Tourle Street Bridge is part of the Tourle Street and Cormorant Road duplication project in Newcastle, New South Wales. The project consists of 3.8km of new road alignment including duplication of the existing Tourle Street Bridge, requiring demolition of an old steel truss bridge on the new alignment. The new 11-span bridge is 330m long, 12m wide, and is of composite prestressed concrete Super-Tee girder and reinforced concrete deck slab design. The bridge accommodates varying sag and crest curve vertical geometry to fit the road alignment and variations in the sub-structure design for both over-river and viaduct applications.
Quick model facts:
Extensive use of cast-in-place reinforced concrete elements and phasing
Steel modelling objects used for traffic railings and guardrail interfaces
Approximate totals: 6000 cubic metres of concrete and 1000 tonnes of reinforcing steel
Developed collaboratively by several modellers across national offices in a multi-user environment
