Hello Sandalss,
Thank you for your contribution to OpenStreetMap in Oman.
I noticed you added a "ref=BE" tag in some sections of the Batinah Expressway.
Here are examples of those roads:
https://www.openstreetmap.org/way/617090848
https://www.openstreetmap.org/way/565166768
However, this source indicates the road's reference number is "ref=N1": https://mjla.gov.om/decisions/ar/1071/show/1188
If you have a more current source than this document, could you please share it with us?
Regards,
