The fire has charred more than 33,000 acres, which amounts to nearly 51 square miles."That fire came through like a freight train," described John Tripp, incident commander with the Los Angeles County Fire Department. "We've never seen a fire come into Sand Canyon like that and neither have those residents."The Acton evacuation includes homes along Agua Dulce Canyon Road north to the 14 Freeway, Crown Valley north to the 14 Freeway, and all of Soledad Canyon and Bootlegger Canyon, Los Angeles County fire officials said.Sunday afternoon, the northbound 14 Freeway was shut down from the 5 Freeway to Soledad Canyon, and southbound lanes were closed from the I-5 to Avenue M.
