CNN/FOX correspondents...From what city are they reporting when I see two arches/spheres in the background?

News correpondents on CNN and FOX often stand in front of an identifying landmark in the city from which they are reporting. It's always extremely obvious when they have the Space Needle in the background that they are reporting from Seattle; likewise with the St. Louis Arch.



Recently, though, I seen a number of reporters standing in front of a background of a couple of structures that look like (for lack of a better description) chicken wishbones. They are arches or spires. The one on the left looks like an upside down wishbone. The one on the right is a similar shape but more "filled in."



Any idea what city this is, and what those structures are?CNN/FOX correspondents...From what city are they reporting when I see two arches/spheres in the background?
If it looks like this, it's Boston. The wishbones are the struts of the new Zakim Bridge.
