How to Create Roads that Curve at the Edges

I’m using the Spline tool to create realistic roads. I want to create a road that has slightly curved edges or make the road slightly higher at the center (in real life, these help with water drainage on roads). Does anyone know if this can be done within the free spline tool (like how you can change the thickness or width of road)? And if so, can the degree of the slope be customizable? Thanks!

Why not just modify mesh in DCC app? Any reasons for procedural solution?

to have it higher in the center you will need to modify your mesh in a modeling program. as for making the mesh wider or thicker in general im sure you could do some scaling. another drainage solution would be to have the road rotated/banked slightly in one direction which is also common to see. i believe there was a video tutorial by epic that incorporated banking of the road but since they changed the website youd have to look on their youtube channel.

Ideally I would want control over how sloped the surface is and be able to modify this degree for different roads
