This bridge is fairly difficult to shoot at night. I tried again, and learned several things. The lights that illuminate the cables aren't visible until the sky is quite dark, so it's almost a waste of time to shoot with a slightly bright sky. The bridge is just a silhouette and doesn't have the grandeurt that the lighted cables provide. And when the sky is correct the brightness is fading so fast that it's impossible to shoot an entire pano at the same exposure. (Perhaps in the summer when the light change is slower.) Also, when it's dark enough some of the surrounding lights are quite bright, and the exposure needed for the rest of the shot means that those lights blow out quite severely.
On the other hand I noticed that the sun sets almost directly behind the bridge from this shooting location, so it may be worthy of another attempt if I can be lucky enough to get a good sunset.
For now, though, this is the best I can do, and it's not that much better than my last attempt. But I'm happy that this is a 2-row pano, so the resulting file is 3450x11200, which means that I could print it 12x36 for a decent-sized 3:1 pano.
