Analise, I've not made the crossing, but there's also an option a little west of I-87, on NY 22 at Mooers. (That's the same NY 22 that used to include the Bronx's Grand Concourse as part of its route.) You can take US 11 west to NY 22, or you can bail out from I-87 at Exit 41, and take NY 191 west to NY 22 north.

A little OT, but as of 4/1/11, Canada is closing a couple of little-used, part-time border crossings that are even further west of I-87; it looks like the U.S. may continue to staff them, however, which would turn them into one-way crossings.
