Hello people,
we are learning about pontoon brides how they are built,how are they reusable,why were these bridges created.
Why the bridges are built is because they can be put up so fast and easy to get across a river in quicktime. they lay boats out then put planks after tie them together so it is safe and then it is ready to go.the bridges were created to get across a river fast and safe. these can be taken down then put up somewhere else.
