3.1 Crossings – Battery Culvert River Crossings (2.0)

Summary

This guide covers battery culverts which are a series of pipe or box culverts installed alongside each other to form a low profile crossing. The base river flow passes through the culverts, but during flood events, water flows over the top of the crossing. This allows for the dry passage of vehicles in base flow conditions but may result in the road occasionally being closed to vehicles for short periods during flood flow. Battery culverts need careful planning and installation to prevent failure.
