Freeway intersections

Freeway intersections and exits, should be labelled with a landmark. The landmark should be kept tight to the road system to ensure a tidy transfer to the client. The landmark should be named with the number and the name of the intersection.
Type is: "Junction/Interchange".

Example: "17 Frick"

  • Frick.png

Example: "8 Liestal"

  • Augst.png
