Fixing intersection of bike path

Any ideas on how to make this connection smoother between these two curves only using grasshopper?

Is there a way to nicely join the ramp level, and remove these arms:

Senza il disegno originale è difficile.
Si può fare così tenendo presente che l’ultimo pezzo della curva deve essere in piano.

ah i see, only works for intersecting curves which are on the same plane, I was wondering if it could work another way where the curves dont necesarily share the same z?
