The Great 9th Grade Bridge Project
In this project, partnerships of 2 people were established. Among the 2 groups, were a builder, to build the bridge, and the designer, to find its strengths and weaknesses, and sketch it out. The Bridge would be constructed of 16 3ft. long sticks of balsa wood, and 1oz. of balsa wood glue. Above, is the bridge I based my design on; The Hominy Creek Bridge.
Reflection
I can't say a lot about this project because I was absent during the actual construction of the bridge.
Effort
I was the official designer of the bridge. I submitted my design to Angel and he finished the building process while I was away.

Why was it built? Who mainly uses it?
The Hominy Creek Bridge was built to serve as a roadway the people. Before the original bridge from 1909 was demolished, it was a one-way bridge, the new bridge serves as a two-way roadway.
What kind of bridge is it? What structural designs are used? Beams? Steel? Was it expensive? Strong? Are there any issues with it? What are they?
The Hominy Creek Bridge is a Pratt Truss, or K-Truss roadway bridge in Osage County, Oklahoma. It's called a K-Truss because the supports in the bridge are shaped like a "K". It is built out of mostly steel, but, some parts are made of wood, like guardrails for vehicles. Today, it would've hardly cost anything, but in 1909, it was the average price to build a bridge. The 1909 build had one minor issue that wasn't up to 1990 standards and that was because it was a one way road. In 1990, the bridge was demolished and widened to fit a two way road.
