In mid August 2014 we did this (southbound) by arriving at the construction at 5pm and riding until dark, then rising early to get through the rest. In most of the 27 miles the surface was adequate to good. The closure barriers were not up when we passed, but it appeared that the southermost 8 miles were the actual closure area.
We have heard of angry workers and conflicts from other travelers trying to cross this, but we had no trouble, nor did another couple on the same day.
If I had it to do again I'd just do the suggested reroute if only because of the length of the construction zone.
