Just be careful Pete when you lean on those bridges, especially when you have issues with flimsy step ladders. Here us one of my smaller bridges that is over a highway underpass.
Will have this tunnel on my layout, if I ever finish it. The first one I made out of styrene and I am so proud that Mike Danneman considers it nice enough to have on his outstanding layout. I hope this will 3D print. I have the complete tunnel (East Portal) but have to break it into two or three sections (three if I do the the last concrete blower building) so it will fit in their printers.
Okay, here's another shoofly bridge to replace the first shoofly bridge. I built this bridge to help me sort out the terrain over a small gully and establish the foundation for the trestle bents.
