Reported transport passage (4)
I believe the answer is:
hall
'passage' is the definition.
(I know that hall is a type of corridor)
'reported transport' is the wordplay.
'reported' shows a homophone (sound like).
'transport' becomes 'haul' (hauling is a kind of transporting).
'haul' sounds like 'HALL'.
(Other definitions for hall that I've seen before include "Large country house" , "Large public building" , "See 1" , "See 21" , "Toad ___ (Toad's home)" .)
