Why are the roads in many cities named after other cities?

Roads are named after other cities mainly because they are easy to remember.

Many choices of road nouns have a long history. At that time, when choosing names for roads, they would choose city names from other places for the convenience of being remembered. There were not many roads in the past, but they wanted to be remembered deeply by passers-by. Therefore, when naming, they would choose "to be remembered deeply", then the city name was the best choice; city names are easier to remember than other elegant words. , so city names have become the first choice for roads in many places.
