Louvre bad designed the French way? (9)
I believe the answer is:
boulevard
'french way?' is the definition.
(a road in France)
'louvre bad designed' is the wordplay.
'designed' indicates anagramming the letters (designed with the letters).
'louvre'+'bad'='louvrebad'
'louvrebad' is an anagram of 'BOULEVARD'.
'the' is the link.
(Other definitions for boulevard that I've seen before include "Broad urban road" , "Long, wide avenue" , "Broad avenue" , "Wide city road" , "Wide tree-lined street" .)
