The RFK Bridge (nee, Triboro):
I particularly like this shot:
The Hell's Gate Bridge:
And this shot is a favorite:
The Hell's Gate Bridge is particularly massive. Each of its trusses is huge, and they make the RFK bridge look almost delicate in comparison. In the second photo from the bottom, I wanted to show the scale of the bridge, with the light post in the frame for comparison.
The last photo is a favorite shot of Georgia's, as she says it looks like the bridge is cracking.
This shot, from Wikipedia, shows how close the two bridges are, RFK on the left and Hell's Gate on the right:
