Pedestrian Bridge

My name is Ulises Martinez, a sophomore at dalton high school. I am designing this for my engineering class and we had to do this as a project. I haven't really used tinker cad or Fusion so it wasn't like I want it to be. My personal preference is onshape it may not be as useful as the others but I consider it better than the others. This project help me learn new things and I think it helped me improve my abilities and he bridge came out better then I expected.

When designing the bridge my bridge after the Taylor Yard pedestrian bridge and I made some changes to the design. The Taylor bridge looks good and is stable so I choose to design it after it. I wanted to be different so I gave the entrance so design and made it look like the Walnut Street bridge.

I started with the bottom of the bridge and then I started making the bottom of the bridge I made a rectangle which was then 15x8 ft I extruded it upward by 1/2 foot. So that I could start to build the bridge from the bottom to the top this piece is my foundation.

Created the sides and did the same to both sides, next I made a rectangle which was 15x1 ft then I extruded it by 2.5 So when people are on the bridge they wouldn't fall off and it's also there to support the other things that the bridge needs.

I made 5 columns that were 1x1x3.5 ft and they had the same amount of space between each other so it would look better. And they were so that it could hold the top piece of the bridge which is coming later because you cant start from the bottom to the top.

Then I made the top I made a rectangle with 15x8x1/2 ft on top of all of the columns so that I could finish the bridge and we are close to finishing the bridge. You could leave it like this but i wanted to make it better

After finishing all of the previous steps I made gave some design to the entrance I made slanted columns so that it could be different from other bridges and make it look like a trapeze from the side.
