LinkedIn Learning now has an OpenRoads Designer course: Civil Geometry QuickStart
You must have a LinkedIn Learning subscription (or your company does) to access.
If you do not have access to LinkedIn Learning, you can, of course, take the class from the LEARNserver.
(I'm curious and looking for feedback: who would NOT have access to our LEARNserver, but would have access to LinkedIn Learning? please add a comment or email me at email@example.com).
