see you down the road
A phrase made popular by circus clowns and other circus workers. It literally means what you would think it means. It's a form of "see you later". People in the circus absolutely hate saying goodbye, because goodbye is final. See you down the road means that although you're leaving right now, our paths will cross again! Like the train tracks that we travel on from city to city.
I hope you have safe travels, see you down the road!
