The episode as NWS GJT wrote it up.
A rock slide that included ten large boulders occurred in Glenwood Canyon early on New Year's Day. The slide fell on Interstate 70, damaging westbound and eastbound lanes. One boulder tore a 3-by-4-foot hole through the outer lane of the suspended section of eastbound I-70. The average weight of the boulders was estimated at three tons. This slide was thought to be caused by a freeze and thaw cycle that had been ongoing for over a week.

NWS Grand Junction, CO wrote its last area forecast discussion before the first event at Jan 1, 3:45 AM MST, 5 hours 30 minutes earlier.
