How to use

See highway=motorway_link for general information about "How to Map" the motorway and the motorway link.

At the junction point (node) where the motorway_link splits from the motorway and add the highway=motorway_junction tag to it.

Junction naming

One can use name=* to show the name of a junction; please use source:name=* to provide a citation for the name of any junction—source:name=traffic_sign, source:name=local_knowledge, etc. If a junction is numbered (like almost all motorway junctions), the number of the junction can be included using the ref=* tag.

Destinations

exit_to=* should be used to detail the destinations where the junction exits to—for example, if signage states a road leads to Anytown on the A1000… exit_to=Anytown A1000; if multiple destinations are shown on signage, tag them with semicolons: for example, exit_to=Anytown A1000; Elsewhere A1001; Anyvillage; note that Anyvillage doesn't have a ref number.

Another way to record the actual signs, proposed earlier is at Relation:destination_sign.

Uses

Apart from use in motorways, there is a suggestion that we could use motorway_junction in primary or even secondary roads (see this thread) for indicate interchange of roads. For example, in this secondary highway.
