Actually Steve, if you go by the "50 Year Old Rule" that I have used as a guideline for what is considered historic... then this one would qualify.

As for it's merit on appearance... I'm gonna pass on that one!

And before everyone fills up the comments. I know it's not historic or notable. I was there, I had a camera, it's still an impressive structure. Someday when they're building bridges out of carbon fiber and some alloy that has yet to be discovered this "will" be a historic bridge.
