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 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!
- The Building Kit comes complete with easy to follow instructions, all you need are some scissors.

(Please Note: the makers of this kit provide links to videos on the popular Internet site, YouTube and parents should use with discretion. Loving Truth Books & Gifts is not responsible for the content or the quality of the information provided.)
- It is Easy to make in an hour or two, and has stickers for signs and the road.

Additional word of note from Loving Truth Books & Gifts: In many of the bridge building kits from this publisher, the child/ student is encouraged to paint and possibly "decorate" their bridge with graffiti. As a Christian company and family we do condone such "pretend" modeling as "tagging" or using graffiti on a bridge or other property is a form of theft and destruction and is prohibited by Scripture. As Christians, we ought to seek to honor and glorify God in all things, including imaginative play.
