Betonplaten straat (N)

27 individual "concrete slabs" each with a surface area of 30 x 15 mm, to construct a concrete roadway with a length of more than 58 cm.
For the designing of curves, junctions, railroad overpasses, etc.
more than 40 smaller, partial trapezoidal elements, are included.
The material is easy to handle: Glue "concrete slabs" on the plan, work out the lanes with some color and add some grass material and dandelions to finish an old concrete road.
