In my opinion instant road is a little crude, not very customizeable and also expensive. If you are willing to ‘study’ a bit I would highly recomend profile builder. It does not have ready made roads and it has a -comparatively- steep learning curve but once you get the hang of it you can create anything you want -from handrails to roads to entire house-rows with the click of a button.
I attach an assembly of of a simple road. (it can only be used with profile builder)

Thank you for your opinion. I have the Profile builder…
Could you suggest me a tutorial how to make the curve markings ?

Found this video

Good! you found it yourself!
I don’t know how well you know profile builder but I would suggest you invest in learning it well. (using sub-assemblies and all). It is probably the most versatile tool for design in sketchup.

Yeah it’s a great tool (once you get the hang of it!)
