Hello,
I noticed this changeset bumped the US 97 expressway section through Klamath Falls up to 'motorway'. Half of this stretch of road is undivided (some of it a two-lane road) which categorically precludes it from being tagged as a 'motorway' by US OSM standards - must be a fully access-controlled divided highway. I would encourage you to discuss with the #local-oregon channel of the OSM US Slack channel (osmus.slack.com) as I know there has been a lot of discussion about highway classification in the state there.

Thanks, 
Bradley
