|A nice find indeed.
Scott, you're right about the location.
Jose, I think you're about the legend too.
With the help of google streetview / maps I've got some photo's from a different point of view.
You can see that the upper bridge has a bigger beam in the middle, that was not necessary if it was designed like it is now.
Personaly I wonder how they deal with temperature expansion.
There are some bearing blocks between the two bridges but I can't see them under the lower bridge
And why did they use ballast on the bridge?
The extra weight makes that the construction has to be extra heavy too.
There other solutions for that.
Here are the photo's from google:
