A new bridge, the end of lorry chaos? (7)
I believe the answer is:
anarchy
'chaos?' is the definition.
(I've seen this in another clue)
'a new bridge the end of lorry' is the wordplay.
'new' becomes 'n' (abbreviation as in New Testament NT).
'bridge' becomes 'arch' (I've seen this before).
'the end of' suggests the final letters.
The last letter of 'lorry' is 'y'.
'a'+'n'+'arch'+'y'='ANARCHY'
(Other definitions for anarchy that I've seen before include "General disorder" , "Lawlessness; chaos" , "State of lawlessness and disorder" , "State of civil disorder" , "Uncontrolled disorder" .)
