The state Department of Transportation closed both lanes of the highway east of the Coal Creek Bridge, just east of Glacier, at 9:30 Saturday night due to falling trees.
DOT maintenance crews re-opened the Mount Baker Highway around 9:45 Sunday morning.
The highway was closed Tuesday through Friday last week after wind and snow sent more than 175 trees down across the road.
DOT spokesperson Dave Chesson says that it took a team of three excavators to remove all of the trees.
He says crews have been diligently working, in spite of obstacles, to make the road passable for people looking to take advantage fresh new snow at the Mount Baker Ski Area.
