Could anyone help to improve ma corridor and create a surface of finished level surrounding corridor.

I see too many problems, mostly because you design is far too complex.  You need to massively simplify your alignment and remove all these short curves.

You don't have enough surface data in some sections as your corridor barely fits over the EG.

You also have multiple areas where your grading is overlapping, this is known as a "bowtie", these all need to be fixed.

Your alignment is far too complex.  You need to simplify your road design considerably.

You have to do what's been advised. On you horizontal alignment use a tangent straight line, followed by a curve. A large curve on the bends, so you sweep around and then a straight. Increase your frequencies in your corridor on the curves. Try to do the same on the vertical alignment and use more straights than curves,
