I have made the correct changes to the map based on these standards. According to CDOT, Chambers Rd, Hampten Ave, and part of Quincy Ave are listed as level 3 - Primary Arterial.
If you refer to this CDOT site, it can give you more information on the classification type under the FUNCCLASSID column: https://data-cdot.opendata.arcgis.com/datasets/cdot::major-roads-1/explore?location=39.638445%2C-104.777780%2C13.71

I would recommend using this dataset when considering classification here on OSM.

I will go ahead and correct the piece of Quincy Avenue that I incorrectly classified based on these standards.

Sounds good. I will go ahead and make the corrections. As for applying globally, every state has its own guidelines so it defiantly can be confusing. Thanks for letting me know what the local standard is.

Alright then, what are your suggested ‘next steps’?

That is a good question. This was a while ago so I only found this listing without the name: https://www.apartments.com/1611-arapahoe-st-golden-co/01gv3d2/

If you see fit, you are welcome to make a correction to this building.

I was just naming the roadway per county records. I was unable to find documentation of the state's specific tagging standards.

Hi Chacha, I was able to read the wiki and I have removed the "is_in" tag. Thanks for letting me know of this.

I went ahead and created a new changeset: changeset/86267747

Hey Chacha, I am going to redo this intersection for you to look at, to be a bit more clearer. I get that it doesn't make sense.

Hey Chacha, Thanks for letting me know how to correct these. I will keep it in mind when I correct way names. Thanks for all your help.

Just wanted to let you know that in your recent changeset, the way (605513683) was missing the highway - motorway was removed. I have fixed this and no further action is required.

Oh, I know what you mean. I am correcting it right now. Thanks for letting me know.
