I'm convinced that barrier=entrance is wrong in this case. The two wood bridges I'll have to split (in Merkaartor I guess as that's the only editor I can get to work with the USGS high res imagery). I'm still a little unsure about the roadway. Because of the use of the drainpipes it's more like ( http://www.coquillewatershed.org/Project%20photos/pages/lampa-199-culvert-03.htm), which I don't see as a bridge. I could go with tunnel=yes on the "ditch", but it's really not a ditch at all at the point it passes under the road. Also, because the roadway is linear, splitting the ditch doesn't really get the geometry right, it leaves a gap. Honestly, I don't see how the road situation isn't a case of barrier=entrance. The ditch stops for a little bit where the road crosses it. Under the road is not a ditch, but a drainpipe. barrier=entrance + drainpipe=yes? http://wiki.openstreetmap.org/wiki/Image:Sallyport.jpg That's mapped as a junction, not a bridge (barrier=wall, bridge=yes?), and it's pretty much the same thing (only, underground instead of over ground). barrier=drainpipe (as an "access node"), access=yes?
