@Fernando,
Here is a simple tutorial to editing osm https://learnosm.org/es/beginner/id-editor/
This is probably due to this https://www.openstreetmap.org/relation/8339933#map=18/-34.47427/-57.84252
or the barriers(gates) along this geometry.
see https://maps.openrouteservice.org/directions?n1=-34.473729&n2=-57.842275&n3=18&a=-34.47321,-57.843586,-34.473723,-57.843672&b=0&c=0&k1=en-US&k2=km
I’m not sure on what the actual problematic thing is, or what tags would work in this case
