Hello Agus K,

Thank you for choosing to contribute to the OSM project. I want to bring to your attention some duplicate features that you've added (https://www.openstreetmap.org/way/1164312149 & https://www.openstreetmap.org/way/1164312148). These features already had ways corresponding to the roads they're meant to represent. When adding route relations, it's best to use the ways that are already present in the data, and to split them as necessary to match the extents you require. Here is some documentation from the OSM Wiki which may help to clarify mapping route relations and the single element policy: https://wiki.openstreetmap.org/wiki/Relation:route#How_to_map ; https://wiki.openstreetmap.org/wiki/One_feature,_one_OSM_element ; https://wiki.openstreetmap.org/wiki/Key:highway .
