I travel across far side of town on bypass (6)
I believe the answer is:
ignore
'bypass' is the definition.
(I've seen this before)
'i travel across far side of town on' is the wordplay.
'travel' becomes 'go' (synonyms).
'across' indicates putting letters inside.
'far side of' suggests the final letters.
'on' becomes 're' ('on' can be mean 'with reference to').
The final letter of 'town' is 'n'.
'go' enclosing 'n' is 'gno'.
'i'+'gno'+'re'='IGNORE'
(Other definitions for ignore that I've seen before include "Slight" , "Fail to consider" , "Deliberately disregard" , "Forget" , "Turn a blind eye to" .)
