Hello Sandalss,
Thank you for your contribution to OpenStreetMap in Oman.
According to our information, the correct way to the road network for the branches for the street  shall be of the same road classification, but I noticed you changed the classification of some streets to link
Examples of streets:
https://www.openstreetmap.org/way/498352593
https://www.openstreetmap.org/way/798968764
https://www.openstreetmap.org/way/798968781
Do you have a specific concept to implement in the country?
Regards,
