Bridge Unit Study - Lesson 6: Hanging Bridge Model

My son built a hanging bridge.

Although hanging bridges are rarely used today for transportation, they can make wonderful play structures. The one shown below is at a high ropes course. The hanging bridge is mounted on a pulley to a cable. The bridge is controlled with the rope to pull it near, and by gravity when traveling to the other end.

A similar bridge can be constructed over a calm waterway by attaching a floating raft to a cable spanning the waterway.



The book Bridges: Amazing Structures to Design Build and Test was the inspiration for this activity as it has been for most of our other bridge modeling projects.


This time, two straws were attached to a piece of cardboard to run on the main cables of the bridge.

Again, my son used two chairs as the main supports for his bridge.


A basket was hung from the cardboard pulley system to transport traffic across the bridge.
