YOU SAID:
cross that bridge when we get to it
INTO JAPANESE
私たちがそれに着いたときにその橋を渡る
BACK INTO ENGLISH
Cross the bridge when we get to it
INTO JAPANESE
到着したら橋を渡る
BACK INTO ENGLISH
Cross the bridge when you arrive
INTO JAPANESE
到着したら橋を渡る
BACK INTO ENGLISH
Cross the bridge when you arrive
That didn't even make that much sense in English.
