We went up from Manti about 2:30 and the traffic going down the canyon was stoped just before we got to Diamond Fork. It was stop and go until where it merged from 2 to 4 lanes then it sped back up. When we went home about 6pm and back up the canyon traffic was stopped passed the Highway 89 turn. If you were coming from Moab/Price that evening you were going to be waiting for an hour or more in that.
