How do you create a toothpick bridge?

Well first you need to find a bridge desin that suits your needs with material and how much weight you want to hold (I suggest the truss bridge desing mostly made of triangles).
Next you put it together peice by peice, make the sides and the roof and the top seperatly then put the all together using the material you have witch is most likely going to be glue.
there you have it a toothpick bridge.
