After doing some research, I've started to draw out scale plans for the trestle bridge that will enable the logging branch line to cross a 250 foot span over the mainlines in the area of "Shallow Canyon".  This bridge will be entirely scratch built using bass wood with modified Micro Trains flex track incorporated into the bridge's deck.

With the modules all temporarily mounted together, I'm now focusing on adding the foundations for the tracks runs.  This is where it gets interesting as I can play around a bit with the layout design before finalizing the routes by glueing down the foam bases.
