A bulldozer clears mud on I-70 after mudslides in Rocky Mountains, Colorado, the United States, on July 30, 2021. Shortly after 9:00 p.m. local time Thursday, Interstate 70, the major transportation artery between east and west America, was frozen by an avalanche of rock, mud, and burn debris and the authority predicted it could not be reopened this weekend.
