Your bridge may connect two structures, it might provide passage over a river or roadway. It might be scaffolding, a catwalk, a gangplank an arch, even a branch. The idea is, it reaches/spans/extends a distance.
Experiment with how long you can make this extention, while still keeping it stable. Also, try to see if your bridge can hold any weight. You can use coins, cars, LEGO men, whatever you like to place on your bridge to see if they can be held up.
Here are all the bridge designs kids from all over the world created for this challenge.
