This new edition spiral bound caries all the features of the normally bound Road Atlas and is the same size but, because of the extra strain that the spiral binding causes, the paperweight has been nearly doubled and the laminated cardboard cover is also doubled in thickness. This has resulted in a substantial book that is durable and able to stand up to the tough treatment we all know the Road Atlas gets in the vehicle. Identical to the Australia Road Atlas but in a spiral bound version to enable you to leave the atlas open to a page without damaging the spine.
