Longest single span?

[Gray]

Well, the Map Pack 1 levels 15 & 16 have very long spans, you can check the bridges on http://pontifex.phantomtech.info" target="_blank">DWN's site.
Even longer ones should be possible, though.

It is possible that the question has been asked before, in which case my apologies.

Is there a maximum length of single span possible with unlimited funds and materials? Has anybody tried it or is it to big for the best PCs today?

Thanks
