It appears this changeset adds a duplicate road on top of another already existing one. This isn't something that should be done, any modifications to a road network should update existing data or add new data only if it doesn't exist. Here, you've added new data when it already exists. 
If you're curious for more information, you can check out the OSM wiki page for this general guideline at https://wiki.openstreetmap.org/wiki/One_feature,_one_OSM_element

I've reverted this changeset as well.
