Diverse Hausnummern (?) in dieser Gegenf sind als name=* gemappt

Does this bridge really exist?

bing shows a playground here,
not a street

a few highways have useless oneway attributes like
onway="no;yes;-1"

way/215097179,way 213900046,way 209445450

Many roads with ref=375 here. This looks wrong

Adresse vermutlich
Gerhart-Hauptmann-Straße 2,
nicht Thomas-Mann-Ring 6

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?
