The Seaford Rail Extension Project, currently under construction to the south of Adelaide, South Australia, requires a 1.125km long viaduct to cross the Onkaparinga Valley and River. The solution chosen is an incrementally launched, concrete box…

Modular bridge expansion joints (MBEJs) are utilised when the movement range at a bridge expansion gap exceeds around 300 mm, with the largest MBEJ installed to date accommodating a movement range in excess of 2100 mm. Traditionally MBEJs have been…

The 2.5km long West Gate Bridge comprises an eastern and western concrete approach viaduct, 871m and 670m respectively in length either side of the 850 m long cable stayed steel box girder main span section. The key objective with the West Gate…

The main structural components of the railway bridge at Bankstown, installed in January 2011, are two 18m steel welded arch trusses with an overall height of 3.5m. Each truss comprises fabricated box sections for the chords and I sections for the…
