Hill River Crossing

Hera Engineering was tasked with the full pricing design of a proposed pedestrian crossing at the remote Hill River, involving schematic design for the bridge and foundations. The primary challenge was the critical transport and installation requirements, as the crossing lacked access via sealed roads and traversed a waterway with no internal span access. To address this, a precast concrete girder (T-Roff) bridge was chosen for its cost-effectiveness and low maintenance in the coastal environment.

Hera Engineering collaborated extensively with contractors, suppliers, transport companies, and crane operators to ensure the feasibility of transporting and installing the precast bridge at this remote location. Consulting with the relevant Statutory Authority, Hera determined the crucial ultimate case water level, designed support abutments, and carefully set out the foundation and bridge deck to avoid negative impacts on the waterway’s hydraulic flows.
