/ˌdjuːəl ˈkærɪdʒweɪ//ˌduːəl ˈkærɪdʒweɪ/

The term "dual carriageway" originated in the United Kingdom in the early 1900s to describe a type of road that has two separate carriageways for opposing traffic flows. The word "carriageway" itself is derived from the old French term "carriage" which meant a journey or a transportation. Prior to the development of dual carriageways, there were only single carriageways, where traffic from both directions shared a single lane. This arrangement led to congestion and increased travelling time, especially during peak hours. The first dual carriageway in the UK was constructed in the 1920s, and it soon became apparent that this design offered significant benefits. Dual carriageways reduced congestion, improved safety by reducing head-on collisions, and increased the speed limit due to the increased capacity. The term "dual carriageway" was officially recognized and standardized by the UK government in the 1930s, and it quickly became the preferred design for major highways and bypasses. The concept spread to other countries, including the United States, with different terminology, such as "divided highway" in the US or "divided road" in Australia. In summary, the term "dual carriageway" represents a significant innovation in road design, which has revolutionized travel and transport around the world, making it safer, faster, and more efficient for millions of drivers every year.
