Aroads

Aroads is a term commonly used to describe the main arterial roads designated with the letter A in the road classification systems used in the United Kingdom and some other regions. These roads are typically strategic connectors that carry longer-distance and regional traffic, sitting below the national motorway network in the overall hierarchy.

The A-road network is divided into primary and non-primary routes. Primary A roads are intended to support longer journeys and inter-regional travel, and many of these routes feature higher-capacity alignments such as dual carriageways or upgraded sections. Non-primary A roads serve more local or regional traffic, providing important connections between towns and local centers. Maintenance and development of A roads are usually the responsibility of local highway authorities, with national policy and funding sometimes guiding major upgrades or bypass projects.

Historically, the A-road system was established in the early 20th century as part of an effort to classify and organize the road network. Over time, routes have been reclassified, upgraded, or converted as traffic patterns and transport priorities have evolved. Notable examples of well-known A roads include the A1, which runs from London to Edinburgh; the A40, extending from London toward the west; and the A5, connecting London to the northwest. Similar A-road designations exist in other jurisdictions that adopted comparable naming schemes.

In contemporary transport planning, A roads continue to be a focus for capacity improvements, safety enhancements, bypass projects, and integration with local and national mobility objectives.
