if you build an arch bridge it can hold more weight then anyother type of toothpick bridge and can hold about 20lbs (if made well) another good type of bridge is the truss bridge it is just as strong as the arch bridge but it has diffrent structures.
What is the purpose of the keystone of an Arch bridge?

How does a arch bridge use compression?
An arch bridge uses compression to hold itself together

How does an abutment support an arch bridge?
the abutments at either end of the bridge anchor the arch so that it will not collapse, the weight of the arch is supported by the abutment on either end
How does an arch support itself?
Bridges are made up of triangles joined together to form a truss. Triangles are very strong because they carry weight in tension and compression instead of bending and can hold a lot more than a beam that bends can
What is the best type of bridge?
truss bridges are able to support the most weight applies to the bridge, especially when the weight is applied to the middle
What are the forces that act on an arch bridge?
The arch bridge spreads load (the weight of the bridge and the traffic on it) from the deck to the abutments (the supports at each end) and into the ground. This creates a lot of compressions.
