There's even a diversion going round a bend in the road! (6)
I believe the answer is:
avenue
'road' is the definition.
(avenue is a kind of road)
'there's even a diversion going round a bend' is the wordplay.
'there's' means one lot of letters go next to another.
'diversion' is an anagram indicator.
'going round' indicates putting letters inside.
'a bend' becomes 'u' (a U-bend is a kind of bend - pipe under sink**).
'even' put next to 'a' is 'evena'.
'evena' with letters rearranged gives 'avene'.
'avene' going around 'u' is 'AVENUE'.
'in the' is the link.
(Other definitions for avenue that I've seen before include "Wide street or way of approaching" , "A broad thoroughfare as in New York" , "Tree-lined approach to a house" , "Thoroughfare, boulevard" , "Wide (tree-lined) street" .)
