Try a new road venue (9)
I believe the answer is:
endeavour
'try' is the definition.
(I know that try can be written as endeavour)
'a new road venue' is the wordplay.
'a new' indicates anagramming the letters.
'road'+'venue'='roadvenue'
'roadvenue' is an anagram of 'ENDEAVOUR'.
(Other definitions for endeavour that I've seen before include "Aim" , "First space shuttle to visit the International Space Station" , "Captain Cook's first ship - DCI Morse's first name" , "Try - Cook's ship" , "Strive - over a nude (anag)" .)
