UK engineers have cast doubt on the buildability of a competition winning bridge design, selected by the mayor of Krakow, Poland. Local architect LewickiLatak beat international competition with its design for a 140m span pedestrian bridge across the River Wisla in central Krakow. The pedestrian bridge would be constructed in steel and could be built for less than the $9.5M maximum price specied by its client, the City of Krakow, a spokesman said. But Ian Firth, partner in specialist bridge consultancy Flint & Neill, cautioned that the design was an example of 'the crazy designs that have arisen when sufcient attention has not been paid to engineering, whether in the designing or the judging of entries. As you can see it is unbuildable and a structural impossibility.'
