Remember I’ve got that big hole in the middle. I’m going to go with option 3. But remember I run the pantographs on Gg1 and Acela so that’s why I’ll be squeezing it. 

Dave’s right I only have 2 auto switches o-48s in left hand left. Currently I have the switch on the bottom going into the other switch with 2 dead ends not going over any track. Will take a photo tomorrow for you guys.

Robert, something's not adding up. I see extra 10" tracks in each of the ovals, so what you've laid out appears to differ somewhat from the photos we've been working with. Assuming that's the case, here's the best you can do using Option 3. It will require you to add a support as shown. If that goes too close to the gold track, you'll need to adjust the width by replacing 10" tracks with 5", etc., and move the support.

The Atlas 40" bridge is too long with the curves leading into it, but something in the 30" range would fit.

Here are some samples that I found, so I can't vouch for the accuracy. The first is an under arch style, the middle is supposed to be a Lionel double truss bridge and the third is supposed to be an Atlas single truss bridge. Here's a link to Lionel's single truss bridge that is 26 1/8" long, 7 1/2" wide and 12 1/2" tall. Obviously, you'll need to figure out how to support it.

I can assume it’s compatible with the trestle set. The only specs I find says the underbridge clearance is 5 3/4” and the trestle rise 6 1/2”. Obviously the track sits on the bridge structure, so they should line up with the tracks on the trestle.
