I made my bridge out of Popsicle sticks I layered by putting Popsicle sticks on each other then i made four of those then I put it together.The think that made it was the layer of popsicle sticks.
There is three types of bridges the Arch bridge,Beam bridge,and the suspension bridge these are the types of bridges.I made a beam bridge because when i saw it i thought it was easy to make but it was not.My bridge had to hold 15 pounds for 5 min i thought it was going to break but the layers help it hold 15 pounds.
A arch bridge holds transfer load by having a arch in the middle of the bridge,a beam bridge holds transfer load by having beams at the bottom,a suspension bridge holds transfer loads by the cables.
My blue prints was a beam but it turned into arch bridge because the beams for my were hard.
