Hi, I found that you had made some changes in Pune on the way-id w791027426 and connected other service roads. Although, these roads are service roads, but they are working as a frontage roads. As per the OSM classification, a frontage road running parallel to the major road should be classified as tertiary road. In this case this service road is carrying high volume of traffic and giving access to other major roads, that's why in this case we classify it as primary road.
