Bridge crossing international state (5)
I believe the answer is:
spain
'state' is the definition.
(Spain is an example)
'bridge crossing international' is the wordplay.
'bridge' becomes 'span' ('span' can be a synonym of 'bridge').
'crossing' indicates putting letters inside.
'international' becomes 'i' (abbreviation eg in IMF).
'span' enclosing 'i' is 'SPAIN'.
(Other definitions for spain that I've seen before include "Iberian 4" , "Country bordering Andorra" , "EU country" , "ditto" , "Iberian country" .)
