This is still correct. It's a transitional verb. The prepositional phrase just describes where, in this case.
An intransitive verb requires an object to be grammatically correct. If I use another example
'The construction team raised the bridge.'
I cannot omit 'the bridge' - I must use a word. Even if I use a prepositional phrase
'The construction team raised in the night.'
I still have an incomplete sentence. The prepositional phrase is not in place of an object, it doesn't 'do the same job as a direct object'.
