based on the aerial imagery in the area the bare rock looks more like a Stone groyne to me, is that correct? man_made=groyne . I ask because I have seen similar structures mapped as groins before in Miami Dade County.

as per the latest imagery there aren't any bike lanes or marking indicating for bikes to share the road with cars on this section of US 1 South Dixie Highway so bicycle=yes is incorrect from what I can tell

please respond

please respond

how have you confirmed (or not) that there is no longer and construction on Northwest 6th Avenue?

please respond

the official FDOT website for the project that the construction on Northwest 6th Avenue is for still lists the section of Northwest 6th Avenue that you marked as not under construction as still being under construction. also if you look at Northwest 6th Avenue it is a tertiary road and was tagged with construction=tertiary so it should be tagged as such, not a service road. also when marking a road as not under construction any longer please ensure that you remove the construction=* tag from the from the road ways.

next time please leave a better changeset comment, for more info please see osm.wiki/Good_changeset_comments .
Also just adding a name without and other tags telling you the purpose the object isn't very useful, what is "Service", what is done in this building, please remember that names are not for descriptions, for more info see osm.wiki/Names#Names_are_not_for_descriptions

the official miami dade open data hub has issues in some areas but for addresses and some other pieces of information it is the best we have right now outside of survey when that is possible, or up to date streetside photos when available like from mapillary https://www.mapillary.com/

as mentioned above the address of the hospital as a whole is on Alton road, what doesn't mean that the road within the hospital is Alton road. ways like way/1002417849 already have Alton road on them, this doesn't mean that the road you tagged as Alton road within the hospital is, it just means that hospital as a whole is, including the buildings that are part of the hospital.

in the miami dade open data hub address dataset the building of way/435519612 seems to have an address of 4300 not 4308, why did you make this change. and where did you get the rest of the addresses in this changeset.

Alton road seems to be the name of the primary road which passes by Mount Sinai, I don't see evidence of it also going into the Hospital grounds, if this is to fix address issues, there isn't much we can do as the addresses in the hospital point to this road as the hospital as a whole is on this road.

whats your source for this?

in this changeset you added a name to a address without specifying what type of business this is, I have marked it as an office as to have something but I doubt that that is all of the information that could be placed on this POI. So the question becomes what type of business is "NOVA 360 LLC"?

also looking further into the changeset there are source:name=* tags that imply google was a source for at minimum part of this as we cannot use google maps as a source for this OSM changeset and we are not allowed to use google as a source as their license is incompatible with the OSM license.

then why are there dragged nodes from Canada and Europa?
There are also ways like way/1432435588 that cross highways, that are not on imagery available in iD and not tagged as a bridge or tunnel, or even layers.

This is very likely some kind of vandalism as it adds allot roads with some of them dragged to end across the world; if I was being charitable this was an attempt to add historical features with some dragged nodes. But even then the historical tagging is not present.
