They just haven't added the siding in where the truss connects yet. At this point we can tell that there's nothing under the truss, it's simply a big truss designed for a lot of big people on top.
I just can't believe we've made it this long without hardly any indication of how the track will be laid out other than the speculation on the beginning. The tiny bit of track that they have put up is such a tease. Usually you can try to make guesses by connecting the footers, but I haven't even tried with this thing.
That's what makes this announcement so sweet - we know so much and yet so little. It might be one of the last times that we see a ride come this far along in construction and still don't know quite what it will be.
