Parts for Bailey bridges. At a depot somewhere in England, Allied soldiers .... parts for Bailey bridges, new type spans used by ..... in Italy and France, which can cross any gap 240 feet wide without the aid of pontoons. With pontoons, the bridge can cross even wider gaps. The parts fit together like a jigsaw puzzle. Engineers first fit the parts on rollers on a embarkment and then push to spans over the crossing without using any mechanical aid. There are 17 parts to the spans and nine for the foundation. Each joint has only one steel pin.
