Try putting the preposition 'at' in front of the noun. If the meaning is unchanged then the noun is being used adverbially.

Just a note, because I have seen reached being used instead of arrived before: this is not standard. You reach the station, and you arrive at the station. This is not what you asked, yet it might be relevant.
