Bailey bridge

Bailey bridge is a special kind of bridge that can be built very quickly and easily. It is like building a special kind of puzzle. First, we make some big pieces called panels using steel. Then, we put these panels together to build the bridge.

The Bailey bridge is really helpful when we need to cross a river or move things across a big gap quickly. Sometimes, regular bridges can take a really long time to build, but the Bailey bridge can be put together much faster.

It's like using a toy building set, but the pieces are really big and really strong. It's so cool to see how fast and easy we can build a bridge using this special puzzle.
