Steel Structure Bridge Near Us
The steel structure bailey bridge emerged in 1938 and was invented by the British engineer Donald West Bailey. Bailey bridge construction was mainly used in the military in the early days. Because of its modularity and lightness, it is very suitable for quickly building temporary bridges for soldiers and vehicles to pass through. It is both strong and light.
In the mid-to-late 20th century, Bailey steel-framed bridges were improved and converted into civilian use, mainly used for transportation engineering construction, such as prefabricated highway steel bridges, pedestrian bridges, river crossings, and river steel bridges.There are various Bailey steel bridges near us, bringing convenience and romance to our lives.
