Thanks. Problem fixed. Please check once again. These edits were initially performed in ID editor, so couldnt evaluate, JOSM is way ahead of ID editor. Thanks again

There is bypass but not a prominent one. Its a two lane road and not termed as national highway for now though there are plans to make it a six lane road. For now I suppose its better to leave it as mentioned.

I studied the guidelines of Highway tagging, I have a doubt in this regard, the guidelines state that NH should not be used to refer highways within the city, so does it mean that the NH 16 beside Sector 4 MVP should be renamed?

Sector 5 and 8 are correct. Sector 4 is actually sector 3
