Curved Displacement Roads

I've seen displacement roads/pathways like this is a few maps before, but I have no idea how to do them. HL2 Ep2's White Forest Inn actually has a better example of them than anything I can pull out of TF2, here's a screenshot:

Any idea how to do something like this? I basically need to replicate this kind of road, but copying and pasting won't do the job because mine differs in curve angle and size.

I think I've seen that tutorial before, the roads themselves are brushes, not displacements. I can do it that way but the road texture is a blend texture so I'd prefer it be a displacement.

EDIT: yeah that method isn't going to work for me. And a plus to displacements is that you don't have to adjust all the damn textures by hand.

I could make a rough version of the road out of brushes and then displace each one, but it still turns out blocky, there's not a way to smooth them that I know of.

Thanks, that works awesomely for getting the road shaped correctly, but how do you align the textures to the curve of the road?

Is top align the little T button under the justify tab? It doesn't seem to be doing anything to the selected texture when I press it.

If it's not doing anything then it already is at that alignment. It's not necessary, I just say that so when you wrap it onto the road surface it's aligned right. Either way, the point is using alt+rightclick to quickly and easily get the proper rotation.

Because it "folds" the texture around the edge/brush border and those brushes all have parallel surfaces.

If it was curved the other way (eg. the side of the arch, not the top) it would work just fine.

They told you the wrong thing.

How do I fix it then?

Also congratulations on having a post count equal to the exact width of my road in units.

I didn't tell him the wrong thing, I just didn't explain it clear enough. Here is a picture so I don't need 1000 words :p

I did this with :dispmask: and :disp3d: off to see the non-disp brush faces. You don't need to turn off 3D though, since won't matter that the curved displacement doesn't line up with the face as alt+rightclick only cares about the base faces and not the displacement location.
