Westgate Bridge Suspended Access Platforms

Structural Designer

Malachy Ryan, Alan White

Client Name

APS Contract Services


In the project to widen the M1 motorway in Melbourne from eight lanes to ten, the strengthening works required to the Westgate Bridge were critical. The West Gate Bridge Alliance commissioned APS to provide access to the concrete approach viaducts, the steel box girder sections and the concrete soffits at the bridge piers. The design of these suspended platforms was performed by Alan White Design Ltd using a modular space frame access system which was designed, configured and modified to suit the particular aspects of this project.

Judge's comment:

"The West Gate Bridge Suspended Access Platforms represent an example of structural engineering design at its best. A clear understanding of the problem and its constraints, tackled by inventive and imaginative thinking, resulted in a
practical, eminently workable solution, the cost of which is an order of magnitude lower than that of more conventional methods. This is a classical case which serves to demonstrate the immense value structural engineers can bring by
adopting a well-informed and pragmatic approach to problem solving."
