I double checked and there are traffic lights at that intersection which can be seen in available Mapillary(2018) and in Bing satellite imagery(2024). Do you have a more recent verifiable source to confirm this intersection has changed? This is a standard model for these types of intersections in Utah.

I did read your proposal, but its relevance wasn't clear. What you proposed can already be described with current classifications and tags. I also could find your proposal mentioned on the forum or mailing list which is required according to the Proposal Process guidelines here: https://wiki.openstreetmap.org/wiki/Proposal_process. If you really think your proposal has merit you need to follow the guidelines on that page so the community can help you improve it and vote on it.
