Sind die Hausnummnern 7 und 9 hier vertauscht ?

suspicious tag
natural = IFMS Instituto Federal de Mato Grosso do Sul

The unusual tag highway=speedway + area=yes is used here for the area around a raceway stadium.
The raceway is also mapped with highway=raceway, so I wonder if the area should be mapped with landuse=commercial ?

two highways with name Rua R 20 start here. Is that intended?

highway=unclassified ends at
footway?

needs review:
1) many highway=tertiary roads which are probably residential or path
2) ref and name tags seem to describe the properties
3) lots of duplicated buildings

Bing shows no bridge here,
relations and way around
lake are messed up

was bedeutet
natural=Tor 3 ?

most residential roads in this area are tagged with highway=unclassified instead of highway=residential
