Here are roads — ah, so go further, travelling round! (13)

I believe the answer is:

thoroughfares

'here are roads' is the definition.
(thoroughfare is a type of road)

'ah so go further travelling round' is the wordplay.
'travelling round' indicates an anagram.
'ah'+'so'+'go'+'further'='ahsogofurther'
'ahsogofurther' anagrammed gives 'THOROUGHFARES'.

(Another definition for thoroughfares that I've seen is " Roads".)

I've seen this clue in The Times.
