  Already existing features may be closed for a short time for a temporary construction (e.g. old, damaged roads getting rebuilt). Don't use construction=* to tag such short-term closures (e.g. a road closed over a weekend to replace a sewer pipe); consider using conditional restrictions instead. As OSM data is often used offline (and therefore may be several months old), only tag construction sites (particularly roads and railroads) if they are planned to be closed for at least six to nine months.
