The Great Northern Highway (GNH) Fortescue Metals Group (FMG) Solomon Road over rail bridge, is a single span arch bridge, carrying the GNH over the existing Solomon Railway Works and includes realigning associated sections of existing road. This infrastructure is critical as it helps to facilitate FMG’s T155 expansion project in the region.
We provided civil engineering services, including the detailed design and documentation of the following:
- three railway bridges over waterways in concrete composite girders and concrete substructure designed for extreme flood events;
- one rail-over-rail overpass consisting of a steel through-girder superstructure with an in-situ concrete substructure, designed to resist the impact loads from heavy haulage rail trains; and
- one road-over-rail overpass on the GNH, designed as precast and prestressed concrete beams with a composite in-situ deck.
