Route to get 'bravo' out of theatre land (7)
I believe the answer is:
roadway
'route' is the definition.
(roadway is a kind of route)
'bravo out of theatre land' is the wordplay.
'bravo' becomes 'b' (phonetic alphabet: alpha, bravo, charlie etc.).
'out of' is a deletion indicator.
'theatre land' becomes 'broadway'.
'broadway' with 'b' taken away is 'ROADWAY'.
'to get' is the link.
(Other definitions for roadway that I've seen before include "On which vehicles travel" , "Traffic surface" , "Surface travelled over" , "Part of street for traffic" , "Thoroughfare" .)
