Suspension bridges are one of the oldest engineering forms, dating back to the 4th century. Modern suspension bridges were made possible by the web truss, invented by John Augustus Roebling. The web truss made a very sturdy, rigid structure that could withstand storms, wind forces, and heavy loads.

The invention and development of suspension bridges significantly transformed American lives by enhancing transportation and connectivity across challenging terrains, such as rivers and canyons. These bridges allowed for faster travel and the movement of goods, fostering economic growth and urban expansion. Additionally, they provided a sense of freedom and accessibility, enabling communities to flourish and contributing to the overall development of infrastructure in the United States.
