Lift Bridge Educational Wood Kit

One of the most common types of bridges for freight trains, the Truss Design Lift Bridge is a working replica of the many lift bridges that have been made over the last 100 years. Lift bridges became the workhorses of the freight railroads for many years as rail lines expanded over the rivers and ports of the world. The design was particularly useful in areas where there was no room for a bridge to swing, such as a busy industrial port. This bridge uses a small handle and crankshaft to lift the center span to the top of the truss structure, allowing trolls and other vehicles to safely pass between the two ends. The kit can be mostly made without glue and taken apart for storage. Snug slot construction and accurate cutting makes this possible! Kit comes complete with easy to follow instructions, all you need are some scissors. Comes with great educational information and links to learn more about levers and bridges. Easy to make in an hour or two, and has stickers for signs and the road Great for any bridges unit at school!
