Hello Dineshkumar, Welcome to OSM.  Please visit  India page on OSM wiki (https://wiki.openstreetmap.org/wiki/India) and  join OSM India Telegram channel (https://t.me/OSMIndia).
A bypass is created when a major road that has lot of traffic goes through a place. The road segment between the bypasses that goes through place needs to have a lesser grade of highway. You have changed the tag for the whole road.  Please provide a response or update the edits for me to revise the tags.  Happy mapping!
