Modeler's Moment - Putting a bridge against a backdrop

No outlet
So you've got a small rail bridge that you really want to use on your layout but the track is right up against the backdrop. How do you blend the road under the bridge into the backdrop while keeping it realistic? Block the road! I spotted this former bridge and road underpass yesterday in Waupaca, WI; the road used to go through under the bridge, but has since been blocked by fill material. My guess is that the bridge itself is rated for lighter trains than now run over this line and it was cheaper to just close the street and fill in under the bridge than to replace the bridge.
