A detour or (British English: diversion) is a (normally temporary) route taking traffic around an area of prohibited or reduced access, such as a construction site. Detours must be followed and failure to do so may result in fines.[1] Standard operating procedure for many roads departments is to route any detour over roads within the same jurisdiction as the road with the obstructed area.[2]

On multi-lane highways (e.g. freeways, expressways, city streets, etc.), usually traffic shifts can be utilized in lieu of a detour as turn lanes can often be congested with detours.
