Hi ChaireMobiliteKaligrafy, Thanks for reaching out. 
Towards the northeast, the service way 1212714833 was connecting two residential roads and was only about 1 meter in length. I thought of maintaining the same configuration created by you, but extend the segment, but now I see you have updated it. Thank you for making the corrections. Anyway, I should have left a more descriptive changeset instead of the default one, to avoid confusion.
