Prefabricated Trail Bridges

At Areté Structures, we supply prefabricated trail bridges made from lightweight fiber reinforced polymer (FRP) also called structural fiberglass. The FRP bridge material is lightweight, high strength, corrosion and UV resistant, easy to install, and customizable.

FRP Trail Bridge Design Style

Decking Design

We can design the decking to accommodate the use and purpose of the bridge. Additionally, you can choose from FRP non-skid decking or grating or timber decking.

Bridge Color

Our standard olive green color is ideal for park and trail bridges. If you prefer another option, we can work with you to modify the color to fit your needs.

Flame Retardant Resin

All of the Areté bridges can be manufactured  from FRP with a flame retardant resin in the color slate gray.

Customized Options

We can customize our bridges for your specific needs. Bridge configurations we manufacture include truss, underslung truss, or simple I-beam stringer bridges, depending on the need and design constraints. Bridges can also be customized to adjust the decking design, bridge color, and flame retardance resin to meet your needs.

FRP Benefits

FRP is a high-strength, lightweight, and corrosion resistant material.

FRP bridge parts can be easily transported, quickly installed, and extremely durable.

Remote Locations

Our FRP trail bridges are an ideal solution for remote locations. The FRP bridges are about a quarter of the weight of steel bridges.We design the individual bridge parts to weigh less than 125 lbs each. The low-weight parts make the FRP parts easier to be hand-carried to remote locations and assembled without using heavy equipment at the bridge site.


We use the Strongwell EXTREN® 500 Series FRP structural shapes for our trail bridges. This material provides many benefits and advantages for trail bridges. 

The FRP material is:

  • 100+ year lifespan
  • Corrosion-resistant
  • Durable 
  • Minimal maintenance needed once installed 
  • UV resistant

    Assembly and Installation 

    Our FRP trail bridges can typically be assembled in 1-2 days using standard hand tools. Our bridges include full assembly plans with easy-to-follow instructions, an assembly manual, and instructional video.
