Street network design according to topography

Hi everyone,
I have this problem, I defined a scheme like the one in photo 1 for the installation of a new urban center,
What I want to achieve is to adapt this scheme to the toography of the place, and to be able to modify the slope of the axes with sliders.
Each connection must have a specific width.
Does anyone have any idea how I could do it?
I attach the topography file.
