You don't mention which direction you're going.  Watch out in northern
Oregon, as I've already added relations to some of I-5 and I-84, and I
think the entire length of I-205.  You might want to see if those are
suitable for re-purposing.

JOSM or Merkaator(sp?) are probably the best tools for the job.  JOSM
now has modeless Potlach style editing (and has for a couple months
now), so you might want to give it another go.  It also does a lot of
other useful things like highlight bogus relations, unclosed ways, and a
lot of other things that Potlatch doesn't do, that potlatch makes
difficult to do, or that potlatch visually obfuscates.

You also don't have to stop editing just because the server crapped out
on you (assuming you already have data), or wait around after every edit
for it to save (you just bulk upload your changes when you're done).

JOSM also has a relations editor that will make you wonder why you
waited so long to give JOSM another go.
