Roads outlined/highlighted in red?

Just a simple question here as I get familiar with using OSM & Potlatch… Why are some of the roads outlined/highlighted in red?

I’ve looked all over to an answer to this one to no avail.

Thanks!

There are two kind of ways which appear red in potlatch:

  1. highway=primary: The color depends on the type of street. highway=motorway for example are blue
  2. deleted ways: If you hit “u” potlatch will display all deleted ways in the current view in red. You can undelet them if you select one of them and click on the little lock beside the way-id in the lower left corner.

Also, if you have the “Highlight unnamed roads” option on, roads without names stored are drawn with red borders.
