The presence of road junction as such (crossroads, T intersection, Y intersection, any other type…).

When not to use

Junctions on motorways (or similar) serve for orientation and transport at great distances (and not for orientation in the local area). Use highway=motorway_junction for these cases, and not junction=yes.

How to use on a node

Simple crossroads

Junction yes example 1.png

Tagging the node that connects the two ways.

Simple 3-way intersections (Y intersection, T intersection)

Junction yes example 4.png

Tagging the node that connects the two ways.


If appropriate, you can optionally add highway=traffic_signals on the same node. If you also add a name=* tag, it might to better/clearer to use highway=traffic_signals on the connecting node and draw the junction=yes element as an area – so it is unambiguous where the name belongs to.

How to use on an area

Example id junction area.png

Draw an area (a closed way or a multipolygon) around the junction area as found on the ground. The area is tagged with junction=yes. The area shares nodes with the incoming and outgoing ways, so routing/turn-to-turn navigation engines can determine which ways are concerned. To define clearly what belongs to the area and what does not belong to the area, we require for each shared node (shared between the area and the incoming/outgoing highways)

  • that it shall not have any tags itself.
  • that it is shared between the area and only one highway, not multiple highways.

Usage examples

  • In some countries (Korea…), people orient themselves in the local area using the names of road junctions rather than the names of streets. While street names may also exist, they are less important for orientation. See “Named spots instead of street names” for details. In other countries (Poland…) some big junctions (usually interchanges) are named. A rendering engine should render the name of the junction. In these countries, you use junction=yes together with name=*.
  • This tag can give information about the extension of a junction. This can be useful for routing/turn-to-turn navigation engines. Because they know now what exactly belongs to a junction, they could count them and say for example “Go to the left at the second junction.” In countries like Korea, routing/turn-to-turn navigation engines could say things like “Go to the right in the XYZ junction.”
