Where (Adverbial Phrase of Place)
An adverbial phrase of place states where something happens. For example:
I used to work in a fire-hydrant factory. You couldn't park anywhere near the place. (Steven Wright)
Opera is when a guy gets stabbed in the back and, instead of bleeding, he sings. (Ed Gardner)
Although came along does not describe a specific place, it is definitely an adverbial phrase.
Adjective phrases, on the other hand, are phrases whose head word is an adjective.
