Ralph Salvucci Online Bridge Competition

October 5, 2017


The purpose of the Ralph Salvucci Online Bridge Competition is to provide middle school and high school students with a realistic, engaging introduction to engineering. The contest is open to all students in grades 6-12. Students use free software put together by The Army Educational Outreach Program to design the cheapest bridge that can carry the truck. When you click on the truck button, your design comes to life and if it can’t make it – CRASH!
Please email Alex Bonnar for more information.

The Ralph Salvucci Online Bridge Competition will provide you with an opportunity to:

  • Learn about engineering through a realistic, hands-on problem-solving experience.
  • Learn about the engineering design process–the application of math, science, and technology to create devices and systems that meet human needs.
  • Learn about truss bridges and how they work.
  • Learn how engineers use the computer as a problem-solving tool.


Monday, January 9, 2017 – Competition begins
Friday, April 21, 2017 – Competition ends
