The Areté Structures fiber reinforced polymer (FRP) truss bridge and underslung bridge are ideal solutions for a remote location where a long-span bridge is needed. Our truss bridges are lightweight and easy to install, which means no heavy equipment is necessary for the installation. FRP requires minimal maintenance and has a 100+ year lifespan. FRP bridge parts are small and easily transportable, learn more about FRP bridges here.
Truss Bridge
Design Style
The truss bridge design is the most cost-effective design for longer clearspans. Our design is the ideal bridge for clearspans ranging from 25 to 80 or even 100 feet long. This design option always comes with a railing, which is inherent to the truss bridge design.
Structural Design Elements
These items are essential and fundamental bridge elements.
- Foundation/abutments and piers (for multispan)
- Truss
- Floor beams and outriggers
- Stringers (supports the decking)
- Decking
Underslung Truss Bridge
Design Style
Our underslung truss bridge design is unique to Areté Structures. All the structural members (components) are below the bridge decking.
This underslung design is an excellent option for anyone wanting to add their own decking and railing material for aesthetic or functional purposes.
Our underslung design is the ideal bridge for clearspans ranging from 40 to 65 feet long.
Decking Material Options
We provide you with two decking options for your truss bridge. You can select from timber or our lightweight FRP decking.
FRP decking is maintenance-free, corrosion-resistant, and is high skid resistance. Learn more here.
