Engineers and geologists in Los Angeles are trying to work out how a slipping hillside on the Vasquez Canyon Road is pushing up the road.
The road has been slowly rising since last Thursday and is progressively getting worse. The cause is still not known. A Los Angeles County Department of Public Works official has told local media that the mountain itself is shifting.
All images are from the @LAPublicWorks Twitter feed, where the latest updates will be posted. The mountain is still sliding and said to be very dangerous.
