Heavy vehicles crosses Bailey bridge.

Heavy vehicles crosses Bailey bridge. A T-25 heavy duty trailer carrying full weight goes over a Bailey bridge, new type span used by the Allies in Italy and France, at a test in England. The bridge can bear more than 60 tons when built for full loads. The lighest span can carry 20 tons. The bridge is constructed in parts, build on rollers and then pushed over the gap. Without pontoons, it can cross a 240 foot gap while with pontoons it can cross still wider gaps. There are 17 parts to the spans and nine for the foundation. Each joint requires only one steel pin.
