Rockfall along El Portal Road, the continuation of Highway 140, forced a one-lane traffic control heading toward Yosemite National Park on Saturday morning.
Vehicles were backed up for a couple of miles from the park entrance as the cleanup was undertaken.
The rockfall zone was cleared of debris and normal traffic patterns restored about 9 p.m., Park Public Affairs Officer Jamie Richards said.
A slide a week ago left the road closed for the better part of six days, with cleanup finally completed last Saturday. About 4,000 tons fell in that slide.
Never miss a local story.
Meanwhile, the eastern entrance to the park via Tioga Road (Highway 120) remains closed because of the lingering effects of snowmelt.
