Currently at 175 event progress, can I still get the main event building?

I find this event pretty boring so I've just been winging it so far. But that main building Luchon something, looks nice and I wouldn't mind putting in extra effort to get it

Thing is I don't even know what city I'm currently on, so I'm wondering if it's possible to have it fully leveled if I do one city at day with minimum 25 tasks completed
