A Classified unnumbered road, or Class III road, is a category of road in the United Kingdom, recognised by the Department for Transport. In importance, they are between Classified Numbered roads (also known as Class II or B roads), and Unclassified roads.

Designating or de-designating a road as "classified unnumbered" requires the approval of the Secretary of State for Transport.

Suggestions for increasing the classification of roads started almost immediately after the initial allocations in 1922-23. Several London borough councils thought more roads should be classified in their areas, particularly roads that were used as bus routes. C roads began to appear as an informal set of classifications on a per-county or county borough basis during the 1940s, and while there was consideration to putting them on signs, this was abandoned. Class III roads themselves were instituted in April 1946, and from that time grants of 50% were allocated to Highway Authorities towards to costs of work on these roads[1].

It is a common misconception that roads marked on OS Landranger mapping in yellow, or those in bright yellow on newer maps are Class III roads. This is not the case, and the application of the yellow colouring refers to the physical standard of the road and not its classification.

Numbering

Although commonly referred to as C Roads, this is not always true. While the majority of Highway Authorities use the C prefix, several use other letters. For example Newport and Monmouthshire Councils use an "R" prefix, and Wolverhampton Council uses a "U" prefix, which they state stands for urban classified. Some Highway Authorities have chosen to use "Z" as an additional prefix for spurs or alternative routes off the main route, giving rise to "ZC" and "ZR" roads. Some Highway Authorities even choose to not number their Class III system at all.

There is no national system of numbering for Class III roads, which remain officially unnumbered at a national level. Each Highway Authority has their own system and therefore there can be several examples of each road number around the country - see C1 as an example. Many Highway Authorities share their numbering with a neighbouring authority, this is usually due to the numbering system being established prior to government reorganisations and boundary changes, and then the replacement authorities simply continuing to use the predecessor body's numbering. For example, there appears to be an old West Riding of Yorkshire system that is still used across the modern day metropolitan authorities. Any numbering of a Class III road should be unique within each Highway Authority; and will therefore not be unique nationally.

However, the existence of an internal number for the road within a Highway Authority does not mean that the road is a Class III road. Some authorities also choose to number some or all of their Unclassified roads network with secondary letters, often D or U.

Signage

A rare example of a C road on a road sign in Northern Ireland

As a rule, Class III numbers are not shown on signage, but they are occasionally spotted, both on permanent signs and roadworks signs. This has given rise to the SABRE term "The Great C Road Hunt"[2], as members submit sightings of road numbers on temporary (or permanent signage). Many Highway Authorities supply lists of their Class III roads online or via a Freedom of Information request, however some are less helpful, requiring a more in depth search online. As an example, a lot of Gloucestershire Council's road numbering has been gleaned from their online roadworks notices.

Roads.org.uk[3] also has a page where there are examples of visitor submitted sightings of Class III roads on signage.

Origin of name

Whilst the term classified unnumbered seems like an oxymoron, the term comes from the fact that historically the roads were classified for funding purposes, yet were not numbered at a national level.
