San Francisco and Beaver Streets in Flagstaff will be blocked off at times over the next three days. Flagstaff Police Sgt. Cory Runge says a train derailment between Kingman and Flagstaff Tuesday left one person dead and another injured and the tracks in need of repair. He says as the tracks are being repaired Amtrak will be bussing people between Flagstaff and Kingman. Runge says the intersections of Beaver St. and San Francisco St. are expected to have long delays, as people are deboarding and boarding, between 4 and 5AM and 8:30 and 9:30 PM each day. Traffic will be redirected during these closure times.
