Nope, it's not :)

Look at TFA again. Just like the photo I linked to, the motorway (interstate in this case) passes under the 2 bridges.

The local version of this (NM14 & I25) has the interstate passing over on a single bridge, the double diamond is on the "ground level".

You're right; I hadn't scrolled down to the wide-view shot. I stand corrected.
