The Market Street Bridge

You hear "They don't build them like that anymore!" and it's true - they don't. It's grand and imposing and impressive and in my opinion, a work of art.  Nothing is done on this scale now. Not feasible, I know.  Thank goodness we had a burst of prosperity back in the day, giving us this structure (and many more, around town).
Thankfully, we also have the Veteran's Memorial Bridge, which is basically just ugly but a great place to stand for a shot at the above.
