I've heard the expression "let's cross that bridge a little further down the road" to convey something I understand a bit like: "let's take that difficult decision a bit later" or "let's take on that challenge a bit later". Can the expression be interpreted like that? Any other ideas?
"Let's not worry about that until further down the road," and "Let's cross that bridge when we get to it" are two ways to idiomatically express "Let's defer that until later, and stay focused on the topic at hand right now."
The phrasing you gave sounds like a combination of those two idiomatic expressions - be it inadvertent or deliberate (much like when someone says "ginormous")
