Officials are assessing the damage following a fire on the James Street Swing Bridge tonight. Chief John Hay says firefighters were called to the scene around 7 o'clock and found smoke and flames coming from the structure. He says it proved to be a very stubborn blaze because of the creosote on the train tracks. Hay adds it's too early to say what caused the blaze and says the bridge will be closed to vehicle and train traffic until it's deemed safe.
