Moorebank Avenue Interchange
M5 Motorway

The project involved construction of a grade-separated interchange within an operating motorway during a nine months construction period. The entire bridge superstructure used precast elements including columns, piers and abutment headstock beams, two 18m long simply supported spans of 1000mm deep Super-T girders and outer angled trimmer beams and deck planks.

The unprecedented level of precast usage required absolute precision in both manufacture and installation. Repeated and exacting design review and checking involving SCI ensured that constructability was inherent in all of the design.

Aesthetics was a most important consideration for the prominent, 64m wide bridge. Attractive, highly visible centre piers and headstocks were designed to frame into Y-columns with surface relief to provide architectural interest. The high quality off-form Class 1 finish achieved on column and pier surfaces further added a stylish appearance to the structure.
