The road zigzags further and further upwards. You peer out of the car window and gulp as you look back. It’s a very long way down!
You are travelling over a mountain pass in the South Tyrol, Austria. It is too steep to go straight up, so the roads to the top wind backwards and forwards like a slithering snake.
Today, there are roads across all the countries of the world. Some are little more than dirt tracks, and others are six-lane or eight-lane motorways that carry heavy traffic in each direction.
Roads of some sort have existed for thousands of years. Often a road started as a rough track – the easiest route from one place to another. Over the years, the feet of people and animals wrote it down until it became a smooth, wide path. As towns grew, the paths became wider still. Some were covered with gravel, pebbles, or other materials to make them permanent roads.
