Status: de facto

This tag is used together with construction=* for any type of highway, including roads, tracks and paths, currently under construction.

Major road and rail construction schemes typically several years to complete. Use this key to denote active construction sites (for projects being planned, where there is little or no evidence for them on the ground, avoid tagging them or use proposed=* instead).

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.

For minor road-works (where the road in question remains open), see construction=minor

How to map

To map a highway under construction you can just draw a line (way) and tag with highway=construction and construction=*

The value of the construction=* key should be one of those defined below and indicates the type of road, track or path being built .

For example: highway=construction+construction=primary describes a highway which is under construction and its type after the construction has finished will be a highway=primary.

If you know the date at which a construction site is expected to be completed, you can tag it with opening_date=*. Additionally, you can use check_date=* to denote when you last checked/updated the values. This can be useful as large construction projects are often delayed and for some construction projects planned opening date may be unknown or complicated to obtain.

Also add:

  • bridge=yes - If the highway goes over a street or waterway.
  • tunnel=yes - If the highway goes below a street or waterway.

Values

highway=construction with any of the following values for construction=* will render on the Standard layer at zoom level 12 and above:
