Eliwana Mine Bridges

Fortescue Metals Group’s (Fortescue) Eliwana mine is located 140 kilometres to the west of Solomon in Western Australia’s Pilbara region. Spanning over 30 kilometres the operation includes 143 kilometres of rail linking to the Hamersley rail line and a 30 metric tonnes per annum dry ore processing facility.

BG&E provided civil and construction engineering services for Fortescue, including the detailed structural design of two bridges, arch and culvert structures associated with the Eliwana project, in addition to construction support services, leveraging experience in the construction of steel bridges in the Pilbara region. The unique bridge designs consisted of separate rail and road bridge superstructures supported by a shared substructure. Both bridge superstructures comprised modularised steel though-girders with the first featuring two twin 31.5 metre spans and the second consisting of six spans totaling 228 metres in length.

With over 50 years’ experience, our multidisciplinary teams provide complete design capabilities to reduce emissions and are committed to reducing the impact that mine sites have on the environment, while supporting the production of materials for sustainable commodities.
