What bridge is the most stable?
From the point of view of strength, Truss Bridge provides the best strengh to weight ratio. In other words, it can hold the most weight per weight of its construction materials.
What is the strongest bridge in the world?
Furthermore, the piles underneath the Incheon Bridge can withstand loads up to 6,000 tons, making it the most stable bridge in the world.
How many toothpicks do you need for a toothpick bridge?

What is the strongest truss bridge design?
In this experiment we have tested which type of truss bridge is the strongest, yet uses the least amount of material. Two of the most used truss bridges are of the Pratt and Howe design. Through our experiment it was found that the bridge design that minimized the maximum compression force was the Howe Bridge.
What is the best glue for toothpick bridges?
Official Wood glue, such as Elmer’s or Titebond Wood glue, just like it sounds, is great for wooden model bridges. Also known as PVA glue. I’ve used both Elmer’s and Titebond, both for model bridges and other wood working projects and to be honest, I can’t tell a difference.
