What is the best method for incorporating breaklines into my TIN model?

I have surveyed points, such as road kerbs which I have strung together to create a line shapefile. 
How can I use this as a breakline in my TIN model?

So you are digitizing the lines by snapping between known control points?  Is that correct?  Well, I would recommend the break lines for the crown of the road, edges, and the curb and gutter to create a better surface for contouring.  I am not sure if I would just start creating the lines by snapping any control points together.  To force the surface to model that as a line, be sure to specify the input as a hard line when creating the TIN or editing it.
