Aurizon – BW-03-006 – Sleeper Causeway & Culvert Package

The Project

At the Duaringa-Wallaroo rail corridor (113km to 117km), persistent scouring was compromising maintenance access and the structural integrity of drainage assets. Schwarz was engaged to deliver a resilient, cost-effective solution to stabilise access roads and remediate drainage inverts across high-flow areas.
