Firefighters were at the scene of a major fire at a Central Austin home on Saturday night that has closed a key artery to traffic. The fire at 4514 Red River St., at the intersection of Red River and East 45th Street, was sparked at around 9 p.m., as indicated by time stamps on Austin Fire Department updates via Twitter. The scene of the fire is diagonally opposite of the Red River Church, 4425 Red River St. as indicated by Google Maps. A firefighter had to be hospitalized briefly after helping fight the blaze before being treated and released overnight, according to officials. One resident was displaced, but the occupants of the home were accounted for by HOA officials as being away on summer vacation. Fire officials providing updates on social media conveyed a stubborn conflagration that posed challenges in extinguishing.
