Laurie Wiegler explains why it took a tragedy to build a better bridge for Minneapolis. IT IS MORE than a year since the collapse of the Interstate 35W Bridge in Minneapolis, Minnesota on 1 August 2007. The disaster left 13 people dead and over 100 injured. Now the city is focusing on the imminent opening of a swanky USD235m replacement, to be called the St Anthony Falls Bridge. But even now the official cause or causes of the collapse are not known - at least publicly. That won't occur until mid-November, when the US National Transportation Safety Board (NTSB) releases its ruling. Meanwhile, the construction team, a joint venture of Colorado-based Flatiron and Seattle's Manson, has worked tirelessly since last October on the new bridge, designed by Figg Bridge Engineers of Tallahassee, Florida.
