Chris, you may be too young to remember Look Magazine and Life Magazine, but they were very important in their time for the photos they included between their covers. I think you have a picture here that could have graced the cover of either.
My one caveat (I do not mean to sound like Les) is that I may have been tempted to lightened it a smudge. I know, regardless if it was lighter or not, I would love to call it my own.
Definitely the best of your bridge shots. I agree with John about lightening it a little bit, but otherwise great perspective/focus/contrast/composition.
