When you delete a curve, the straights on either side of the curve are preserved. If the straights were joined when they were created, the straights are joined at the VIP after the curve is deleted.
Note: You cannot delete a straight that has a curve attached to it. Before deleting a tangent, you must first delete the PVI and any dependent curves and tangents.
