This is a common issue, referred to by the community as a "bow tie". The issue is the projection to the left of the alignment is larger than the radius that you have on the alingnment - thus this design really does not work.
A couple of solutions would be to

actualy sir this design is implemented at site. Contractor excavated half of workdone on this design there is no way to main my deisgn as it is
in eagle point toe in overlapped but in sections of eagle point it does not reflect but in civil 3d this problum occurs that it overlap in section view
how can adjust the design.
The cyan line in your sections is the corridor surface. The jagged area would be where the different corridor sections are crossing over each other. Change your surface style to show TIN lines in plan, and you'll see the problem more clearly.
If you're already in construction, and you have to fix this you basically have three choices - either a miter, chamfer or fillet in the area between the two white lines. There are advantages and disadvantages to each - you need to consider the cost of extra excavation, reduced width of benches etc.
You will have to create a surface within the area, using featurelines or grading and then paste it into your design.
Steve
