A Primary Route is a road that is a part of the Primary Route Network, and is signed with green signs. The vast majority of the Primary Route Network are A-class roads, but there are some very rare examples of short lengths of B-class roads which are Primary, such as B6261. The motorway network can be considered to be a de facto part of the Primary Route Network, though it is technically not. The Primary Route Network is controlled by the Department for Transport.

Primary Routes are designed to show recommended routes between Primary Destinations, which are "places of major traffic importance", usually the most important towns and cities in an area, but occasionally other destinations such as junctions, bridges, ports or airports, or even smaller towns with important junctions within them are also Primary Destinations. Primary Routes are often (though not always) the busiest routes within a large town or city. Occasionally, a road that links two Primary Destinations is not a Primary Route (such as A4124). This is usually because a non-direct route is considered to be a better route for traffic, often because of a low bridge or some other issue that prevents the direct route being recommended for all traffic.

In the United Kingdom, Primary Routes are often confused with Trunk Roads. Generally, all Trunk Roads are also Primary Routes, but not all Primary Routes are Trunk Roads.

History

The concept of Primary Routes was created in 1964 with the Worboys report on signage, which created the modern United Kingdom signage system. They were created on order for drivers to easily identify the most important routes in area.
