From the Loveland Reporter-Herald (Tom Hacker):
Plows working their way westward along the road bordered by tundra have topped the 12,183-foot summit and made it to Alpine Visitors Center, just west of the high point. Park officials say that barring high-altitude weather that can derail plans, the road should open May 24 when road crews from the Eastern Slope and Western Slope meet on the cleared road.
Memorial Day is the traditional opening date of the road.
