This is a easy to build bridge idea that I make about 7 years ago, good for going over a river or lake.
It's 4' long and 4" high at track level.
I used a 2 7/8" hole saw to cut the openings then ripped the board below the center of the hole.
I used 3" PVC Thin Wall pipe cut to length and cut down the middle. Then sprayed the inside and out side lip black. The pieces held themselves in place with spring action.
It's wide enough for two tracks.
It worked out well for what I needed.
