I am not in tabriz but live in iran and I'm sure the  municipality never uses a strange name "دلتنگی" for naming a street!.  the real name is "دانشگاه" 
It means university because this street is next to the university. and this user never answer my comments to send any prove.  These photos is of the street view provided by "Nashan" app from "دانشگاه" Street: https://imgur.com/a/50hfAwM
