Very cool Sammy. I was thinking of riding down another 5 min to PNC but it was already getting pretty dark and I wanted to get back to the Hot Metal Bridge to try and take another photo from there before all the light was gone, but didn't really make it. Plus the game was earlier in the day, so there probably would have been street cleaning and cleanup crews all around.
This is what I managed to grab at about 9:50 or so (it looks much lighter than it was), resting the camera against the girder of the bridge, but they didn't come out well: @ 12mm, ISO 2500, f6.3, 1/40, O EV.
and then a zoomed, @ISO 1600
