A concrete road bridge (fixed object, specially designed) with steel girders, accessing the Interstate Rail Passanger terminal platforms at Keswick South Australia. It has a clear span of 20 metres, is 8.6 metres between kerbs, with mass concrete abutments on a Reinforced Earth Retaining Wall. The access ramp at right angles to the main structure is approximately 90 metres long.
The model has ballustrading, Armco guardrails and overhead lights that show up at night, and roads may be connected to the ends. The road shown on the mode will update to any road connected to it. Traffic will use the structure. The rotation point is the front wall at Abutment B (near the centre of the structure).
