Hello felipeeugenio! 
First of all, thank you for reviewing my contribution and adjusting tags, categories and names. I'd noticed that D401 was tagged as oneway, then I unset 'yes' for it. I actually don't know if this tag is necessary at all. 
In reality, all roads that I've crossed in that region were two ways, including this path in D401. Maybe in the past this path was one way. 
Thank you, If you need more info, please let me know.
un saludo desde Brasil
