Burbank Firefighters responded to the Northbound I-5 near Buena Vista this past week for a grass fire between the number 3 and 4 lanes, they had to close the freeway to ALL traffic while attempting to extinguish the burning debris in a separation of the freeway concrete. The first Engine Company requested an additional Engine, and a Water Tender for it’s water supply and the fire still didn’t go out. The additional responding units then went below the freeway into the Cal-Trans Storage yard and found the hot debris had fallen on a log pile and caught that on fire. It was determined that birds and debris got between the lanes in a separation and unknown sources (because birds don’t carry matches) started the fire. The responding units then called a Truck Company and they extended their ladder and deluged the area to extinguish the blaze. CalTrans requested a Safety Engineer to determine that the bridge was safe to travel on and after an hour the lanes were open to some very unhappy drivers.
