Creating a clean surface between a line and polyline

Grasshopper

Hi everyone,

I would like to create a surface between a line and a polyline, like in this picture below:
Both lines are always on the same Y value, and the start and end of the X value is always the same.
I managed to create the surface, but I do not need the line in the middle of the surface. It might mess up my material calculation that I would like to do later.

Is there a way to create a clean surface from the lower line, up to the upper line without cut lines? Just like in the second picture?

Thanks in advance.

Without changing your method: just use the Merge Faces component afterward will do.
