The narrow swing catanery bridge was built behind the school across the Deep Creek downstream from the bluestone Bulla Bridge. It was built so that children who lived on the south side of Bulla Township could access the school more easily and in shorter time than if they had to go by the main roads.The bridge was constructed in the days when most children walked to school. The use of this bridge cut the children's travel time and distance to school quite considerably and was used for many years until the school was closed in 1996.A coloured photograph of the children on a narrow swing bridge and the path they used to approach the bridge over open ground. bulla primary school, swing bridge, bridges, catanery bridge
