military bridging

Found a better detail photo of the bridge on the India/Burma border plus another one on our trip through Northern India

Ha! I like the contrast: 'Friendship Road' ... and a guy with an auto slung over his shoulder!

The Triple Triple (TT) had a curious way of construction: build a Triple Double (TD), launch it in to place, then add the third layer of panels, starting from both sides, in equal steps. The last step is to add the top cross braces, from the bridge span's centre and working in equal steps outwards in each direction.

The other curious thing about the TT bridge is that it requires only a TD at each bridge end panel, rather than the TT as shown here.
