Hi Nona Mostafa,
Thank you for your changes. You probably changed this road from trunk to motorway because the other part was changed to motorway but not this one, so you made the "logical" move. I just wanted to inform you that the user that originally changed the classification made some very dubious changes to the whole road network of the city. This road is not a motorway, it is still a trunk (you would think a motorway doesn't have roundabouts...). I left a comment of one of his changesets https://www.openstreetmap.org/changeset/160089188#map=13/33.54039/-7.70293. Just wanted to let you know. Thank you for your great edits.
