Chaussee is an historic term used in German-speaking countries for early, metalled, rural highways, designed by road engineers, as opposed to the hitherto, traditional, unpaved country roads. The term is no longer used in modern road construction in Western Europe, but survives in road names and is used by historians. In Eastern Europe and the post-Soviet states it remains a generic term for a common paved highway outside of built-up areas, but they may transition into prospekts within towns and cities.
