both sides work as lines leading the eyes right towards the person walking at the end of the bridge.
You have good exposure, and you show good tones both in the wood and steel.
Excellent photography in my opinion. Keep shooting!
Fascinating bridge-- nice perspective, perfect tone! If I were doing the shot, I might have cropped out (or if not on DPC, subdued/slightly blurred in Photoshop) the reflections in the foreground. My attention is immediately drawn there, and I have to force my eyes to the rest of the shot.
