I second the bridge arrangement! Looks fantastic! I'm sure watching trains rumble across that arrangement is a joy.
Your installation of the switch in the truss bridge is very well thought out and executed as well! I have a truss bridge across my layout's inside access as well and I'm constantly scanning when I remove the bridge to make sure I won't have a train, especially expensive Legacy locomotive(s), tumble to the floor. If I do something similar in my next layout, I'll definitely steal your idea
Using the Melrose Park Station from Menards with the N scale loop is also a great idea - it fits right in!
