A new haul road was required to access gravel reserves on the south side of Regional Road 73 (Fly Road). A super-span bridge overpass was selected to accommodate haul trucks. The culvert is 6.94m in height, 11.570m in width and has a length of 43.2m. It is designed with a soil arch with the footings set into bedrock. Timber blocks were used for a settlement mechanism to activate the soil arch.
