You should be able to use "snapping" when creating lines in order to
have good precision. Walkthrough 2 has examples of how to change
between snapping modes. I would have a point for the different
intersections on one layer; have a second layer for the roads and
while I draw the roads I would have snapping to the point layer turned
on.
