An "E-road" refers to a part of the international road network designated for long-distance travel and transport. These roads are marked with an "E" followed by a number, indicating their route. They facilitate connections between major cities and regions across different countries, promoting trade and tourism. E-roads are managed by the United Nations Economic Commission for Europe (UNECE) and are designed to meet specific standards for safety and efficiency. They often intersect with national highways and can be found in various regions, including Europe and parts of Asia.
