I wouldn't consider that necessarily a reliable source but a starting place for further research. Also a single-carriageway expressway would be highway=trunk, expressway=yes, oneway=no.

Does the ref actually continue past the last interchange?

Is "Thrift Shop" literally the name of the store, or is this a thrift shop with an unknown name?

Just a heads up, cameras shouldn't be part of road relations.

I corrected the address and website. Where's Johnny Bench Drive?

This camera is located in the street and replaced the traffic signals?

Is this US 271 Bus route or US 271 Business? If it's a business route, it should have business spelled out to avoid ambiguation.

Sure, especially since the proper conditional speed is already on the following segment eastbound.

names aren't refs; there's no reason to duplicate the description of a route relation to the name (and misleading since some routes do have names).

I went ahead and tried fixing this up for you... took some searching along the road to find the compacted gravel section, and added asphalt as the surface to the paved parts. Made a multipolygon to create an outline for the picnic area.

Looks like you added the address to the road, I added the transfer building and put it on that.

County road numbers aren't names or alt names, they're refs.

Not sure how 76th got deleted but I went and re-added it.

If you're really in the dark on how to classify something, highway=road works as "there's some kind of traversable way here but I can't tell/don't know what kind".

Be sure to change or remove source:maxspeed as well.

Please spell out all words in the street name, like "Northwest" and "Terrace". Computers are good at creating abbreviations but bad at expanding them accurately, so OSM doesn't tend to abbreviate in value entries.

You can confirm this information yourself by contacting the Indian Nations Council of Governments and requesting the address database.

This might need some adjustment since the location seems to be in the verge between the parking and the sidewalk. I would hazard to guess this point was meant to go in a building, I'm just not sure where to be able to fix it.

With the exception of only about 3 or 4 streets, all streets in Tulsa start and end with a cardinal direction. The county's official map includes this information, and there's several signs that include both the lead and trailing direction (though there is no consistent signage in Tulsa, nobody seems to care enough to make consistent signs).

Be sure to update or remove source:maxspeed=* when changing maxspeed=*
