Shifting the Canning Bus Bridge sideways

The Perth Mandurah railway proposed in 2002 required the replacement of an existing Kwinana Freeway bus bridge. As a cost saving alternative the successful tenderer proposed that the existing bridge superstructure be moved rather than rebuilt. In 2005 this curved prestressed concrete bridge superstructure was successfully moved a distance of 9.5 metres south west of its original location to remain in use carrying buses from Canning Highway onto the north bound Kwinana Freeway. This paper provides an example of the economy which is achievable by modifying and re-using an existing structure, but also shows that the bridge engineering challenges for keeping old structures are often more difficult than designing new ones.
