Full ticket price shown in street (12)
I believe the answer is:
thoroughfare
'street' is the definition.
(I've seen this before)
'full ticket price' is the wordplay.
'full' becomes 'thorough' ('thorough' can be similar in meaning to 'full').
'ticket price' becomes 'fare' (I've seen this before).
'thorough'+'fare'='THOROUGHFARE'
'shown in' acts as a link.
(Other definitions for thoroughfare that I've seen before include "Public road" , "Access - road" , "highway" , "Public way or street" , "Main road" .)
