Hi,     
The map you sent above https://web.archive.org/web/20240110201616/https://api.amanatbaghdad.gov.iq/images/bfeea80c-715b-4b12-b176-66ffc5a16434.jpg by Baghdad Municipality say "Ameen Street" not 77th street.      
You told me previously that a guy from Baghdad Municipality sent you official maps made by the Baghdad Municipality, please check them, and you can see that the name of the street is Ameen Street and there might include the number of the street next to it just the number "77" without saying "77th street"         
And this street name is +50 year old. I'm also local, and I did heard people say "77th street" yes, but that doesn't mean that is the name of it. I also heard people say "Ameen Street" maybe even more though, and since the 77th street is just the road number, it shall be in the number tag, and the street name be in the name tag. There is no harm to have "77th Street" in alt_name even though it is not a name.         
Regards.
