Here's a quick shot of part of my new road system. I made about ten 1' straight sections, two curves, a fork, and a "T" section. They are 4" wide, and allow for 3 men in the road with 1/2" or so of grass on either side. All are interchangeable and fit together in a a variety of configurations. The pieces are made from 1/8" wood, beveled on the edge, covered in sand and kitty litter, and lined with flock, static grass, and clump foilage.
