Possibly gets away via entrances or exits (8)

Ross

I believe the answer is:

gateways

I'm a little stuck... Click here to teach me more about this clue!

'entrances or exits' is the definition.
I can't judge whether this definition defines the answer.

'possibly gets away' is the wordplay.
'possibly' indicates an anagram.
'gets'+'away'='getsaway'
'getsaway' is an anagram of 'GATEWAYS'.

'via' is the link.

Can you help me to learn more?

(Another definition for gateways that I've seen is " Entrances and exits".)

I've seen this clue in the Evening Standard.
