Hundreds of bridges have been impacted by Cyclone Gabrielle across Aotearoa.
Work is underway to assess them on a case by case basis, and set up temporary bridges known as Bailey Bridges.
Daniel Chrighton is national engineering manager for Downer.
He lives in Gisborne and is directly involved in the infrastructure response. He explains how the temporary bridges are installed and how safe they are until there's permanent structures in place.
