What is a I-Beam Stringer Bridge? Is it right for you?

The Areté Structures I-Beam Stringer bridge (also known as beam bridge) is an economical solution for your shorter span footbridge or light vehicle bridge needs. The I-Beam Stringer bridge offers a boardwalk-style bridge design, and it doesn’t require a railing or curb. You can add a curb or handrail to the design as needed.

Areté Structures Design Style

This bridge’s design is simple, but it’s a popular and durable bridge option for many people. The bridge’s structure is made specifically for shorter spans ranging from 10 to 24 feet long. This bridge type costs less per foot since it requires less material for the overall design. 

I-Beams Design 

The Areté team uses FRP I-beams for the stringer bridge design. 

Structural Design Elements 

The below items are essential and fundamental elements of the stringer bridge.

      • Foundation/abutments and piers (for multispan)
      • I-Beams
      • Curbs
      • Decking

FRP Stringer Bridge 

Fiber reinforced polymer (FRP) is a lightweight bridge option that you can easily add to remote areas. It requires minimal maintenance and will have a long lifespan. FRP bridge parts are small and easily transportable.
