Nice vantage point and perspective on an interesting bridge. The photo as a whole, though, seems washed out, having so many of the same tones. Try fiddling with the contrast levels to provide more dynamic tones.
You're fortunate to have such a bridge available to you to photograph. I like the color contrast and pretty much everything about this photo. I also like those signs on the side of the bridge showing the 11'5" height in an area where there really shouldn't be any vehicles in the first place.
Really nice colours here. I like the orange signs and the grays on the bridge with the lighter stains on the rails. I like the way you captured the inside detail of the bridge. Really good shot.
