Mind if I, Nas' assistant on this case, join with my (conspiracy) theories?
My theory bases on following evidence:
1) The bridge seen on the GT3 version of SSR11
2) The sign indicating Route 7 seen in the GT5 version of SSR5
3) Common sence (
)
But before I start, this is made assuming that SSR5 and SSR11 is to the "west" of SSR7. While that may not be true, it's my theory they are.
I also don't say I've got the scales of the tracks exactly right, but I think they show the main points of my theories.
Some useful information:
The red lines are continuations of the SSR5 and 11 main highways, assuming they go straight forever.
The yellow line is a road seen on SSR5 that runs straight (the one with the tunnel, that you run under before entering the park)
The green line is SSR5's "7" indicating road, assuming it's straight.
Before we start on the theories, a small interesting notice I made. The yellow lined road, which appears to be straight, runs from an intersection on Route 5 and appears to connect to Route 11 in the 90* righthander after the first chicane. Could this be another connecting road?
Theory 1: The "Route 7 is directly connected to SSR5" theory
This theory mainly bases on evidence 2. The road is, as far as we can see, straight, which means it's easy peasy to draw it. Assuming that this road connects to SSR7, it would have to look like this:
View attachment 84640(Assumption here is that SSR5 and the tunnel on R7 is somehow used to connect them)
or like this:

SSR5's main highway being the road that forms the first hairpin on Route 7.
But that brings another problem. The bridge on SSR11. And that's where theory 2 comes into play, the "It's all the bridge" theory.
This, obviously, builds on the bridge in SSR11. The roads connecting SSR11 and SSR5 are the same, and all I've done actually is to change the position of SSR11 and SSR5 in relation to R7:

Now, this looks a bit more like it, for 3 main reasons:
1) The bridge from SSR11 is in the right place (-ish)
2) We still have a major highway connecting to the Route 7 intersection
3) There is still the possibility that SSR5 and SSR7 is directly related
Now, you may ask, where's SSRX? My assumption is, that it's a long way out west. The only hints we have are a few cranes in the background of the final corner on SSR5 and the signs indicating an airport, which could be any, really. Therefore, I have not included it.
