The Bridge was made in about 1850, so that when people in like wagons and stuff were gonna cross rivers and stuff with cargo, but then they made bridges and it was easy, it used to be like, you had to like get a rope and cross, or go areound, and that was like huge miles, the bridges function was pretty much in america, it was to cross rivers and streams, and also they were used for when currents came in, the first bridges werent was good as theey are today and they did have that many different types like we do, (cable-stayed, suspension, truss, etc) and bridges relate to geometry with symetry, all the equations and al lthe corresponding parts and angles and things that they put in all have to do with geometry, im making a truss bridge and i use symmetry, with all the triangles, and things that i use and all the wight not only goes down, but to the sides, so it is designed to hold much weight, so bridges and geometry have alot of things alike.
