The British Blood Pontoon MkII, which took the original and cut it into two halves, was still in use with the British Army in 1924.

The First World War saw developments on "trestles" to form the link between a river bank and the pontoon bridge.
Some infantry bridges in WW1 used any material available, including petrol cans as flotation devices.

The Kapok Assault Bridge for infantry was developed for the British Army, using kapok filled canvas float and timber foot walks.
 America created their own version.

Folding Boat Equipment was developed in 1928 and went through several versions until it was used in WW2 to complement the Bailey Pontoon.
 It had a continuous canvas hinge and could fold flat for storage and transportation.
When assembled it could carry 15 men and with two boats and some additional toppings it could transport a 3-ton truck.
Further upgrades during WW2 resulted in it moving to a Class 9 bridge.
