A42

A42 is a designation used in multiple, unrelated contexts. It does not refer to a single object, but to a label applied in different domains, including road networks, manufacturing, and cataloging. The meaning of A42 depends entirely on the domain and country.

In road networks, the A prefix followed by a number is commonly used to denote primary routes in several national systems. The A42 designation can refer to different roads in different countries, typically maintained by national or regional authorities. The exact characteristics of each A42 route—such as whether it is a motorway, its length, toll status, and its endpoints—vary and may change over time due to construction, renaming, or reclassification.

Beyond transportation, A42 also appears as a model or part number in consumer products and machinery, and as a code in catalogs, datasets, or standards. In these uses, the same designation can be assigned independently of any road designation, reflecting organizational labeling practices rather than a shared infrastructure.

Because A42 spans multiple domains, precise information requires context. When encountering A42, consult domain- or country-specific sources to determine which particular entry is being referenced and to obtain current details on its status, location, and governance.
