Hopetoun Bridge Replacement

Project Overview

Bridge 5023 located at SLK 5.57 on Springdale Road crossing the Jerdacuttup River was a single span concrete structure that was severely damaged by flooding in 2017.

Due to the nature of the watercourse feeding into a lake system and to reopen Springdale Road, a causeway was constructed over the remains of the old bridge structure given the slow receding of the waterway.

The new bridge will be able to accommodate a higher flow and will be lifted approximately 2 to 3 meters above the original bridge construction.

Recent flooding has damaged the causeway with the need to construct a new permanent structure that will improve the serviceability of Springdale Road crossing the Jerdacuttup River and lake system.
