Pontem comburam cum perveniam, ¿perhaps? And for the record, I like “via longa”; couldn’t that refer to “open[-ended] road, road without end”?

There are no recorded uses of it like that, that I’m aware.
For “I’ll burn that bridge when I come to it”, maybe: “pontem incendam quando ad illum veniam”.
