A38

A38 is a designation used in various national road networks to label long-distance routes. In common usage in English-language contexts, it most often refers to an important road in the United Kingdom.

In the United Kingdom the A38 is a major trunk road that runs roughly from Bodmin in Cornwall to Mansfield in Nottinghamshire, forming a key north–south corridor across the southwest and midlands. The route passes through rural landscapes and urban centers and is maintained by National Highways. The road comprises sections that are dual carriageway and others that remain single carriageway, with upgrades completed over the years to improve safety, capacity, and travel times. It supports freight and commuter traffic and intersects with several motorways and major A-roads at various points.

A38 is also used in other countries to designate significant highways, though the exact alignment and status differ by national system. Because road numbering schemes vary, the A38 designation in one country does not imply a direct relation to the UK route.

Historically the A38 has seen periods of reconstruction, widening projects, and occasional closures due to maintenance or incidents. Contemporary planning continues to emphasize reliability, resilience, and integration with regional transport networks.
