Carriageway vs. Highway: What's the Difference?
Edited by Aimie Carlson || By Janet White || Updated on November 30, 2023
A carriageway is one side or part of a road that carries traffic in a single direction, while a highway is a main road, especially one connecting major towns or cities.
Key Differences
A carriageway specifically refers to a single part of a road where vehicles travel in one direction, often part of a larger road system. In contrast, a highway is a broader term for any major public road, typically connecting cities and towns.
Carriageways are often seen as components of highways or dual carriageways, where each side of the road is a separate carriageway. Meanwhile, highways encompass a variety of road types, including freeways, motorways, and major arterial roads.
In terms of design, a carriageway can be a part of urban streets or rural roads, designated for a specific flow of traffic. Highways, on the other hand, are designed for higher speed travel and longer distances, often with multiple lanes and limited access points.
Maintenance and regulation of carriageways depend on their location and the type of road they are part of. Highways, especially those connecting major regions, are typically maintained by higher levels of government and subject to strict regulations.
Carriageways play a crucial role in traffic management, especially in areas with heavy traffic, directing the flow efficiently. Highways are vital for transportation infrastructure, facilitating trade, travel, and connectivity between distant locations.
