context_page_description: A highway location marker is the modern-day equivalent of a milestone. Unlike traditional milestones, however, which were originally carved from stone and sited at one-mile intervals, modern highway location markers are made from a variety of materials and are almost invariably spaced at intervals of a kilometre or a fraction thereof. In some countries they may be known as driver location signs, milestones or kilometre stones.
context_section_description: Roads often have two or more numbers.  This can happen where two highway designations run concurrently, or share the same piece of road for part of their route or when the same road is numbered by two different authorities.  Certain road authories prefer to only display a single route identifier on their roads, but others display both route identifiers on their roads.
  A common example of roads numbering by different authorities is the numbering of the European routes—all such routes have local numbers in addition to the "E number" allocated by the United Nations Economic Commission for Europe (UNECE), though is some cases, such as Sweden, the local route numbers have been changed to match the "E" numbers.
  The picture shows a typical route marker in Europe (in this case Belgium) where both the European route number and the national number are displayed on the same location marker.  The style of the route marker, apart from the green E-route indicator, is specific to the country concerned.
