Easy tasks reversing bridges (5)
I believe the answer is:
snaps
'easy tasks' is the definition.
(I've seen this in another clue)
'reversing bridges' is the wordplay.
'reversing' is a reversal indicator.
'bridges' becomes 'spans' ('span' can be a synonym of 'bridge').
'spans' backwards is 'SNAPS'.
(Other definitions for snaps that I've seen before include "Informal photographs" , "Spells of cold weather" , "shots" , "Photos" , "Breaks in two" .)
