I have a T-Intersection created for my proposed secondary road leading into an existing main road. As you can see in the image i have attached.
Not sure if there is a way to do this but i want to hide my intersection from the bold yellow line onward because that is where construction ends and i only want to create my final surface to the edge of the existing main road.
I am going to go out on a limb here and assume that you are not using AutoCAD Architecture to produce what you are showing in your image. If you are using Civil 3D, you will get a better response by reposting your question in the AutoCAD Civil 3D General Discussion group.
