Historic roads (or historic trails in the US and Canada) are paths or routes that have historical importance due to their use over a period of time. Examples exist from prehistoric times until the early 20th century. They include ancient trackways, long-lasting roads, important trade routes, and migration trails. Many historic routes, such as the Silk Road, the Amber Road, and the Royal Road of the Persian Empire, covered great distances and their impact on human settlements remain today.
The Post Track, a prehistoric causeway in the valley of the River Brue in the Somerset Levels, England, is one of the oldest known constructed trackways and dates from around 3800 BCE. The world's oldest known paved road was constructed in Egypt some time between 2600 and 2200 BC.
