Making A curvature in Bridge Body between Piers

Hello All
I managed to model this Bridge body ( Figure #1)
But I want to make a curvature between every two Piers like Figure #2

There is a parameter called Height of each edge of the element.
I just do not know where to start.

Hi @mr.3ezzo,

Creating objects with arcs is probably completely different how you created your first rectangular bridge.
Could you elaborate more on how you created your first bridge, (maybe share some graphs/ dyn files).
