The Expressway contains sixteen road parts to lay-out a nice flexible road over 101 inch length. The shape of the parts are straight, curved and crossed with different road markings on both sides to offer lots of variation in design of the road. The high grade, child safe material is tough, unbreakable and yet flexible so that obstacles can be taken and the roads can be laid out on almost any surface... indoors and out! This is one of our bestselling products. Cars are not included in the sets.
