What if... Christchurch becomes the city of bridges?

Dr Alessandro Palermo, Senior Lecturer in Structural Engineering, Department of Civil and Natural Resources Engineering · What is the history of Christchurch bridges? · How did they perform during the Canterbury earthquakes? · How can we improve their seismic resilience? Is it worthwhile turning Christchurch into a city of iconic and innovative bridges? The Avon and Heathcote rivers embrace Christchurch city. Their winding path combined with the road network creates a unique environment with more then 250 bridges built in the city. John Ince in his book A City of Bridges beautifully describes the evolution of Christchurch bridges over the Avon and Heathcote rivers. 2010 and 2011, the years of the Canterbury earthquakes, changed the history of Christchurch bridges dramatically. Although no bridge collapsed, the city has been disrupted by loss of functionality of many bridges; more than 50% of the bridge stock needs repair work or to be replaced. The Avon river precinct in CBD will be conceived with new pedestrian bridges. In the next five years Christchurch has the opportunity for a change. But in which direction? How can we turn Christchurch in "the city of bridges"? Should we invest resources and funds for more iconic bridges? Can we improve the post-earthquake functionality of our bridges or are we prepared to accept the same traffic disruption we had in 2011? The presentation will address these questions and give an overview of the activity that the UC bridge engineering group is carrying out by supporting bridge designers, City Council and SCIRT (Stronger Christchurch Infrastructure Rebuild Team).
