The BW-03-006 Culvert Package represents a landmark achievement in sustainable infrastructure and practical engineering within the rail corridor. Tasked with rehabilitating access roads plagued by scouring and water damage, our team developed a pioneering Sleeper Causeway solution. This project not only restored critical access but also redefined how recycled materials are used across the Aurizon network, setting a new benchmark for cost-effective, durable drainage solutions in remote environments.
