Carl, I'm not trying to be difficult, but the bridge tracks in every design posted so far appear to be 4.75" when I add the center line to the display and measure in SCARM. Since the tracks on the Atlas bridge are indeed 4.5" and the length is 40", I'm not sure why they were set to 4.75" and why cut pieces were used rather than two sets of 30" and 10" to make the 40" span.
There is also a thread here that suggests a 10" lead should be added to both sides for clearance of some passenger cars, but there are also photos showing O54 and O63 curves going right up to the bridge. While that part is covered by the straights and switch, so it's really a non-issue in this case, I think the bridge tracks should be corrected and made a Group so they don't accidentally get moved. I'd add the first tracks on both sides of the bridge, including the lead switch for the yard, to the Group just to make sure everything stays in sync. Everything else would then flow from the Bridge Group with the goal of retaining the 4.5" spacing all the way around and through the crossovers regardless of where those are eventually placed. I thought the switches without the fitter were correct, but we were playing off the bridge spacing and I believe it's wrong.
Also, when I look at the Eye-Candy file, I see several tracks that can't join, so I don't know if that was an attempt to repair the joints that broke or what. The only one I can't get to stay connected is the one I circled in Red.

Depending on how you have SCARM set, I guess the connections could break, though as I said, I've only seen that here with the connections between a curve and straight. That said, I try not to put cut pieces, or even small fitters, by the curve anyway. When I need small fitters, I try to group them in the center of straight sections.
I, too, am sorry for your loss. This is not that important that you have to try to find time to comment, so tale care of what you have to and we'll get back to this when you have time again. Mike and I won't go too far with this until your situation settles down.
Mike, I'm not sure why you like the Eye-Candy version over the later version I posted. The only difference between them is that I added the crossovers like Carl mentioned and posted a wider 3D photo. I copied Carl's river, road and bridge setup and added it to mine. I also was able to connect all but the 1 joint on the left side of the circle. Unfortunately, that was before we found the Atlas bridge spacing is incorrect. Since Carl might be out of pocket for a bit dealing with his issues, I'm going to go ahead and fix mine the way I suggested above and see if I can't get the spacing and joints correct. I'll post it and Carl can take a look when he finds some time again.
