How popular would it have to be for a main road to be built?

I heard that BTS debuted in 2013.

It is said that this is the first time BTS is holding a solo concert in Peru since their debut.

Perhaps that is why the excitement for Peru is already so intense. I heard that Sacramento Street has been temporarily named BTS Boulevard for a week, from the 5th to the 11th, and commemorative signs have been erected.

I hear that even the city center landmarks are turning purple. It really makes me realize once again just how amazing this is—just how popular it is that a main road is being built around it.
