Northbound traffic on Division Street has been shut down as firefighters finish putting out a fire at a used car dealership. A passerby saw flames inside Becker Automotive at 3518 N. Division around 10 p.m. Monday, said Spokane Fire Department Assistant Chief Brian Schaeffer. Firefighters forced their way into the locked building and were able to put the fire out quickly, Schaeffer said. “Fortunately somebody called,” he said. The cause of the fire is under investigation. Northbound Division Street is expected to be closed until about 11:30 p.m.
