Bridge I lowered in US state (11)
I believe the answer is:
connecticut
'us state' is the definition.
(I've seen this before)
'bridge i lowered' is the wordplay.
'bridge' becomes 'connect'.
'lowered' becomes 'cut' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'connect'+'i'+'cut'='CONNECTICUT'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for connecticut that I've seen before include "state of the union" , "One of original thirteen US states" , "one of fifty" , "The Nutmeg State" , "America" .)
