Langlois Bridge is a very big and strong bridge that people built a long time ago in France. It was made of wood and was built over a river so people could cross the river without getting wet or swimming.
The way the Langlois Bridge was built was very special because it used trusses. Trusses are like big triangles that are made of wood and are put together to make a strong structure. Think of a triangle like a pizza slice, but instead of cheese and toppings, it's made of wood and is very strong!
The Langlois Bridge was built by a man named Gustave Eiffel, who also designed the famous Eiffel Tower in Paris. The bridge was named after a French engineer named Paul-Auguste Langlois.
The Langlois Bridge is important because it is an example of how people used to build bridges a long time ago. Even though it was built over 100 years ago, it is still standing today and people can still use it to cross the river.
