Thank you, Andy!
Yes, there is a lot packed into a small space. It stopped raining and was reasonable to work outside the last few days, plus I had other jobs and a couple doctor appointments, so I didn't get much more done. I am actually to the place I could put the double track bridge in place. I will have to remove the one of the mounts for one hinge and a guide on the opposite end where the bridge end drops into place. Since I'll be doing more outside, I don't want to take the bridge our for an extended period of time. I'll work on some other things when I get a little time for now.
