Parallel Chord & Portal Steel Bridges
The parallel chord is the most popular truss choice. It features parallel top and bottom chords with either Pratt diagonals slanting toward the center of the span separated by verticals or Warren (W pattern) diagonals with or without verticals. Portal (overhead) bracing is used for longer spans or bridges that are fully enclosed.
Finishing Details
No bridge is complete without the finishing details. Most bridges start with weathering steel but can be finished with paint if desired. We also provide decking, railing and accessory options to complete your project.
Shipping & Installation
Bridges are shipped to the site using independent carriers with over-the-road trucks. Spans up to 80’ are typically shipped as a single unit unless requested as multiple sections at the time of order. Spans 80’ to 120’ will be reviewed to determine if they ship as a single unit or multiple sections. Spans greater than 120’ will ship in sections.
Plans include lifting weights and detailed written instruction for proper pick points and splicing (if required). Splices are field bolted.
All unloading and field installation is the responsibility of the contractor.
Urban parks offer an opportunity for accessories. Custom railing, signage, lighting, monuments can be incorporated into the bridge details.
