Use a pencil to mark where the roadways meet. Glue the sections in place with white glue. Using a ruler and a pencil, measure and mark the middle of the road in at least two places. Take the ruler, and draw a straight line connecting the marks. Think of the roadways you travel every day, and put in crosswalks, school zones, railroad crossings, no-passing zones and other street markings where appropriate.
Authenticity is the goal.
