Photo description: This Knex bridge has been designed for maximum strength. It uses a lot of Knex pieces and can hold large weights as the move from one side of the bridge to the other. The beams are supported by multiple joins and cross beams, forming a nearly indestructible bridge. The finished product is put between two tables as a weighted truck drives over the top, testing its strength. A student can be seen in the background working on another Knex bridge design.
