On 22 January, the fire broke containment lines and headed north thanks to wind levels and hot conditions, the fire also caused the closure of the Pacific Highway and train line. The suburb of Berowra also came under direct threat with residents urged at the time to prepare their properties. The railway station and a train that had stopped there came perilously close to being consumed by the bushfire. Later on 22 January, the fire front was slowly contained, allowing all three avenues to re-open by nightfall.
