The bridge design that helped win World War II

It’s a simple innovation that helped win a war.
The Bailey bridge was Donald Bailey’s innovative solution to a number of wartime obstacles. The allies needed a way to cross bodies of water quickly, but bombed-out bridges - or an absence of crossings entirely - made that incredibly difficult. That was only compounded by new, heavy tanks that needed incredibly strong support.
Bailey’s innovation - a modular, moveable panel bridge - solved those problems and gave the allies a huge advantage. The 570-pound steel panel could be lifted by just six men, and the supplies could fit inside small service trucks. Using those manageable materials, soldiers could build crossings sufficient for heavy tanks and other vehicles.
As impressive, the Bailey bridge could be rolled across a gap from one side to the other, making it possible to build covertly or with little access to the other side. Together, all the Bailey bridge’s advantages changed bridge construction and may have helped win the war.

Denys Begbie and Gwilym Roberts’ paper is a great summary of the Bailey Bridge’s achievements.

  • Eisenhower must have been havering when he said 'along with radar and the heavy bomber, the Bailey bridge was one of the most important technical advances of WW2' .What about German rocketry and the nuclear bomb? Or maybe he was just being nice to the Brits, because both of the others were, at least initially, British developments as well.... and Eisenhower was the supreme military diplomat.

  • MEXE was in Christchurch, Dorset. Opened in 1919 all that is left now is the guardhouse, there is a small section of the Bailey Bridge on the roundabout outside. It should not be forgotten that this establishment also designed many of the most extraordinary pieces of equipment for the army and also systems for the armed forces to follow to give them a tactical advantage.

  • Excuse me! The American Army put up with the under gunned, under armored Sherman for two reasons: It was fast and it would cross over the existing bridges which allowed them to chase the German retreating forces. Patton specified that the only acceptable tank would be fast, light enough to use existing roads, fit through the town streets , cross the present bridges and could be built by the hundreds. Otherwise we would have used our Heavy tanks and saved lives........simple.

  • i actually used to go over a Bailey bridge. In 1947 the Shardlow bridge in Derbyshire was washed away and replaced by a Bailey bridge. we had relatives in Derby and used to cross the bridge on the way to visit them. the traffic flow was limited and so was the speed . i used to both love traveling over the bridge and was scared it would collapse. it was replaced in 1957 when i was 10 and i was most disgruntled.

  • When I was a child there was a Bailey bridge across a river near my home. I think it was a replacement for a bridge that had been destroyed by the Germans and it made a loud noise as vehicles drove across its wooden planl decking. It was a local landmark but the thing that just surprised me was discovering that its name was the name of the its inventor.70 years ago I just thought it was a place name like Waterloo Bridge or London Bridge.

  • When the bridge (The Tasman Bridge) linking the eastern and western parts of the city I live in (Hobart, Tasmania, Australia) was partially demolished by a ship collision in the 1970s, a Bailey Bridge was constructed up river. It spanned a significant distance. I remember as a child driving over the bridge, and how it used to rattle. It served the city well for a number of years, until the bridge could be repaired, and was eventually replaced by a permanent bridge.

  • Six men, three round pieces of wood, the wood sits on the inside of your elbow, lift and trot. Line up the bottom pin then lift and insert the top one. Done it, if you are in the middle over rough ground you can end up with 200 pounds each. Thank heavens for the heavy version that needed a crane. Still a brilliant design even if the British army declared it obsolete 50 years ago.

  • Bailey Bridges are genius design. I have carried out a condition assessment on a Bailey bridge built by British Garrison in Hong Kong using War Time surplus material few years ago. The Bridge was approx 30m span with 30 ton vehicle loading capacity (actually tank load according to the design manual). The local authority worries the bridge was too old and unable to cope with local development (too many heavy traffic now). The bridge was in good condition with proper maintenence works at the time of inspection, which looks exactly the same type shown in this video. According to the design manual, the rectangular steel frame can be configured in various version. 1. LHS/RHS - single side frame. 2. LHS/RHS - double side frame 3. LHS/RHS - double side x double deck frame The more the frames, the longer the span of the bridge or the higher load capacity of the bridge. Very handy structural engineering application during war-time.

  • As a former combat engineer officer, I came to appreciate the hard work it takes to assemble these by joining in and assembling a couple bridges. This video touches lightly on how you extend span length and load carrying by going single double (side-by -side panels) or double-double (two, side-by-side panels stacked) for which you need a crane. I wonder where they all went. Are they sitting in some depot like Sierra Army Depot? I has been said Donald Bailey breached the patent on the Callender-Hamilton bridge. The only similarity is the pin system to which we best get rid of all threaded bolts. The structural designs are totally different.

  • This brings back memories! When I did my military service here in Sweden 1997-98 I did it as an engineer. Our company was a specialist bridge building company. We soldiers really appreciated this design as it was easy and fast to build. And even though we had some modern equipment at our disposal (like Volvo tractors) we usually used only hand power. Pushing out one of these bridges by hand over whatever obstacle we were facing was a mighty feeling. In Sweden the bridge is known as "balk-bro 2" ("girder bridge 2") which was a constructed name to fit the stamped parts that said "B B m.2". Fatta! Säkra! Lyft! Those were the commands when lifting one of the bridge panels. 3 people on each side holding onto the wooden lifting bars going through the panel. You really had to think about where you placed the people and match up their lengths so that the load was distributed evenly. And don't have your foot under the panel when you set it down, as one of my comrades did...
