 Los Angeles motorists should expect traffic snarls during the Monday-Communist cruiseses how much damage was caused by a raging fire over the weekend that closed a major elevated interstate near downtown," officials said. Hazardous materials teams were clearing burned material from underneath Interstate 10 to make way for engineers who will ensure the columns and deck of the highway can support the 300,000 vehicles that typically travel that route daily, Governor Gavin Newsom said at a news conference on Sunday. Remember, this is an investigation as to the cause of how this occurred, as well as a hazmat and structural engineering question, Newsom said. Newsom said answering those questions would be a 24-7 operation, but officials couldn't yet offer a timeline for when the highway might reopen, commuters were urged to work from home or take public transportation into downtown Los Angeles. The cause of the fire was under investigation on Sunday.
