Hello LockOnGuy;
According to the rules for OpenStreetMaps about the classification
in "motorway" was a very high classification in this area to be "motorway ", is a description for "motorway" High capacity, highway designed to safely carry fast motor traffic.
For more information on how to use the "motorway"
https://wiki.openstreetmap.org/wiki/Tag:highway%3Dmotorway
So it is more suitable to be "secondary" as an overview in this location.
I did some research and I found this video showing the tunnel and Yafa Street also:

If you have an official page for the Iraqi OSM community it will be helpful for us.
Thank you for your understanding.
