In February of 2019 a rockslide on California SR-2, the Angeles Crest Highway, buried the road in 30 feet of rubble and closed the road indefinitely. Caltrans worked to clear the remaining landslide debris and reduce the hazards in the area. Part of the work involved using a spider excavator to excavate from the head of the landslide down. This is one of the best videos I’ve seen showing this unique piece of equipment in action. There is also a nice article about the project on The Drive.

A massive rockslide closed a busy interstate route last week near the border between Tennessee and North Carolina in Pigeon River Gorge. This area has had landslide problems in the past. In 1997 a rockslide in the same area closed the freeway for approximately 3 months. (Photo from Landslides Under a Microscope Blog, original source not cited)
I have yet to see volume estimates, but The Charlotte Observer quoted a highway patrol officer who was at the scene:
He said the roadway is covered by a gigantic mound of debris, from pebbles up to house-sized boulders. The pile is 40 to 50 feet high, Williamson estimated, and hundreds of feet long.
More info and video after the break. […]
