I see what you mean, but did you read the wiki for highway=unclassified? https://wiki.openstreetmap.org/wiki/Tag:highway%3Dunclassified

It says it’s for minor public roads that are *outside* residential areas, meaning outsides cities and villages, just random roads in the middle of nowhere.

These roads are right in the middle of El Oulfa. If you wanted to express the fact that they are “major” roads as in they are a lot more used than a normal residential road, then you should tag them as tertiary, secondary or even primary roads, depending on how much they are used. I myself don’t know how the traffic is there, but if you take a look at Boulevard Al Massira or Boulevard Zerktouni, you’ll see that they are tagged as primary roads. Boulevard Bir Anzarane is secondary, Rue Normandie and Rue Ain Harrouda are tertiary for example. You seem to have a lot more knowledge about El Oulfa so you decide how to tag them accordingly.

It’s great to see that someone edits around El Oulfa, thank you for your work.
