Mapping curved and twisted surface

Please I need help!
How to mapping wood floor texture to a bridge that’s not flat.
I attached photos
I am using V-ray for material


The simplest thing(well on this shape, often that’s not simple at at all,) is to model it as a sweep or something so that the layout of the surface coincides with the flow of the texture…which it looks like that partially does, but it needs some adjustment, then it’s just a matter of adjusting the texture tiling.

Oh, FYI, there’s no such thing as a “Corporate” Rhino version.

Thank you so much
