The "canyon" is approx. 18" railhead to bottom. I have envisioned scratchbuilding a wooden trestle but it wouldn't look right with the Mainline CP locos I will be running(my opionion lol).
I am looking at using another Lionel # 231 truss bridge(upside down this time) to give it that heavy
mainline look at this time. If I can muster up some energy after work I will continue on my quest...
Mark, I was checking out your layout thread and I have an idea for your track plan
