Gateways to New York: Othmar H. Ammann and his bridges

剧情：

The story of the great Swiss engineer Othmar H. Ammann, who moves away in 1904 and redefines the rules of bridge construction in America - for decades and in a spectacular way. The beginning of motorisation, the post-war years, urbanisation and the consumer society: Ammann is not only in the middle of it, he is with his bridges a dynamic player, an agent of progress - and the belief in it.
