You'll be on 3N for about 11 miles. Go past the Lowell connector. Then past the 495 exits, under the underpasses. Don't go over the underpasses, I can't stress this point enough, the underpasses are for going under....for some reason "underpasses are for going UNDER" comes to me everytime I hear the phrase underpass... it was an especially lovely bit of gratuitous goofiness, since there was no way in particular to get over on those underpasses from that road.
