Last month I ripped up a poorly hand laid roadway, and replaced it

made sure the way was laid down properly, and waited for another
render cycle. I then attempted to force a re-render through
informationfreeway. To date, the way is still a straight line between
the end points in Mapnik, but if you go into the Potlatch editor, the
proper way is sitting right there.

What gives?

My guess would be that the way is too long. Can you try chopping it up into sections, I'm not sure what the current best practice for way length is but you could start by trying somewhere between 5-10 miles. I'm not sure why that would cause a problem as you have put nodes along the length of it but that's what I'd guess. You mention forcing a re-render on informationfreeway, do you know that doing that will only affect the Osmarender/[EMAIL PROTECTED] layer. If you look at that layer you'll see that the tile containing your way is actually empty. I think this makes it more likely that way length is the problem.
