Fort Pitt Bridge
Fort Pitt Bridge is the one closer to the vantage point on the left side of the photo. I don't know if the one further afield is part of Fort Pitt Bridge or not.
Pittsburgh is surrounded by rivers and hills, and numerous bridges are needed to allow seamless movement of people and goods.
My friends and I didn't spend much time in Pittsburgh at all. I hope to return to Pittsburgh for a proper visit in a few years.
If you like what you're seeing, I recommend you to take a look of my friend Brandon's photoset of the beautiful city via this link:
